So glad i ignored the negative reviews. Had this a few weeks now and you might not know its working but it is. I just leave it on auto and let it do its job. The biggest test was when i burned some veggies in the oven and my house immediately filled with smoke. This thing had it cleaned and smelling fresh in an hour. I check the filters and vacuum them off as needed. Sams had the best price by far. A competitor wanted over $100 more for the same unit.

I recently had my house painted, and the smell was so strong that I was concerned about the quality of the air in my home. I also was concerned about the effects of the sanding that was done. I bought this air purifier after reading the great reviews, and it has made a big difference in the air I breathe. This purifier really works! If your purifier keeps a score of 100, you are lucky. Mine fluctuates, which is a clear indication that this purifier works!

The one we got worked for 5 days the showed an E 1 error code. We called shark and they sent us a new unit. This one seem to not have errors and is not shutting off every couple hours like the original one did. Now that I have a working unit it seems good. 3 stars because the purchased unit was defective.

This a ok purifier, but it doesn’t work as well as it claims to. We put this in our basement on “auto”. It got really humid in our basement and it kicked off saying the air was at 100% purity. Then we found a spot of mold right next to it. We picked up a dehumidifier which did the trick - but I think it doesn’t do what it claims to.

We're in Southern California and purchased this when our house was smack in the middle of 3 huge wild fires. Plugged it in and after about 30 minutes air quality was at 90% . After another 20 minutes it maxed out at 96%. It now is at 100%. So far very happy with this air purifier.

Stumbled across this little jewel while shopping! Picked it up and couldn’t be happier with the purchase. Easy to set up, whisper quiet, and I love the way it makes my house smell! My house smells fresh and clean regardless of the pets and teenagers!

The best money can buy, works flawlessly, and very quiet.

It didn't work always at 100% air quality so why do I need it!

I smother without mine I keep it clean with alcohol pads an vacuum

Its been a perfect fit for our 1 bedroom apartment.
