This a ok purifier, but it doesn’t work as well as it claims to. We put this in our basement on “auto”. It got really humid in our basement and it kicked off saying the air was at 100% purity. Then we found a spot of mold right next to it. We picked up a dehumidifier which did the trick - but I think it doesn’t do what it claims to.

We live in an older farm house so everything is always dusty. I bought this in hopes of eliminating some of the dust particles out of the air. After several days of running I am getting very little dust captured in the filters, but I am getting a lot of dust collecting on the inside of the fins that cover the blower fan output. What this tells me is the dust is being sucked into the filter housing, somehow bypassing or getting around the filters, and finally collecting or getting stuck on the vent fins just prior to exiting. If dust is getting past the filters, then is it really filtering anything?

So glad i ignored the negative reviews. Had this a few weeks now and you might not know its working but it is. I just leave it on auto and let it do its job. The biggest test was when i burned some veggies in the oven and my house immediately filled with smoke. This thing had it cleaned and smelling fresh in an hour. I check the filters and vacuum them off as needed. Sams had the best price by far. A competitor wanted over $100 more for the same unit.

Been using it for about a month now. Definitely a good decision ! I use this for our kitchen family room area. Let run for most of the day, really cleans up the air. The led usually stays at 100. Just to satisfy my curiosity, I took it to the garage. The led circle started doing its thing, stopped at 46. I was amazed. I didn't to tell The Wife, that would give her solid proof that it's time to clean the garage...

The one we got worked for 5 days the showed an E 1 error code. We called shark and they sent us a new unit. This one seem to not have errors and is not shutting off every couple hours like the original one did. Now that I have a working unit it seems good. 3 stars because the purchased unit was defective.

I recently had my house painted, and the smell was so strong that I was concerned about the quality of the air in my home. I also was concerned about the effects of the sanding that was done. I bought this air purifier after reading the great reviews, and it has made a big difference in the air I breathe. This purifier really works! If your purifier keeps a score of 100, you are lucky. Mine fluctuates, which is a clear indication that this purifier works!

We're in Southern California and purchased this when our house was smack in the middle of 3 huge wild fires. Plugged it in and after about 30 minutes air quality was at 90% . After another 20 minutes it maxed out at 96%. It now is at 100%. So far very happy with this air purifier.

[This review was collected as part of a promotion.] This unit is impressive. It is completely automatic and has a helpful screen that tells you how clean your air is. It works until your air is 100%. In my house I have seen a huge difference, we have two cats and three kids and it has never smelled better and fresher. On top of that the filter barely needs to be changed.

I love this Shark air purifier!! It is so quiet you don't even hear it running and I love that I don't have to worry about changing a filter. It keeps my living room and kitchen air clean and smells fresh all day. I named it R2D2 because of the shape. 😊

[This review was collected as part of a promotion.] This is one amazing machine. I felt the difference in a little more than a day. I have terrible allergies for dust, etc. and this helped right away. I am so grateful for this. I had tried others before, but this surpassed all.
