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.

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!

Stumbled across this little jewel while shopping! Picked it up and couldn’t be happier with the purchase. Easy to set up, whisper quiet, and I love the way it makes my house smell! My house smells fresh and clean regardless of the pets and teenagers!

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?

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.

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...

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.

This Air Purifier Max was a replacement for a prior air purifier purchase that the air sensor became defective. Shark replaced my air purifier under warranty with a better HP302 model. It was received very quickly and is working Great. I highly recommend Shark products and specifically their Air Purifier Max HP302. They stand behind their products.

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. 😊

I have bought 2 of these now. They are great product. Highly disappointed though with Shark activating my warranty while the product is still waiting on pickup from the shipper. I didn't receive either of my purifiers until a good week after Shark activated my warranty. Definitely not a business practice that I would be proud of.
