Launching: The Drive DeVilbiss 5L Compact Home Oxygen Concentrator

Sanket Jain — Thu, 11 Jun 2026 16:45:58 +0000

Big Performance, Small Footprint

If you’ve been waiting for a home oxygen concentrator that doesn’t dominate your living room, we have good news. The new Drive DeVilbiss 5L Compact 555DS Home Oxygen Concentrator from Drive DeVilbiss Healthcare has arrived at the Oxygen Concentrator Store. And it’s one of the smallest, lightest, and quietest 5-liter home units we’ve ever carried.

The 5L Compact delivers continuous flow oxygen from 0.5 up to 5 liters per minute in a cabinet that’s about 33% smaller than previous 5-liter models. At just 18.4 inches tall and under 10 inches deep, it tucks neatly beside a couch, nightstand, or favorite reading chair without getting in the way.

Light Enough to Move Where Life Happens

At only 29.9 pounds, 10 to 15 pounds lighter than many comparable home concentrators, the 5L Compact is far easier to reposition around your home. With its built-in top handle and smooth-rolling casters, moving it from the bedroom to the living room doesn’t have to be a two-person job. The compact, low-profile design also means fewer tripping hazards, which matters when oxygen tubing is already part of your daily routine.

Whisper-Quiet for TV, Conversation, and Sleep

Noise is one of the most common frustrations we hear about with home oxygen. The unit operates at a whisper-quiet 46 decibels or less, a low, pleasant hum rather than a constant drone. That means easier phone calls, clearer TV evenings, and a more restful night’s sleep for you.

Easy to Read, Easy to Use

A clear digital display shows your flow setting and unit status at a glance, no squinting at tiny dials. A simple knob adjusts the flow, and built-in visual and audible alerts let you know right away if anything needs attention, with guided troubleshooting to help you sort out simple issues like a kinked tube or blocked filter without a service call.

Savings on Your Power Bill, Too

The 5L Compact draws just 290 watts during normal use, that’s a 17% reduction in power consumption compared to prior models. For a device that often runs many hours a day, that efficiency adds up on your monthly electric bill. Running cooler also helps internal components last longer, so the unit is built to keep working reliably year after year.

Built to Last, Assembled in the USA

DeVilbiss 5L Compact 555DS is proudly assembled in Somerset, Pennsylvania, on the same lines where DeVilbiss has built respiratory equipment for decades. It’s backed by a 3-year limited warranty and designed for a 5-year expected service life; dependability you can count on for the long haul.

Easy Breathe-Friendly Meals for Low-Energy Days

Kristina Diaz, RRT — Tue, 09 Jun 2026 12:58:37 +0000

Living with a chronic condition that causes shortness of breath, like COPD, can sometimes make cooking and eating feel like a chore. On high-fatigue, low-energy days, just the thought of cooking, chewing, and digesting meals can leave you feeling completely drained and breathless. When your energy is at zero, you need meals that require minimal effort to prepare and won’t leave you feeling breathless after eating. This guide will help you put together quick, breath-friendly meals packed with nourishment.

Why the Right Foods Matter

Every time you eat, your body has to convert that food into energy–this process is called metabolism. Metabolism requires oxygen (O2) to break down nutrients, and it produces carbon dioxide (CO2) as a waste product, which your lungs have to exhale.

When you’re already short of breath, you want a metabolism that doesn’t need to produce extra CO2 for your lungs to exhale. To prevent yourself from becoming even more short of breath, focus on low-carbohydrate foods (or choose the right carbs), smaller meals, and foods that require less chewing.

Keep it low-carb, or choose the right carbs. Different foods produce different amounts of waste. Out of the three macronutrients, protein, carbs, and fat, carbohydrates produce the largest amount of CO2 when metabolized. A low-carb diet can lighten the workload for your respiratory system. When you do choose carbs, opt for fiber-rich complex carbs, like brown rice, beans, or lentils. Fiber helps slow digestion, providing a more gradual release of CO2.
Eat smaller meals. When your stomach is full, it puts pressure on your diaphragm, restricting your lungs and making it harder to breathe. Instead of three large meals, aim for 4 to 6 nutrient-dense meals throughout the day.
Minimize chewing. Tough or really dry foods require a lot of chewing, which can change how you normally breathe. Choose softer, tender foods on low-energy days so eating takes less effort.

Low-Energy Foods to Keep on Hand

The secret to surviving a low-energy day is to prepare when you do have some energy. Stock up on these ingredients–they’re already prepared, require almost no cooking, and are naturally soft. And, as a bonus, you can turn them into a meal in about five minutes.

Remember, prepare and store these foods on a higher-energy day.

