So quiet. [MAKE SURE TO REMOVE ALL PLASTIC FROM FILTER PARTS OR IT WON'T BE!] My morning sinus issues improved after only one night of running the unit. After 4 nights, I woke with almost no sinus "goop" at all. It's definitely larger than I wanted, and it reminds me of a paper shredder, but those are my only complaints. My nightstand is 21" x 22", for perspective (photo). I wanted a table top unit, but I couldn't find one that was rated for more than ~150 sq ft. I think this unit gives a great bang for your buck, and I highly recommend it.

So nice, I bought it twice!!
We have 3 dogs a spacious yard and a meek, 900 square feet of living space.
Automatically comes with more dust than the norm. Add our car port being about 100 feet from the retaining wall of US 101. Equals more dust...
First purchase was Cyber Monday. My family I and were so pleased, there was absolutely no hesitation purchasing our second unit at regular price, just a few days later.
It's becoming my favorite topic of conversation lately. HIGHLY recommended!

My new apartment has this weird smell which bothers me a lot. This makes me decide to buy this purifier. The installation is very easy and you just need to remove the two filters (one white and one black) from the plastic bags. After 24 hours I can tell a difference upon entry. I have been using this after one week now and my apartment does not smell bad any more! It does its job! I am now glad that I bought this purifier and and it is indeed a good deal compared with purifiers of the approximate size.
