Shark - Air Purifier 4 with Anti-Allergen Multi-Filter & Advanced Odor Lock, 1,000 sq. ft. - Charcoal Gray

Had to upgrade from my old Honeywell and this was the best thing I've done. I have a house with kid that have bad allergies and this unit does a great job. I couldn't believe it knew the air quality was bad on a high pollen day so I was able to close my windows so my girls wouldn't have a bad night. Very quiet fans is a plus also. The only complaint could be the filter placement every 6 months for 2 that i both is a little pricey.

Easy to remove the old filter and then put the new one in. Will be buying the replacement from Best Buy again.

We ordered two of these air purifiers. One for upstairs and one for downstairs. After hooking them up (super easy) and letting them run for a day, we could already tell a subtle difference. Then while cooking, the smell of burnt toast had that machine kicking into high gear! It immediately cleared the smell! Our upstairs one is located close to our dog's kennel and it works just as well. The brightness on the display can be reduced or turned off completely. Highly recommend!

Powerful and quiet operation. Can crank it up when necessary.

This air purifier is the best very easy to use and it does really work amazing enjoying air without the hassle of dust and more the remote control is easy to use and u can always use the remote or use the digital panel this air purifier got on top and is dry quiet I can feel the difference and the quality of the air the remote got many options to set it up as well the panels it got on top the filter is very easy to instal and removed when it's time to change the filter for best quality of air I leave it all the time and js energy saver so not worry about my bill at all very elegant design (got it in white) I truly recommend it if you got allergies or if you wanna breath good quality of air you should buy this one I'm glad I did buy it is one of the best thing I could buy

Quite, sleek, and works great! We have a German Shepherd that likes to sleep inside the house during warm days and our guests always curious to know how we keep our house dog and dog food odor free. This device does the job.

Amazing purifier. Just started to use it in living room. My floor plan is open to kitchen and first time I cooked immediately the purifier started to sense and clean. Buy it! As for noise, I would say it's more of a white noise sound. Does not affect or annoy us. Clean air is worth it.

We have put these to the test & they’re absolutely incredible! You will not regret investing in these air filters!! Even friends with severe cat allergies can breathe easily in our home! AMAZING!!

Just bought last week. I am back to back with the freeway, and that was the reason of the air purifier purchase. Once I plugged in the air purifier for the first time, it displayed 60%. After 30 minutes the purifier displayed 100% When cooking, the air quality drops to 45%. Once I turn off the stove burners, the air quality starts making it’s way to 100%, and the food odor start to go away. It takes 30 to 60 minutes to reach 100%, and of course it depends on your room size (sq.ft) I would recommend this: Shark - Air Purifier 4 with Anti-Allergen Multi-Filter to anyone with the same problem I have, or for any other purpose this purifier was made for.