Rotisserie Chicken: A game-changer for quick, easy meals. Shred the meat while it’s still warm, and store it in airtight containers in the refrigerator. Tip: Don’t throw away the bones. Dump them into a slow cooker with water to make your own homemade, nutrient-dense bone broth. Freeze the broth in small portions for future breath-friendly meals.
Pre-Crumbled Cheese: Effortlessly add feta, goat cheese, or shredded cheddar into warm dishes for extra flavor.
Pre-Cooked Ground Meat: Brown a pan of ground turkey, beef, or chicken with your choice of seasonings. Portion into freezer containers or bags. (You can thaw them in the microwave in under a minute.)
Avocados/Pre-Made Guacamole: Avocados add a rich, soft texture to meals. If fresh avocados go bad too quickly for you, make guacamole and freeze it in single-serving containers.
Frozen Mashed Cauliflower: You can find this in the freezer aisle at most grocery stores. It gives the comfort of mashed potatoes with a much lower carbohydrate load.
Hard-Boiled Eggs: Perfect for a quick snack or an addition to your meals.

Shelf-Stable Foods to Keep on Hand

Microwavable brown rice, quinoa, or lentil pouches: These pouches are hot and ready to eat in 60 to 90 seconds.
Canned fish: Foil pouches or pop-top cans make it easy to get some instant protein.
Canned beans/chickpeas: Black beans, pinto beans, and chickpeas are excellent, no-cooking-required, slow-burning carbohydrates. Just rinse a can and store it in the fridge.
For added moisture and tenderness: Keep mayonnaise, Greek yogurt, olive oil, sour cream, and broth on hand.

Breathe-Friendly Snacks–No Assembly Required

Keep these high-protein, low-carb snacks on hand for quick, on-the-go snacking.

Hard-boiled eggs
Cheese sticks
Cottage cheese cups
Bone broth for sipping
Deli turkey or ham roll-ups

Breathe-Friendly Meal Ideas

Here are five low-effort meal ideas for low-energy days.

The 5-Minute Taco Bowl

Taco bowls–or taco salads– require no cooking if your meat is already prepared. Reduce your carb intake by skipping the hard shell or tortilla and use lettuce or bagged greens as the base.

Base: a handful of crispy lettuce or bagged greens. To add some complex carbs, add a small amount of rinsed black beans or pinto beans.
Protein: In the microwave, warm up some precooked ground meat or rotisserie chicken and use it to top your lettuce or greens.
Toppings: Top with sour cream, shredded cheese, avocado, and any veggies you want. (Tip: Greek yogurt works well in place of sour cream and also adds some extra protein.)

Warm and Comforting Mash

Soft, warm foods are comforting and easy to swallow, reducing the risk of breathlessness while eating.

Base: Microwave your frozen mashed cauliflower and use a scoop as the base for some complex carbs.
Protein: Stir in the pre-cooked shredded chicken or ground meat.
Add a boost: Add a splash of bone broth to make it extra moist, then microwave until warm.

Salmon-Avocado Boat

Avocado is packed with healthy fats for sustainable energy and doesn’t produce extra CO2 for your lungs to exhale.

Base: Avocado. Cut in half and remove the pit.
Protein: Open a pouch of wild-caught salmon (or tuna), and mix it with mayonnaise or Greek yogurt directly in the pouch. Optional: Add a dash of pepper and a squeeze of fresh lemon.
Assemble: Scoop your fish mixture straight into the avocado halves, then eat them with a spoon for minimal effort and chewing, with the perfect balance of healthy fats and protein.

Chicken and Lentil (or Brown Rice) Bowl

Lentils are packed with fiber and protein, making them a complex carb. They’re soft when cooked, making them effortless to chew.

Base: Microwavable pouch of steamed lentils or brown rice. Heat for 60 to 90 seconds (as directed on the pouch), then scoop a small portion into a bowl.
Protein: Top with a handful of pre-shredded rotisserie chicken.
Assemble: Mix in some feta or goat cheese, and drizzle with olive oil.

Egg and Avocado Salad Bowl

This low-carb meal uses avocado for a creamy, soft texture with healthy fats with little effort.

Base: Add about a half-cup of canned chickpeas for some complex carbs.
Protein: Use a couple of hard-boiled eggs and slice them right over the bowl with a butter knife or a fork (no cutting board needed).
Assemble: Throw in some avocado or pre-made guacamole. Add mayonnaise or Greek yogurt, salt, and pepper, and stir it all together.

Tips for Difficult, Low-Energy Days

Clear your airways before eating by using your bronchodilator or airway-clearing techniques before sitting down to eat.
Sit up straight and avoid slouching to leave room for your lungs and stomach to expand.
Use small bowls to keep your portions small. You can save extra food in the fridge for another meal.
Pace yourself; chew slowly and remember to breathe. If you start feeling short of breath, put your fork down, focus on your breathing, and come back to your food when you feel ready.

Prep Ahead Shopping List for Low-Energy Days

Produce

Rotisserie Chicken (Shred immediately; don’t wait until a low-energy day.)
Avocados (Choose some ripe and some not so ripe for future use.)
Pre-washed bags or containers of chopped or shredded lettuce or greens
Lemons and limes to add flavor

Refrigerated Food

Eggs. Boil them when you get home, or buy pre-cooked, pre-packaged hard-boiled eggs.
Sour cream or plain Greek yogurt
Pre-shredded or crumbled cheeses
Pre-made guacamole (if you don’t want to prepare fresh avocado)
Cheese sticks and cottage cheese cups

Center Aisles

Microwavable brown rice pouches
Microwavable lentil pouches
Canned or pouched fish (choose pop-top can lids)
Canned beans
Olive oil and Mayonnaise
Bone broth

Sleeping with Continuous Flow Oxygen Concentrators

Scott Ridl and Sanket Jain — Mon, 08 Jun 2026 14:09:44 +0000

Achieving restful sleep is essential, especially for individuals requiring continuous oxygen therapy. Selecting an appropriate continuous oxygen concentrator can significantly influence sleep quality. Below, we delve into key considerations to ensure your device supports a peaceful night’s rest.

