Photocatalytic Oxidation (PCO) uses UV energy as a catalyst to turn moisture in the air into active purifying products. Working in conjunction with the other parts of your Active HEPA+ Room unit, it's proven to inactivate 99.98% of the virus that causes COVID-19.*
Over time your PCO Cell will become worn and less effective. Replacing it will help maintain the pureAir active air purification experience, providing continuously clean air for your space and everyone in it.
*Laboratory tests prove to inactivate 99.98% of SARS-CoV-2 in the air within 10 air exchanges in a controlled environment.
