Beyond Particle Counts: The Real Standard for Clinical-Grade Air

Most air-quality systems focus on one thing: particle counts. It’s an easy metric to measure, and it creates the impression of “clean air”.

But in labs and other contamination-sensitive environments, both particles and viable microorganisms pose a real threat.

Bacteria, fungi, and spores are invisible to the eye and barely detectable through particle readings alone. Yet even a single colony forming unit (CFU) can compromise a product, disrupt a process, or contaminate an entire facility. Millions of harmless dust particles may pass through the air without consequence, but one live microorganism is sometimes all it takes to cause failure. This is where traditional filtration falls short, and where clinical-grade air begins.

Why CFUs Matter More Than Just Particle Counts

Particle counts tell you how much is in the air. CFUs tell you what is in the air, and whether it’s alive.

Humidity, airflow complexity, human activity, and biological load make controlling viable microorganisms extremely challenging. Achieving zero CFU is rare, and it’s the true benchmark for high-risk environments across biotechnology, pharmaceuticals, electronics, agriculture, research facilities, and food production.

Case Study: PsyLabs

PsyLabs, a mushroom cultivation facility, operates in one of the toughest air environments: warm, humid, and rich in microbial spores.

To regain control of airborne contamination, they installed HiboScreens. This technology uses the physics principle that opposite charges attract, causing particle fusion. Once the particles are fused together, even standard G4 filters can capture dramatically more. No HEPA units, no major retrofits, no energy penalty.

The outcome:

For the first time, PsyLabs recorder 0 CFUs for both bacteria and fungi.

“Achieving 0 CFU in such challenging conditions is a game-changer,”

— Neil, Mycologist at PsyLabs

This isn’t just cleaner air, it’s clinical-grade air delivered through existing HVAC infrastructure.

Hiboscreen: The difference that matters

Most systems clean the air by forcing it through higher-grade, thicker filters, using more energy and reducing airflow. HiboScreen takes a different path.

By engineering the air itself, we make particles and microorganisms easier to capture using existing filters.

The result is simple, powerful, and measurable:

            •          Fewer particles

            •          Zero CFUs

            •          Lower energy use

            •          No bulky systems or complex retrofits

That’s what clinical-grade air looks like.

Why Zero CFU Is the New Standard

If your environment is sensitive to contamination, whether a lab, cultivation room, research facility, or clean production area, particle counts aren’t enough.

You need control over viable microorganisms, not just dust.

HiboScreen delivers a new benchmark: clinical-grade air powered by existing HVAC systems, enabling facilities to reach zero CFU performance consistently and cost-effectively.

We believe true air safety isn’t about what you can see. It’s about eliminating what you can’t.