To assist you in choosing, here is a list of common concerns that patients, caregivers, and clinicians have when choosing a concentrator that won’t disrupt sleep:

Noise Level
Continuous Oxygen Flow
Power Source
Energy Consumption
Weight of Unit
CPAP Compatible

Eliminate Sleepless Nights with the Right Oxygen Concentrator

Before we start the comparison discussion, there were a few guidelines we followed to narrow down the list. Each concentrator has at least two of the following features:

Continuous oxygen flow
2 liters per minute (LPM) of oxygen output or more

Every concentrator in the list below meets these guidelines:

1. Noise Level

The most obvious concern is the noise level it can produce while you’re trying to fall asleep. Fortunately, most manufacturers have built their concentrators with low ambient noise levels. Modern devices typically emit between 37 and 48 decibels, akin to a quiet conversation. Every other unit on this list is either 40 or 45 decibels. In the larger context, anything below 48 decibels will be quiet.

The video below will show you the side-by-side difference between gradual decibel changes. Start the video at (0:35) to hear the difference of a 5 decibel sound reduction and at (0:50) to hear 10 decibels of sound reduction.

The most dramatic difference is certainly the 10 decibel sound reduction.

The CAIRE Eclipse 5 Portable Concentrator comes in at 40 decibels on continuous flow. That’s quieter than a library or birds chirping outside your bedroom window. One reviewer for this concentrator stated, “My friends and family have mostly commented on how much quieter it is…”. Similarly, the Drive DeVilbiss 5L Quiet is known for its quiet operation, making it suitable for nighttime use. Choosing a concentrator within this decibel range can help maintain a peaceful sleeping environment.

2. Continuous Oxygen Flow

For most people, continuous oxygen flow is the easiest way to manage daily oxygen needs. During sleep, breathing patterns often become slower and shallower, and many individuals tend to breathe through their mouths. Pulse-dose concentrators, which deliver oxygen based on detected breaths, may not provide adequate oxygen in such scenarios. Therefore, devices offering continuous oxygen flow are recommended to ensure consistent oxygen delivery throughout the night, accommodating varying breathing patterns.

Amongst portable concentrators, Eclipse 5 and Oxlife Independence can reach a maximum of 3 LPM (liters per minute); and Oxlife Liberty2 and GCE Zen-O can reach 2 LPM. If this covers your requirement you can use a portable unit for your nighttime continuous flow oxygen needs.

However, if you need up to 5 LPM of oxygen, all of the stationary concentrators listed above are capable of meeting your needs. Since stationary concentrators are larger and equipped with a stronger compressor, they can supply higher levels of oxygen.

3. Power Source

Another thing to consider when purchasing an oxygen concentrator for sleep is the source of power. If your power goes out and you’re asleep, you may not even notice it. For this reason, it’s essential to have a backup plan for your oxygen unit in case this happens to you.

All of the portable oxygen concentrators listed above have AC (wall outlet), DC (car charging), and battery power sources.

The stationary oxygen concentrators all run on AC home outlet power. Of these concentrators, only the CAIRE Companion 5 has a power failure alarm. That is an important feature in the event of a power failure. If your power were to go out while you were asleep, you’d like to know right away so you could get a backup oxygen tank or a battery-powered concentrator.

Intro to Continuous Flow Portable Concentrators Video

4. Energy Consumption

Across the board, portable machines consume less power. That’s because their maximum oxygen-flow output is 3 LPM. In general, the more oxygen flow you use, the more power your concentrator will consume. The average power consumption is 145 Watts. Let’s see how that compares to the stationary concentrators.

The Inogen At Home Concentrator (Stationary) is the only stationary concentrator that beats all the portable concentrators on power consumption at 120 watts at 2 LPM. The other stationary concentrators use anywhere from 275–600 watts of power. But again, lower liter flows will always require less power, even on the stationary concentrators. Evaluating the energy specifications of a concentrator can inform cost-effective decisions.

5. Weight of Unit

The portable concentrators are the obvious choice here because they’re made to be transported easily. Every portable concentrator is under 20 pounds, with the Oxlife Liberty2 coming in with the lightest weight at 6.35 pounds.

The Inogen At Home Concentrator (Stationary) is also very competitive with portable units when it comes to weight, coming in at only 18 pounds. Most stationary concentrator weighs anywhere from 36–58 pounds. If you want the lightest unit, your best option includes any portable concentrators or the Inogen At Home Concentrator. Considering the weight and design of a concentrator ensures it aligns with your lifestyle and mobility needs.

