Recommended for rooms up to 180 sq ft, and with replacement filter HAPF30PDQ-U.

Amazon Review

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 there's an ionizing function that helps even smaller motes clump together, so they're big enough to get filtered out. A lungful of air scrubbed by the Harmony Air Purifier feels and smells like it's from a snowy mountaintop.

The Harmony Air Purifier is designed for a 180-square-foot room, or about 12 by 15 feet. The unit is a slim oval tower of ivory plastic less than three feet tall, easy to place in an unobtrusive corner of the room. There are two control knobs--one for the three power settings, and one to turn the ionizer on or off. An indicator light lets you know when the filter needs changing.

The outside of the unit can be cleaned with a damp cloth. The air inlet grill can be washed in hot soapy water (not dishwasher-safe); it should be completely dry before being replaced into the unit. The top air outlet can be swept clean with a small, soft brush. The air purifier measures 26-1/2 by 9-1/2 by 6-1/2 inches. Holmes products include a 3-year warranty and come with detailed operating instructions. --Garland Withers
