DESC: Over time, any household room can get stuffy and dank, especially in the colder months, when windows stay shut for months on end. Anyone with respiratory allergies knows how that stuffiness, which is the result of an increase in airborne particles, can affect the mere act of breathing. Not to mention the odors. The Holmes Harmony Air Purifier can scrub those particles out of the air with a High Efficiency Particulate Air (HEPA) filter. Particles of dust, pollen, pet dander, mold spores, and even smoke larger than 2 microns are caught in the filters tiny screens. And theres an ionizing function that helps even smaller motes clump together, so theyre big enough to get filtered out. A lungful of air scrubbed by the Harmony Air Purifier feels and smells like its from a snowy mountaintop
