Have it running for week now and it is very quiet you don't even know it's running. Much quieter than the other air purifier's I have running in bedrooms.

This is the best air purifier that I have ever had. It is very easy to assemble. It works like a charm with no issues. I highly recommend this to anyone that is looking. You will not be disappointed.

I bought this last month. I've been enjoying the cleaner air quality. Very easy to rinse off the outside filters, and, put them back in. No dust particles when the sun shines through the windows. Satisfied customer.

It's been going great. I can see it actively working as I do things like deep cleaning and cooking. It's peace of mind for someone who has cats and allergies to said cats.

Good price. Air quality shows100% most of the time. Not sure how accurate this is. This is our second one. Shark replaced the first with no questions. Easy to work with. A little noisy but doesn't disturb our sleep.

We have only had the Shark Air Purifier a couple of weeks but very happy with it so far. The air seems much cleaner and fresher with the air purifier.

We purchased this about 3 weeks ago and it has work very well. We have a large Lab that is inside and the order has went down amazingly well. My husband has asthma and it has helped him too!

Shark air purifiers are excellent! I have 2 others that have been awesome the past 2 yrs with 4 dogs in the house and hope the never-change purifier performs just as well!

[This review was collected as part of a promotion.] This device works so well in our basement. We recently finished our basement and I knew this needed to go down there to get to work. It is very quiet but works great in that space.

I bought this 2 weeks ago and it has been fantastic! I have 2 dogs and you would think I didn't have any. My living room still smells fresh and clean! I'm definitely getting another one for the basement.
