Although HEPA filters were invented in the 1950s, devices that use them have experienced an explosion in popularity in recent years. In response, the market has been filled with thousands of products claiming to use HEPA filters without factory testing confirming this. In a new online resource, air filtration experts from Camfil USA explain how HEPA filters work and how to determine which air purifiers and other products actually deliver HEPA-level filtration.

“Many so-called HEPA air filters on the market may not offer this level of protection or even close to it, as there is no evidence that the filter will perform at HEPA levels,” said Mark Davidson, Manager of Marketing and Technical Materials at Camfil US FROM AMERICA. “As a result, many air purifiers and air purifiers that advertise HEPA filters do not actually provide the protection against airborne viruses that consumers paid for when purchasing these devices.”

The resource includes:

• What is a HEPA filter?

• How do HEPA filters work?

• What does “Most Pervasive Particle Size” (MPPS) mean?

• How do you know if a HEPA filter is genuine?
