Filter Testing

  Whether you’re planning to or already have upgraded your filtration, we’ve verified the efficacy of both portable and permanently installed units. Particles comparable in size to the COVID-19 molecule are injected upstream of the filter. The concentration of the particles is then measured before and after the filter shows the percent effectiveness of the filter. We have provided this service to Fortune 500 companies in major metropolitan areas including New York City, Chicago, and Washington D.C.
