Medify MA-40 Air Purifier with H13 HEPA, White
Rooms around 375 sq ft where a timer and child lock matter
Medify's MA-40 uses a one-piece pre-filter, HEPA and carbon cartridge with three speeds, sleep mode, a timer, child lock and a switchable ionizer. Medify's documents disagree on CADR, wattage, filter life and clearance, and the listing attaches the MA-40UV manual. Register within 30 days for the lifetime warranty.
