Excerpt: I use air purifier in my bedroom, which is about 200 sqft. The unit does its job quietly, and looks great. No sign of any moisture or residue from the humidifier feature, which I leave on all the time. The only drawback is that humidity level cannot be controlled.
Pros: Affordable, Attractive Design, Quiet, User friendly
Excerpt: I've hated how quickly dust accmulated on surfaces in my home. After a bad case of allergy, I decided to buy a air purifier. My main concern was the noise generated by air purifiers.
