Enjoy the benefits of high efficiency, HEPA air filtration without the expensive HEPA replacement filter costs. Honeywell True HEPA air purifiers are the best choice for reducing airborne allergens. In fact, more doctors recommend Honeywell enviracaire air purifiers to their patients than any other brand. The True HEPA filter removes at least 99.97% of common household particles as small as 0.3 microns from the air passing through it such as dust, pollen, tobacco smoke, mold spores and cat dander. It even helps reduce viruses and bacteria. The carbon pre-filter captures larger airborne particles and helps remove common household odors. QuietCare sound reducing technology provides ultra quiet operation. The permanent HEPA filter is easy to clean - simply vacuum about twice a year (depending on use). The Intelli-Check Electronic Filter Indicator reminds you when to clean the HEPA filter and when to replace the carbon pre-filter. This model is recommended for medium size rooms up to 200 square feet.
