I bought this and couldnt be happier with it. The sense IQ system seems to work very well. Glad I purchased this and Sams had the best value.

Bought two about a month and they are life changing. We have four dogs and the dust and odor have dissipated. So happy with these.

It is light enough to move it around for whatever location you need. I wish that the cord was a little longer.

I love it. It's only been on high a couple times to remove odors after frying food otherwise nice n quiet

I am enjoying the air purifier for several reasons; very quiet whe. It is on, shuts off automatically, no as much dust or odors, totally happy.

WOW such a great filtration system! Love it. Shark always make a great product. While home filled with Shark Products.

I got my never change air purifier for 1450 sq ft… about a month ago, and can tell a big difference in my home.

I like the first one so much I bought a second one. Now my entire house is cleaner and smells better.

I bought one now have 3. They seem to be doing the job! I had a damaged screen and they replaced it in days.

I've had this for a couple of weeks, very quiet and efficient. Seams to be doing a great job. Going to get the smaller unit for my bedroom.
