I read a lot of great reviews of this product, and I honestly haven't noticed a big change in my rooms air quality. When walking back in from the outdoors I don't notice any difference in the air freshness. Aside from that, the machine is very quiet- however after several days of use my purifier started to make a low whining noise. I may have to contact customer service.
Wonderful Air Purifier for allergy sufferers like me!! Turn it to 1 and you hardly h AR it, but I have it on 2 during the day and 3 at night to help me breathe and sleep!