6. CPAP Compatible

Integrating a Continuous Positive Airway Pressure (CPAP) machine with an oxygen concentrator is essential for individuals managing both obstructive sleep apnea (OSA) and conditions requiring supplemental oxygen, such as chronic obstructive pulmonary disease (COPD). This integration ensures that while the CPAP maintains open airways during sleep, the oxygen concentrator delivers the necessary supplemental oxygen to maintain adequate blood oxygen levels. It’s crucial to ensure that the oxygen concentrator provides a continuous flow, as CPAP machines require a steady oxygen supply to function effectively.

Only continuous flow POCs are compatible with CPAP machines because they can provide a steady stream of oxygen that integrates seamlessly with the CPAP’s constant air pressure. This integration is essential for maintaining the effectiveness of sleep apnea treatment, ensuring that you receive both adequate oxygenation and airway pressure throughout the night. Choosing a continuous-flow POC enhances the therapeutic benefits, supports your respiratory health, and promotes better sleep quality by ensuring that both treatments work effectively together.

Consulting with healthcare providers before integrating these therapies is recommended to determine appropriate oxygen flow rates and to ensure compatibility between devices. Regular maintenance of equipment and inspection of connections are also vital to prevent leaks and ensure optimal therapy effectiveness.

Final Thoughts

By focusing on these factors—noise level, continuous oxygen flow, power source reliability, energy consumption, unit weight, and CPAP compatibility—you can choose an oxygen concentrator for your best night’s sleep and overall health.

Anxiety and Breathlessness

Kristina Diaz, RRT — Mon, 01 Jun 2026 13:30:25 +0000

Feeling like you can’t breathe can instantly trigger a wave of panic. Still, a spike in anxiety can just as easily make you breathless–it’s a terrifying chicken-and-egg situation.

Because our respiratory system and emotional brain are so deeply intertwined, it doesn’t matter which symptom starts first; they quickly feed into each other, creating a vicious cycle that’s hard to break. For people with lung disease, like COPD, this loop is triggered often. However, anxiety can also trigger this loop in people with healthy lungs. Understanding this bidirectional trap is the first step towards stopping the cycle and regaining control of your body.

Understanding the Anxiety-Breathlessness Cycle

The anxiety and breathlessness link is rooted in the nervous system. When the body perceives a threat, whether it’s a COPD flare-up or a stressful thought, the brain triggers the “fight or flight” response.

When this cycle is triggered, your body responds with physical changes to help you survive.

Hyperventilation: Your body works hard to take in more oxygen, and your respiratory rate rapidly increases.
Shallow chest breathing: Your body shifts from using your diaphragm (the large breathing muscle) to using your upper chest and neck muscles–this increases the physical work of breathing.
Air trapping: For people with COPD, rapid breathing doesn’t give the lungs enough time to empty, trapping “stale” air; this leaves no room for new oxygen, creating the terrifying feeling of “air hunger.”

In people with COPD, a rapid breathing rate, shallow breathing, and air trapping can lead to a buildup of carbon dioxide (CO2), clinically known as hypercapnia.

However, for people with healthy lungs, rapid, shallow breathing has the opposite effect–exhaling too much CO2; this can cause panic attack symptoms, like dizziness and chest tightness. For all people, with or without COPD, the brain takes these sensations as a sign of danger, elevating the heart rate and keeping the anxiety-breathlessness cycle going.

Stopping the Anxiety-Breathlessness Cycle

The respiratory system is autonomic, meaning your body breathes automatically, without having to tell yourself to take each breath. However, it is one of the few autonomic functions we can actively control. Purposely changing your breathing pattern sends a message to your brain that the “danger” has passed.

For people with healthy lungs, a deep inhale or holding your breath can help break the cycle by forcing CO2 levels to return to normal.

However, people with chronic lung conditions must avoid holding their breath and stick to exercises that use exhalation-focused techniques.

Breathing Techniques to Break the Cycle

These three breathing techniques are especially beneficial for people with chronic lung diseases, like COPD.

Pursed-Lip Breathing

Pursed-lip breathing means you’re exhaling through puckered lips, which creates a gentle back-pressure in your airways. The back-pressure acts like a splint, propping the airways open longer so you can empty the trapped CO2.

Inhale, breathing slowly through your nose and keeping your mouth closed.
Purse (pucker) your lips like you’re going to blow out a candle.
Exhale, breathing out gently and steadily for at least twice as long as you inhale. Do not force your air out; let it escape naturally.

Diaphragmatic Breathing (Belly Breathing)

Anxiety and panic force you to breathe from the upper chest, which uses too much energy and strains the neck and shoulder muscles. Diaphragmatic breathing retrains you to use your primary breathing muscle– the diaphragm. Using the diaphragm makes each breath more efficient and saves your energy.

Sit or lie down. Place one hand on your chest and the other on your belly, just below the rib cage.
Breathe in slowly through your nose, focusing on making the hand on your belly rise, while keeping the hand on your chest as still as possible.
Exhale with pursed lips, tightening your stomach muscles and letting them fall inward through exhalation.

Breathing with your diaphragm can feel difficult and frustrating for people with COPD–that’s okay. It takes practice for most people; continue working on learning this technique.

