How HEPA Filtration Supports Consistent Infection Control Outcomes

HEPACART — Mon, 28 Sep 2026 14:00:00 GMT

Ask most facilities teams what makes filtration effective, and the answer usually starts and ends with a number: 99.97 percent. That figure is real, and it matters, but it answers a narrower question than most people think it does. It tells you what a HEPA filter is capable of under ideal, tested conditions. It doesn't tell you whether that performance shows up consistently, on job twelve, run by a crew that didn't set up the equipment on job one.

What Happens Between Cases: Breaking Down Air Exchange in the OR

HEPACART — Mon, 21 Sep 2026 14:00:01 GMT

Ask most facility teams how long air exchange in the operating room takes between cases, and you'll get a number that sounds official but rarely holds up under scrutiny. Fourteen minutes. Twenty. Sometimes "however long housekeeping needs." The truth is that air exchange isn't one event. It's a sequence of overlapping tasks, and most of the time either gained or lost between cases happens inside that sequence, not around it.

Step-by-Step: Set Up Proper Containment Systems in Active Facilities

HEPACART — Mon, 14 Sep 2026 14:00:00 GMT

A containment cart set up correctly in ten minutes and one set up carelessly in ten minutes look identical from across the hallway. Both are unfolded. Both have a HEPA unit running. Both look, to anyone walking by, like the job is under control.

Why 'We’ve Always Done It This Way' Fails Under Audit Pressure

HEPACART — Mon, 07 Sep 2026 14:00:00 GMT

Every facility has at least one process that nobody can fully explain, except to say it's how things have always been done. The barrier gets set up a certain way because that's how the last three crews did it. The negative air machine gets placed in the same corner every time because that's where it goes. The documentation gets filled out after the fact because that's always been fast enough.

6 Signs Your Infection Control Process Wouldn't Hold Up in an Audit

HEPACART — Mon, 31 Aug 2026 14:00:00 GMT

Every infection prevention leader has a version of this moment: a surveyor asks a question that sounds simple, and the honest answer isn't as clean as it should be. "Can you show me the pressure log from the job on 4 West last month?" "Who verified this containment barrier before demolition started?" "Does every contractor get the same infection control briefing, or does that depend on who's running the crew that week?"

Why Room Turnover Speed Is the Wrong Test for HEPA Filtration

HEPACART — Mon, 24 Aug 2026 14:00:00 GMT

Ask almost any facilities director, ASC administrator, or project engineer why they haven't upgraded their air management equipment, and the answer usually comes back to some version of the same sentence: "We can't afford to slow the room down."

What Most Teams Get Wrong About Negative Air Machines

HEPACART — Mon, 17 Aug 2026 14:00:00 GMT

There's a specific moment on almost every healthcare construction job where someone points at a running negative air machine and says some version of, "We're good, that's handled." The unit is plugged in. It's making noise. Air is moving. To a crew under schedule pressure, that reads as compliance.

Infection Control Equipment That Holds Up Under Audit

HEPACART — Mon, 10 Aug 2026 14:00:00 GMT

Most infection control equipment gets evaluated the same way: specs, price, availability. Can it fit through the door. Does it move easily between units. Is it in stock this quarter.

Where Air Exchange Bottlenecks Start Creating Schedule Pressure

HEPACART — Mon, 03 Aug 2026 14:00:00 GMT

When a healthcare construction phase falls behind, the first explanation is almost always the same: not enough hands on the job, a trade running late, a crew short a foreman. Staffing gets the blame because it's visible. Someone can point to an empty slot on the schedule and say that's the problem.

7 Signs Your Dust Containment Strategy Is Failing in Active Facilities

HEPACART — Mon, 27 Jul 2026 14:00:00 GMT

Nobody wakes up and decides to run a bad dust containment system. Failures in active healthcare facilities almost never happen that way. They happen gradually, one shortcut at a time, until the shortcuts become the process. A barrier that isn't fully sealed becomes "close enough." A negative air machine that's running but never verified becomes "probably fine." A crew that sets up differently than the last crew becomes "just how that team does it."
