This is the second set I bought for my home. Very good air purifier. Runs really quietly.

was not to sure how to chose a good air purifier other than consumer reports and customer reviews, customer reviews were right, these air purifiers are not loud, I keep one in each bedroom and helps us remove a ton of dust from the air we breath. my severe allerges have improved.

I purchased this product because my son has really bad chronic asthma and would cough all night long! I noticed the difference instantly with using these purifiers. He no longer coughs at night or at all in the house. We have one in our room too and I wake up feeling fresh and not stuffy. The Purifiers do not make a very loud sound, but you can hear them if they are on level 2 and 3. I actually like the sound and find it realxing white noise. I would defintely recommend this!

I like the difference this product makes in a one person smoking home. It does help, however, read directions for cleaning carefully. I thought you could wipe out the collector but it is a replaceable filter.

Good product. The improved air quality in our bedroom was evidenced almost immediately. Snoring decreased and.... we had a great night's sleep. I also noticed that I didn't wake up with sinus headaches ... Unfortuantely, one of the purifiers was damaged in shipping and the product could not be replaced so... we had to return it. Customer Service was excellent in helping me to return the product. If the product is offered again on HSN I will order it.
