Product details:
This air cleaner stops allergy & asthma causing pet hair in huge homes & big offices as well as small spaces with best high volume ionic HEPA & carbon filter scrubbers you can buy. A lot of HEPA air purifiers do a fair job of removing the majority of allergy and illness-causing particles, but most HEPA filters do not remove the smallest particles (bacteria, mold spores, pet dander, viruses, etc) around 0.1 microns that cause chronic allergies, fatigue, poor sleep, and other health problems. And, most HEPA air cleaners are not quiet enough to be used in sleeping, nurseries, or other areas where quiet air purification is needed. The Blueair 550E HEPASilent room air purifier is ultra-quiet, so you get the cleanest air possible and maximum allergy reduction--without the usual air purifier noise. Its so quiet that many people buy this air cleaner for their bedrooms, nurseries, and offices.