The Water and Straw Technique (Bubble PEP)

Commonly prescribed by respiratory therapists worldwide, this low-cost method helps clear your lungs and prevent airway collapse. Blowing into water with a straw creates positive expiratory pressure (PEP) and creates small vibrations in your airways, which help break up trapped mucus.

In addition to the medical benefits of bubble PEP, it’s also a powerful technique for calming anxiety because the resistance of the water forces a prolonged, slow exhalation, which stimulates your vagus nerve– the direct link to your parasympathetic nervous system–which slows down your heart rate and tells your brain to get out of the “fight or flight” panic response.

Prepare your setup: Fill a cup with roughly 5-10 centimeters of water, and place a straw inside.
Inhale deeply, taking a slow, deep breath in through your nose, using your diaphragm.
Blow steady bubbles. Place the straw in your mouth and exhale smoothly and continuously to create a steady stream of bubbles in the water. Focus on a long, full exhalation.

Grounding Techniques to Break the Anxiety-Breathlessness Cycle

When breathlessness triggers panic, your mind pulls you out of the present moment, and you focus on the worst-case scenario. Grounding exercises disrupt the feeling of panic and force your brain to focus on what’s happening outside of your body, like things you can see, hear, or touch, instead of feeling out of control with panic.

The 5-4-3-2-1 Sensory Method

This grounding exercise brings you back to the present moment by using your five senses.

Sight: Acknowledge 5 objects around you ( like a clock, a plant, or your pet).
Touch: Notice 4 textures you can physically feel (like your feet on the carpet or the fabric on your chair).
Sound: Listen for 3 separate sounds (a car driving by, your fan blowing, or the refrigerator humming).
Smell: Notice two distinct scents around you (your coffee brewing or your shower soap).
Taste: Focus on one thing you can taste (the roof of your mouth or a sip of a drink).

The Alphabet Game

This grounding technique helps quiet your mind’s alarms.

Choose a category, like animals or foods, and name an item for each letter of the alphabet (like alligator, bear, cougar…). This game engages a different part of your brain, so it no longer activates the brain’s emotional panic center; this stops the anxiety-breathlessness cycle.

Reclaiming Control, One Breath at a Time

The anxiety and breathlessness cycle can feel like a trap you can’t escape, but you have the power to stop it. By choosing the right techniques for your lungs, whether it’s pursed-lip breathing or grounding exercises, you can safely and effectively reset your system to catch your breath and calm your mind.

The key is practicing these techniques before you panic. Spending a little time on these techniques each day, while you’re calm, builds muscle memory so that when panic hits, you’re ready. By making them a daily habit, you give your body a reliable “emergency break” to stop this cycle when it starts.

Scott Ridl — Mon, 01 Jun 2026 13:11:46 +0000

To purchase an oxygen concentrator, you do need a prescription from your doctor, stating your oxygen level. The U.S. Food & Drug Administration (FDA) makes the rules about prescription sales, and at this time, oxygen concentrators are one of the medical devices for which the FDA requires a prescription. This is to ensure proper care has been taken in selling you an oxygen machine that is appropriate for your needs, and a prescription is the only evidence we have of exactly what those needs are.

The oxygen machine you purchase and use is also largely determined by your prescription, and that’s why you may have completely different needs from your friend who also uses supplemental oxygen, even if you both have the respiratory condition. Several important health indicators factor into a prescription for supplemental oxygen that results from a pulse oximetry test and arterial blood gas test.

Some patients who require oxygen therapy only need it when they are exercising, while others only need it while they are sleeping, and others need it for a few hours out of the day no matter what they are doing. Some patients need continuous flow oxygen, while others only need pulse dose. Exactly which type of dosage you need, how many hours out of the day you need it, and at which setting is determined by your doctor.

Your physician will administer tests to find out how much oxygen you require. They will have blood drawn for an ABG test (arterial blood gas) to check your blood gases, as well as use a pulse oximeter to monitor your blood oxygen level. The doctor will also check to see if your blood oxygen levels change drastically during exercise or while you are sleeping. Once your doctor has some measurements relating to blood oxygenation, they can write your prescription for your oxygen requirements.

Selecting the Correct Concentrator

After you receive your prescription our highly trained Oxygen Specialists will assist you in selecting the correct concentrator that will best suit your needs and lifestyle. For example, if you need a continuous flow of 3 LPM, that only narrows down the available units.

Next, we will discuss how often you will need to use your 3 LPM. Eight hours per day, during the daytime? A few hours during the morning before you leave the house? While you exercise? Only during the night? These other prescribed factors will help you narrow your search down even more.

Your prescription is a formalized way of ensuring your safety. Like all crucial medical information, you want to be sure that in an emergency, the people helping you are aware of your exact physiological need for supplemental oxygen. If you plan an airplane flight, you should notify the airline ahead of time because they may want more than just your prescription; you may be required to give them some extra certification from your physician.

After your doctor has prescribed you oxygen, we encourage you to call us for a free oxygen consultation. We will evaluate your needs and lifestyle and recommend a unit that is ideal for you. Need assistance getting a prescription? Please call us at 877-774-9271.

Celebrating 11,000+ Trustpilot Reviews — Thank You for Trusting Us!

