Air purifier testing

Project Description

Airgle is an air purification manufacturer. We have testing ? done in Japan ? on our smallest unit that shows 99.98% reduction in airborne influenza virus. We need to have testing done in the USA.

The protocol used for the test in Japan was to set up a test chamber with the unit inside. Spray aerosolized virus into the chamber. Measure the quantity of virus in the air using an impinger before starting the unit and then measure the quantity of virus remaining in the air at intervals thereafter. A natural precipitation/decay test was also run as a control.

If possible, we would like to test against several viruses ? corona virus (if this testing is possible), influenza, norovirus, as well as the common cold virus. Since the COVID19 corona virus is approximately the same size as the influenza virus, we are making analogous claims of effectiveness based on particle size, but would like to be able to have test results so that we can make specific claims to support hospital?s efforts to protect their healthcare workers.

Key features of our machines are a MERV-19 cHEPA filter (permeability tested to 0.003microns at 99.999%), UV/titanium dioxide PCO purification system and a carbon filter. We believe the ability to remove viral particles from the air is due to the MERV-19 cHEPA filter and that the PCO solution simultaneously inactivates viral particles in the air (based on published academic research). Our own research on the efficacy of our PCO solution has been limited to bacterial testing. We need data to ensure that we only make claims that can be backed by data.
