It seems to have very sensitive and good performance. It has an air purifying effect.

I now have 3 of these, they automatically adjust based on the quality of the air.

DOESENT WORK THIS IS THE REPLACEMENT OF THE ORIGINAL ONE THAT DIDNT WORK

Was not happy at all did everything right and still wasn't working properly

So far I don’t know if I like it. I’m not sure it is working properly! Started out fine. But I’m going to check to see if it’s working.

Works well, reduces cooking and pet odors . I am disappointed that the price came down $50 about 3 weeks after I purchased it but that’s my luck .

[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 have a cat, and I am a smoker. But it does to make the air quality better. Time will tell but it appears to be doing a great job so far. Shark always makes a great product; I own a couple of Shark Product & they work great. Thanks again

I sell appliances and have a Dyson PH04 purifier which is great. But Shark is also a Great purifier highly recommend! I would like to know where to get the replacement odor cartridge .

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.
