Air Pollutant Control Leader LEV-CO Inc. Introduces World’s First Standalone COVID-19 Air Purifier Employing ‘Clean-to-Less-Clean’ Air Movement for Workplaces

As recommended by CDC, a “Clean-to-less-clean” air distribution method is crucial to protecting workers from respirable viruses and preventing viral spread

Clean air industry leader LEV-CO Inc. announced today the world’s first commercially available standalone COVID-19 air purifier and ventilation solution designed specifically to capture and filter out microscopic airborne virus particles in workplace meeting and lunchroom settings.

The LEV-CO ICA 2-Zone Air Defence solution is the only standalone COVID-19 ventilation system in the world to employ the “clean-to-less-clean” air movement and distribution method recommended by the U.S. Centers for Disease Control and Prevention (CDC).  In so doing, the system dramatically reduces the potential airborne spread of coronavirus particles, a risk many global public health officials say may be greater than originally believed.

“The World Health Organization (WHO), CDC, Public Health Agency of Canada (PHAC) and other internationally recognized public health agencies have all recently increased their risk assessment for the potential airborne spread of coronavirus particles in the COVID-19 pandemic,” says LEV-CO founder and president Robert Dinsmore.

“That’s why there’s such a great need for effective and safe ventilation and purification solutions to help eliminate the potentially virus-laden aerosols in a variety of workplace settings and effectively minimize any opportunity for aerosol viral spread,” Dinsmore says.

“Unfortunately, almost all indoor ventilation systems today are designed in a way that mixes fresh filtered air with any non-filtered air that is already present, a situation that creates the perfect environment for aerosolized viruses to be transferred from one person to another,” he adds.

To address this challenge, the LEV-CO ICA 2-Zone Air Defence COVID filtration system has been designed specifically to safely clean and exchange the air in meeting and lunchrooms using a true HEPA H14 filtration system.

The way it works is that a fan unit in Zone 1 distributes purified air down toward the room’s meeting or lunch table at an air change rate (ACH) of up to 60 times an hour. This creates a localized clean air zone – or bubble – around each person seated in the target area. At Zone 2, the principles of “clean-to-less-clean” come into effect as any potentially virus-laden air is directed to the floor where it is extracted and filtered and provides an ACH of six times per hour.

Deploying the same type of two-zone HEPA H14 filtration system used in hospital patient care areas and ambulances, the LEV-CO ICA 2-Zone Air Defence COVID-19 air purifier and ventilation solution has been designed according to recommendations by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to remove 99.995% of aerosolized viral and bacterial particles with a size down to 0.1 micrometers, a level which is known to include the SARS-CoV-2 virus associated with COVID-19.

Public health-mandated physical distancing protocols must still be followed, however, as the system does not completely protect against viral transmission through droplet-borne particles released orally at close distances.

The LEV-CO ICA 2-Zone Air Defence COVID-19 workplace air purifier solution can be mounted and operational within two hours without the need for skilled installation assistance. The units come in two sizes, one suitable for filtering air in a room up to 400-square-feet in size and a larger unit for rooms of up to 800-square-feet in size.
