Airfree is the only air purifier manufacturer that publishes full
tests clearly indicating its efficiency in tested rooms. Guaranteed
airborne microorganism reduction with Airfree as seen in the tests
section (link)
Customers should ask each air
purifier manufacturer for efficiency independent tests (full tests
like Airfree has, showing equipment testing procedures, room size,
and effective results in the room, not projections). Customers have
the right to know average airborne microorganism and mold reduction
after an air purifier is placed in the room.