Sanket Jain — Wed, 27 May 2026 20:07:29 +0000

In the world of medical equipment, trust is everything. At the Oxygen Concentrator Store, we know how vital every breath is, which is why we have dedicated ourselves to becoming the most reliable partner in the industry. We are honored to support hundreds of thousands of individuals, ensuring they have the right equipment to live life on their own terms.

Just a few months ago, in December 2025, we hit 10,000 Trustpilot reviews and wrote a post to say thank you. We’re back sooner than we expected. In the five months since, you’ve added more than 1,000 reviews, putting us past 11,000 and keeping our average right at 4.8 stars. About 89% of all our reviews are five stars. Roughly 19 out of 20 customers who leave a review give us four stars or more.

Reaching this number on a third-party, unbiased platform is a powerful distinction. It serves as tangible proof of our operational excellence, from our expert, compassionate consultation process to our fast shipping and lifetime support. This achievement belongs to our community of users who have trusted us with their well-being, and it fuels our drive to continue setting the gold standard in home oxygen therapy.

The story behind the number

Oxygen Concentrator Store has been serving oxygen users since 2001. More than 250,000 patients and caregivers have worked with us over those 25 years. We’re a direct-to-consumer retailer, we don’t bill Medicare, and we’re honest about that from the first conversation. We hold an ACHC accreditation (since 2012) and a Better Business Bureau A+ rating.
The 11,000+ reviews are how we know we’re still doing the job the way we want to be doing it.

What you tell us you love

When we look at the themes that appear across thousands of reviews, a handful of things come up again and again. Here’s what you’ve told us, in your own words.

“Knowledgeable, patient, and didn’t rush me.”

The single most-mentioned thing in positive reviews is the team you talked to — by name, with specifics, often with a little story attached. Words like knowledgeable, patient, and took the time appear in nearly one in five reviews.

“Knowledgeable, friendly rep. The whole buying process was easy with his help in explaining the various options and matching up the best suggestions to my needs. I recommend them highly.”

“The person I talked to was patient with me, answered all questions. Helped me make the right decision.”

“Real associates answer the phone and track incoming calls to know who is calling, immediately. Very knowledgeable, and quick to understand my situation and provide the correct advice to fit my needs.”

Every one of our Oxygen Specialists is trained on the equipment, the prescriptions, and most importantly on how to listen.

“Arrived sooner than I expected.”

Roughly one in four reviews mentions shipping speed. Same-day, next-day, “arrived before I even called for an update” — those phrases come up constantly. We know that for many of you, an oxygen order isn’t optional. It’s something you need yesterday.

“Delivery was fast and efficient… the next day! I’d still be waiting if I was dealing with the other companies I contacted.”

“Quoted price was accurate. Delivery was prompt and item worked and was as described. Rare these days.”

“My new concentrator was sent very well packaged and in perfect condition and arrived sooner than I anticipated.”

Behind every one of those reviews is a warehouse and shipping team that almost never gets named by customers — but absolutely earns the credit.

“For my mom, my dad, my husband, my wife.”

Hundreds of reviews tell us you weren’t shopping for yourself. You were figuring this out for someone you love. We see you, and we know how much pressure that can be.

“Mars helping us determine the best machine for my mother-in-law was exceptionally helpful. He walked us through the good and bad of all the machines then let us pick. He answered all our questions.”

“Felt like the salesman was family. He cared about my wife’s needs.”

“Sales person was very caring. Explained everything, what to expect. Would recommend to anyone.”

If you’re a caregiver navigating a new prescription or a sudden equipment change, that’s exactly the situation our specialists are built for. You don’t have to figure it out alone.

“I can get out and enjoy life again.”

Equipment is the means. The cruise, the road trip, the porch with the grandkids — that’s the point.

“I can breathe so easy, and this machine is so light! Thank you!”

“Love my eclipse. I have peace of Mind now.”

“All the stuff you would need to help you get out and breathe and enjoy life again.”

“Took it on a cruise and it worked perfectly.”

When you breathe easier, we breathe easier. That’s not a tagline — it’s the whole point.

“Trustworthy.”

This is the word that shows up when you’re explaining to a friend why you’d recommend us. Hundreds of reviews use words like trust, honest, reliable, did what they said they’d do.

“Trustworthy — said what they promised and went overboard to suit me.”

“It is great because foremost, I trust them!”

“I just had a good experience all around — everybody treated me with respect and honesty which I appreciate.”

Trust is the only thing this industry really runs on. Equipment, prescriptions, accessories — none of it matters if you can’t trust the person on the other end of the phone. We try every day not to give you a reason to question that.

How to Attach a Humidifier to an Oxygen Concentrator

Sanket Jain — Wed, 20 May 2026 21:15:44 +0000

If you use an oxygen concentrator, you may have noticed that the air it delivers can feel dry; especially at higher flow rates, during winter months, or while you sleep. That dryness can irritate your nose, throat, and sinuses, and in some cases even cause nosebleeds.

That’s where a humidifier bottle comes in. It’s a simple, inexpensive attachment that adds moisture to the oxygen before it reaches you. The oxygen passes through distilled water inside the bottle, picks up humidity, and arrives at your cannula feeling much more comfortable.

