The Hunter 30540 PermaLife 540 Air Purifier features a new contemporary design and a permanent air filter, so you never have to replace your filter again! The Perma-Life permanent cleanable filter effectively captures 99.5% of all airborne particles as small as 0.5 microns in size that pass through the filter (such as dust, smoke, pollen, pet dander, and other irritating allergens). An advanced activated carbon prefilter reduces cooking, tobacco and pet odors while also capturing larger dust particles, lint and pet hair from dirty air. A separately controlled ionizer distributes negative ions throughout the room to speed up the cleaning process while freshening the air. Effective design exhausts clean, purified air back into the room from the top of the unit to avoid disturbing settled particles.
