So far so good. And I'ma heavy smoker and this has cleared the air!

[This review was collected as part of a promotion.] I have HORRIBLE allergies to dust and it is only getting worse as I get older. I never realize how much dust, dander and dog hair lingers in the air until I started regularly using this air purifier. I vacuum regularly and dust the house to try to maintain it and limit the allergens but this purifier still collects all the things you can't see in the air. I have noticed IMMENSE relief especially during allergy season. And despite all of the use we've gotten out of this our filter hasn't even needed replacing yet. It is absolutely incredible to see how much stuff the filter collects! I am a big fan of the odor eliminating disc- it emits a very mild clean scent that is not at all “perfume-y”. Another amazing feature is that this purifier has a child lock- so your child can't touch the buttons to change settings I LOVE this purifier and I have recommended it to everybody in my life but especially to those tackling allergies!

Barely pushes the air. Now, after a years use, it reads 0% even with a brand new filter. It's junk!!

Expensive junk. Changed filter every 60 days, stopped working after owning for 11 months. Buy Levoit instead

The only thing it does is raise your electric bill.

Absolutely love it .. helped with a small house with several pets ,

I replaced older unit (HC501) .. I am happy with SHARK !! I own lot of there household products !!! Will buy from again !! Great service !!

I'm very happy with my Shark Air Purifier. My purifier works great as stated and keeps the air quality in my rooms fresh and clean.

[This review was collected as part of a promotion.] I’ve got a household with several kids and several animals. Needless to say we have a lot floating around in the air. This air purifier has been excellent right out of the box. Setup was incredibly easy and the user interface is easy to understand. I put mine on eco mode/auto mode and haven’t touched it sense. The only thing I’ve done is check the filter, more out of curiosity than anything else. I was shocked to see the amount of animal hair this has sucked up. In the beginning I wasn’t sure how much of the house this purifier was using but I was a believer after cooking dinner in my kitchen that is on the other side of the house. Shortly after I put bacon in the oven I could hear the purifier kick on and start cleaning the air. Overall I’m very happy with this purifier and how well it works.

[This review was collected as part of a promotion.] This air purifier was so easy to put together. The filter and the air freshener cartridge went in so well. The scent is mild and is not overpowering. It blew just the right amount of scent into the air. The touch screen is nice as well.
