Have had the unit up and running for a couple weeks now and so far so good! I'm obsessed with watching the numbers. I got the smaller 650 ft lilac one for my bedroom suite too and it's the same. I love that you can dim the display and how quiet this runs. I'll continue to stick with Shark!

When we first plugged it in it stayed on 100 % air quality without fluctuating, so we thought there was something wrong with it. But then, we cooked a meal in the kitchen,(the unit is in the next room) And the air quality went down, the unit came in and stayed on until it was 100 % again. Highly recommend

We purchased the Shark air purifier as a replacement for one that did not perform very well. The Shark actually performs at a level that the advertisement claimed! It adjusts the level of air circulation automatically, It is super quiet and easy to maintain. We have been very happy with this purchase and would not hesitate to recommend this product to friends.

Excellent air purifier for clean air. It constantly checks the air quality and turns itself on and off when it is set to auto mode. It is also pretty quiet for the amount of air it cleans. The main hepa filter lasts for 5 years. Hopefully it doesn't cost too much when it needs to be changed. However the two side filters need to be cleaned regularly.

I bought this about a month ago. I just put it on automatic and let it go. I love this.

The air purifier works so Good I bought one for a friend who suffers from seasonal allergies.

Love it so far we bought it to help clean the air in our house we have two dogs and it works great

Love it! Very quiet, very easy to use.

Up and running very easy to get started, and I like the fact it monitors itself

Great device no more dog smell
