Reduced risk for any indoor environment where unrelated individuals share space.

Cleans The Air That We Share to "Clean Room" standards, providing The Cleanest Air Humanly Possible continuously, for five years without a filter change.


It protects against infectious exposure to airborne diseases such as all variants of Covid, the flu, the common cold, mumps, measles, whooping cough, tuberculosis and diphtheria.

Removes all airborne particulates, aerosols, mold, pollen, pollution, dust, dander, powder—no matter how small—that pass into the HEPA filter, which captures them and then continuously removes any new ones.

– “Best In Class” room air mixing

– “Best In Class” RECAPTURE INDEX—Less Than 4%

– “Best In Class” filter life--Five Years, No Filter Replacement Needed. Guaranteed.

– “Best In Class” Clean Air Delivery Rate per Watt — “CADR/W” (140 CFM/0.7 W)

– APPROVED BY the California Air Resources Board (CARB)

– As RECOMMENDED by the US EPA, the US CDC and ASHRAE—the American Society of Heating, Refrigeration & Air Conditioning Engineers

– UL Listed

Designed by Clean Room and Data Center experts with decades of experience modeling air flows in all types of rooms.

For individuals, offices, commercial and other locations.

Technical details

Based on the 2500 Series Clean Air Curtain with UVGI


Our high-velocity clean
air plume combines with

A State of the Art HEPA Filter that captures 99.995% of ALL particles that pass through it, including COVID-19, Influenza, Common Cold etc.

Optional Ultra-Violet Germicidal Irradiation (UV-C UVGI) which kills all captured virus particles within seconds

Rapidly and uniformly cleans the air in a room leaving no lingering clouds of noxious particles or aerosols
Protects AGAINST person-to-person infections by pushing air UP and AWAY instead of sideways or downwards

Our Patented Design

The Clean Air Curtain’s Patented design draws unfiltered air in—from both sides—and sends fresh air out the top in a high velocity curtain of “the cleanest air humanly possible”.

Unfiltered Air Coming In Both Side

Here we see one horizontal plane of unfiltered air coming in to both sides of the three-dimensional model; blue is low velocity air flow. This graphic shows the velocity of a sample plane; air is actually drawn in from top to bottom and from front to back—and through the pre-filters on both sides.

Air Velocity Increases as it nears the blower intake

Here we see the air passing through the pre-filter, with increasing velocity as it is drawn into the blower. Air is a fluid, and just as a stream speeds up when it narrows, this air is drawn into a narrow opening—which means its velocity increases. The cleaning of the air begins with this step: 85% of particles are captured.

Air is blown into the supply chamber, just below the HEPA filter

The air that has been drawn into the blower is now pushed into the supply chamber, just below the HEPA filter. Our optional UV-C treatment is applied at this point. The Ultra-Violet Germicidal Irradiation (UVGI) uses the UV-C band of light to inactivate— or “kill”—99% of active particles within seconds.

Air is pushed past through the supply chamber and into the HEPA filter

Here the higher velocity air is passed through our state-of-the-art HEPA filter—which is more than 3.5 inches thick and captures 99.995% of any particles remaining after the previous steps. The blue arrows show the uniform flow through the filter as it captures all particles.

Air is pushed out the HEPA filter and out of the unit

Here the uniformly organized air flows through and out of the HEPA filter—note the curvature as it flows into and then out of the vent. At this point—as indicated above—the smaller opening leads to a significant increase in velocity: air leaves the Clean Air Curtain at approximately 2,500 feet per minute.

Here we also see the air curtain effect—which extends upwards to at least 20 feet, more if the ceiling is higher. Once it reaches the ceiling, it spreads evenly throughout the room, having a beneficial mixing effect, diluting any pathogens with the cleanest air humanly possible at distances up to 50 feet away.

The results above are estimates.

Use at least one unit per room, unless the room shares air with another.

If you have questions, please don't hesitate to contact us. Your safety and health are our first concern.

If the room has a complicated layout, or is hard to measure, not to worry!

We offer assessment services that include measurements and inspections, including the layout, HVAC, &etc., to help ensure the Cleanest Air Humanly Possible.

We also offer 3D simulations to calculate the airflow and help you manage to the best results.

This process will often save you money.
