Seems to work great....for a week

Broke after 5 days, making a horrendous squealing noise whenever running. Called for support and they couldn't replace it for a few weeks, called back and they still cannot replace it. I'll be honest I'm getting pretty mad at the whole ordeal.

WORKS AMAZING

Absolutely Amazing. Works Great and would recommend. I have 2 air purifiers and live with one dog. Both are fantastic. I don't understand why the majority of negative feedback is from largely, Female Customers.

Not sure about the accuracy and no odor control.

This sensor did nothing when I sprayed cleaner or air freshener near it. Still showed 199 percent clean air. It did react to blowing smoke into it. The air freshener pack smell is not noticeable unless I have my nose right at it. I’m not sure it works well as animal smells are not cleaned. The carbon should be cleaning animal smells. My blue air one removes odors whereas this shark one doesn’t seem to. I do like the size and quietness of it. My house is less than 1400 sq ft so it should be cleaning my whole house but it doesn’t seem to be fresh even though the air quality shows 100 percent.
No, I would not recommend this to a friend.

Very pleased with this air purifier! Easy to get it going. Very quiet. Notice my husband’s sneezing has slowed, so I feel this has helped with the air.
I would recommend this to a friend!

Ship time was amazing does exactly as it says it would do is super silent efficient and definitely cleans the air for me! I’m going through a severe allergen problem currently and having to turn my house upside down and this purifier has been my best friend through all of it:)
