It is ok but I didn't receive a book or any information on how to use it so it's just sitting there.

So far, I like this unit very well. It is amazing how quiet it is and was easy to set up. I buying it when it was on sale made it that much 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.

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

This air purifier has helped with my allergies tremendously. Both my husband and I have stopped coughing as much and are able to sleep better.

We bought the smaller one for our bedroom, worked so well we bought the bigger one for the living room

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

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

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.

The air quality has been so much better since we started using our new Shark air purifier. Great product!