Not everyone needs a humidifier but if your doctor has prescribed one, or if dryness is making oxygen therapy uncomfortable, this guide will walk you through exactly how to set it up.

Before You Start: A Few Important Things to Know

Before you connect anything, keep these points in mind:

Only use a humidifier if your physician has recommended or prescribed one. It’s not required for every oxygen user.
Humidifiers work with continuous flow only, never pulse dose. In pulse mode, water can travel backward through the tubing toward your cannula. If your concentrator only delivers pulse dose (like most small portable units), a humidifier is not compatible.
Use distilled water for best results. You can also use sterile water or boiled tap water that has been cooled to room temperature. Avoid regular tap water, spring water, or filtered water. Minerals in these can cause buildup inside the bottle and shorten its lifespan. If you do use tap water, you’ll need to clean the bottle more frequently (every 3 days instead of every 14).
Make sure the concentrator is turned off before connecting or disconnecting the humidifier.
Wash your hands before handling the bottle or any of the connections.

Choosing the Right Humidifier Bottle

Some oxygen concentrator manufacturers sell humidifier bottles designed specifically for their models. If one is available for your concentrator, that’s usually the best fit.

If a manufacturer-specific bottle isn’t available, or if you’re looking for a reliable universal option, the Salter Labs Bubble Humidifier is compatible with most oxygen concentrators and is the one we most commonly recommend. Salter Labs makes several models for different flow ranges:

Model 7600: for flow rates of 3 to 7 LPM (most common for home use)
Model 7900: for high-flow rates of 6 to 15 LPM

Both have a built-in safety pop-off valve that sounds an alarm and releases excess pressure if the tubing becomes kinked or blocked.

Step-by-Step: How to Attach a Humidifier Bottle

Step 1: Fill the Humidifier Bottle

Unscrew the cap from the bottle and fill it with distilled water up to the maximum fill line marked on the side (typically around 290 ml). Don’t go above the max line, overfilling can cause too much moisture to enter your tubing and potentially your concentrator. Don’t let it stay below the minimum line either, as this means not enough moisture is getting through.

A good rule of thumb: fill to about a half inch below the maximum line.

Step 2: Replace and Secure the Cap

Make sure the threads are properly aligned before you start screwing the cap back on. Then tighten it firmly by hand, snug enough that no air escapes, but don’t over-tighten. A cross-threaded or loose cap is one of the most common reasons oxygen users don’t see bubbles in their bottle.

Step 3: Connect the Bottle to Your Concentrator

Locate the oxygen outlet on your concentrator. Using the adapter tube (sometimes called a humidifier connector or Christmas tree adapter), connect one end to the concentrator’s outlet and the other end to the wing nut fitting on top of the humidifier bottle. The adapter tube typically enters the wing nut vertically from above.

The connection should be hand-tight and secure. If your setup uses a threaded wing nut, turn it until snug. Don’t use tools or over-torque it.

Tip: Your setup may vary slightly depending on your concentrator model. Some units have a dedicated humidifier port, while others connect directly at the oxygen outlet. If you’re not sure where to connect, check your concentrator’s user manual or give us a call.

Step 4: Position the Bottle Upright

Place the bottle in its holder, support stand, or accessory pouch, depending on what your concentrator provides. The bottle must stay upright at all times. Tilting or tipping the bottle can cause water to travel up the tubing and into your cannula, which is uncomfortable and can interfere with oxygen delivery.

Step 5: Connect Your Cannula

Attach your nasal cannula (or oxygen mask) tubing to the oxygen outlet port on the side of the humidifier bottle cap, not directly to the concentrator. This is important: the oxygen needs to pass through the water first before reaching you.

The correct oxygen path is: Concentrator → Adapter tube into wing nut (inlet on top) → Through the water → Outlet port (side of cap) → Cannula → You

Step 6: Turn On and Verify Flow

Turn your concentrator on and set it to your prescribed flow rate. Look at the humidifier bottle, you should see bubbles rising through the water. This confirms that oxygen is flowing through the bottle and being humidified before reaching your cannula.

Hold the cannula prongs near your face and you should feel a gentle, moist flow of air.

If you don’t see bubbles, check the following:

Is the cap screwed on tight with the threads properly aligned?
Are the inlet and outlet connections on the correct ports (not reversed)?
Is there a kink in the tubing?
Is the adapter tube securely connected at both ends?

Cleaning and Maintenance

Keeping your humidifier bottle clean is important for both safety and performance.

Daily: Empty the bottle completely, rinse it, and refill with fresh distilled water. Don’t just top it off, replace the water entirely each day to prevent bacterial growth.

Every 14 days: Wash the bottle thoroughly with warm, soapy water using a non-scented, lotion-free liquid dish detergent. Rinse well with clean water and visually inspect it before refilling. If you use tap water instead of distilled, clean every 3 days to prevent mineral buildup.

Every 90 days (3 months): Replace the humidifier bottle with a new one. Replace sooner if you notice mineral deposits that won’t come off with cleaning.

Never use bleach, ammonia, or harsh chemical cleaners on the bottle.

