I got this for $100 off its regular price so it’s was a good deal. Works great. Be ware of expensive filter that will need to be replaced.

Good product. At first the sensor would always read 100% which made me feel like the filter wasn't working correctly. However, after cooking in the house I could see the sensor change. After a couple days using this filter I noticed that my nose was a lot less busier than normal. In the future it would be a good improvement to add a 2nd sensor for larger stuff like dust. I would like this filter to detect and auto run based on dust as well.

Works great, the only thing I feel is we are replacing the filter more often than it says we have to.

This air purifier is a bit more complex than ones I got before, but the start-up instructions for this made it quick and simple. It's terrific that it has options for manual operation or auto-sensing so that the fans aren't on full rpm 100% of the time depending on air quality. It does manage to keep dust and pollen under control which help my allergies a lot!
The replaceable filter does feel a bit much in price, but it's peace of mind. It's definitely better that I don't have to put up with frequent sneezing/stuffy nose from whatever is brought into the house during the summer. With winter around the corner, a.k.a. Dust and Cold Season, this will be better managed.

This has been a good air purifier so far. The size fits nicely against a wall and the unit runs fairly quiet. I do sometimes question the reading I'm getting on the screen however I think my humidifier may be confusing the sensors.

This air purifier is very quiet at low speeds and kicks in as soon as it senses odors. I keep it in my kitchen, and it keeps odors to a minimum while cooking and clears the smell quickly.

Shark has done it again. I couldn’t resist the $199 price. I should’ve gotten two. It’s pretty cool to set it to auto. Very quiet and you won’t even realize that it’s on. It does the job

The auto mode is nice! It's quiet on the lower speeds but you can hear it when it goes on high. We noticed a difference in the air quality

Looks to be a good air purifier with a lot of features, and adding convenience with a remote control. It also looks very nice that would add a great decoration to your room.

This unit is amazing! Works wonderfully and reduces the amount of dust and dander you’d otherwise be breathing. Love the air quality feature too. Nice and compact!

The wife loves the sound of a fan going at night in the bedroom, and this fits the bill. It amazing that if this is set to auto, and somebody starts cooking in the kitchen, this will detect the added air impuritites and start cleaning the air. When you change the filter, it's amazing what it collects.

Works perfect! At levels 1-3 pretty quiet, level 4 is a little on the loud side but only needed for bacon/other air quality emergencies so it works!

Decided to buy this air purifier because we had started looking for one and found a good deal at Best Buy. Works great, not noisy unless turned on high which we haven’t needed yet. Easy to use and looks nice

I got this on sale. We put it in our bedroom first. Our bedroom is quite big. I was a little skeptical because it immediately said 94 or 95%. When we have dogs and cats and vape. But when I blew Vape smoke towards it it automatically went down. I do vacuum and clean a lot. But I feel is on going to give it a little more time before I am totally sold on it. If I had paid full price I'm not sure I would think it was worth it. I brought it downstairs today it again is reading good levels. Which I just find odd. The real test will be when my brother-in-law Cooks fish which is what I really wanted it for. I will update when he does that if it actually helps. If it does I plan on buying another one.
