Our air purifiers disinfects the air and surfaces throughout a room, which goes far beyond many other air purifiers. We go beyond the need of having a HEPA filter to have an effect. A 2016 study found our technology killed 99.998% of MERS coronavirus on a surface in just 4 hours. This means if a germ makes it on a surface, like a door handle, and THEN you turn on our units our technology is able to sanitize that surface.