Safety Reminders

Never reverse the inlet and outlet connections. If oxygen enters through the outlet instead of the inlet, it can push water backward through the tubing and into your cannula. This is the most common cause of water reaching your nose during use.
Keep the bottle upright at all times, during use and when moving it.
If the pop-off valve sounds (a loud hissing or whistling), check for a kink or blockage in your tubing. This is a safety feature, not a malfunction.
Leaks matter. Even a small leak at the cap or connections can reduce the amount of oxygen being delivered to you. If something feels off, check all connections or call us.
Don’t use a humidifier with pulse dose. It’s only safe with continuous flow delivery.

Frequently Asked Questions

Can I use a humidifier with a portable oxygen concentrator?
Only if your portable unit has a continuous flow mode. Concentrators like the CAIRE SeQual Eclipse and Respironics SimplyGo support continuous flow and can be used with a humidifier. Most small pulse-dose-only portables (like the Inogen Rove 4 or CAIRE FreeStyle Comfort) do not support a humidifier.

Do I need to increase my flow rate when using a humidifier?
No. Use the flow rate your doctor prescribed. The humidifier doesn’t change the amount of oxygen you receive, it just adds moisture.

Can I use spring water, filtered water, or RO water?
Distilled water is strongly recommended because it has no minerals. RO (reverse osmosis) water is the next best option but may still leave some mineral residue. Spring water and filtered tap water contain more minerals and will require more frequent cleaning. Avoid regular tap water if possible.

What if water gets into my tubing or nose?
This usually means one of these things: the inlet and outlet are reversed, the bottle is overfilled past the max line, the bottle isn’t sitting upright, or you’re in a very humid environment. Check your setup first. If the problem continues, an inline water trap which is a small, inexpensive device that sits in the middle of your tubing, can catch excess moisture before it reaches you.

Will oxygen still flow if the bottle runs out of water?
Yes. Oxygen will still pass through the bottle and reach you, it just won’t be humidified. Refill the bottle as soon as you notice the water is below the minimum line.

Does the humidifier bottle work with a 50-foot extension hose?
It can, but keep in mind that moisture may condense inside a very long tube, especially in cooler environments. An inline water trap can help with this.

Can I use a humidifier and a CPAP at the same time?
If you use both a concentrator and a CPAP machine with its own built-in humidifier, you typically don’t need the humidifier bottle on the concentrator as well, the CPAP humidifier is already adding moisture. Check with your doctor or respiratory therapist if you’re unsure.

Oxygen Concentrators and Heat Don’t Mix – Summer Concentrator Safety

Ryan Anthony — Wed, 20 May 2026 08:44:14 +0000

Just like any other type of electronic or piece of medical equipment that you depend on, there are things you should know about the proper safety precautions for your oxygen concentrators. With the approaching hottest months of the year for much of the country, you must consider how your oxygen concentrator will fare out in the high temperatures. High heat, and especially flames near your unit, can be extremely dangerous and harmful.

Maximum Operational and Storage Temperatures

The maximum operational temperatures vary between the different models. The maximum operational temperature is the highest temperature at which the unit will run safely. If it gets hotter than that and the oxygen concentrator is not running, it won’t harm the machine. Using it while the temperature is above the maximum operational temperature will heat up and damage the inner system and the batteries (if it uses batteries).

The maximum storage temperature is the highest temperature at which the oxygen concentrator can be stored and functioning correctly later. You can find the maximum operational and storage temperatures in the owner’s manual that came with your oxygen unit under the specifications or on the individual product pages on our website. Most of the machines can be operated safely up to 104°F (or 40°C), while they can be stored in temperatures up to 158˚F (or 70˚C).

How to Use Your Oxygen Concentrator During High Heat

It’s essential to use your unit indoors, in an air-conditioned or otherwise cool area that is well below the maximum operational temperature. Not only is it more comfortable and safe for you, but it will help your oxygen concentrator have a longer life.

The best and most comfortable temperature range and the safest for your machine is between 60 and 70 degrees Fahrenheit. If you have to use your portable oxygen concentrator outdoors, find a shaded area under some trees or by a building. Keep an eye on the weather to ensure it won’t be near the maximum operating temperature, and plan your day around when it will be safe to use your concentrator outdoors.

Signs of Overheating and What To Do in Such Situations

– Increased noise or vibration
– Unusual heat emanating from the device
– Frequent alarms or error messages on the display
– The unit automatically shuts off

If you notice any of these signs, it’s essential to take action to prevent further damage or potential safety hazards. Here’s what you can do. Turn off the unit and unplug it from the power source. Move it to a cool, well-ventilated area away from direct sunlight. Allow the concentrator to cool down for at least 30 minutes before attempting to use it again.

Stay Away from Open Flames

Open flames and sources of heat are also dangerous while using a concentrator. You definitely should never smoke a cigarette or be near smokers while using your oxygen concentrator. As a general rule, you will need to stay at least 15 feet away from lit cigarettes. You should also avoid things like gas or electric stoves, space heaters, and campfires.

You can join the fun around the campfire after using your oxygen concentrator. While it’s not in use, it should still be no less than 8 feet away from heat sources to protect it from getting too hot and ruining the outside of the concentrator.
