AD5500 Smart App Air Purifier. Cleans Whole Home, XL Rooms Up to 4172 ft2. Removes Smoke, Dust, Pet Hair, Odors, Pollen. Hospital-Grade UltraHEPA, Premium Carbon Filtration

We live in a well built living space in a colder climate and can't open windows a good part of the year so we wanted to be sure our air quality was optimum. From day one of plugging this in the air has felt and smelled cleaner. It is so sensitive that a little hairspray drifting from the bathroom, or opening the oven while baking pies, kicks the unit automatically into high mode and instantly clears the air. A small price to pay for amazingly healthy, indoor air!

The best air filter I have ever bought. Got it to control odor from patient wounds. Works great on even the worst odors.

Works great! Keeping the dust down in the house!

Purchased this less than 2 years ago and it worked fine for the first year then it disconnected from WiFi and I’m not able to connect it again. I’ve tried different WiFi and it still doesn’t work. I’ve contacted customer service and they were no help, they tried blaming everything but the unit itself, spent hours on the phone and still couldn’t get it resolved. I believe it takes a new WiFi module but they won’t send me a replacement. It’s disappointing to spend over $1000. and it only works for a year, not to mention the replacement filters are unaffordable, $574. for a 2 year supply. Can’t in good faith recommend this company.

Works well,

Works as advertised. Super quiet once air is clean.

Works beautifully. Removes food odors and keeps excellent air quality. Before purchase, would wake up w/ nose stuffed up. Now, nose and throat are clear--no more blowing my nose every morning. Love it! Worth every penny!

Not worth it at all - does not do what it is supposed to do! Please read on for detailed instances: Purchased this to work in conjunction with a Dyson model we have in our bedroom for the main part of our house. At 1st setup it ran in the red(Bad quality) for about an hour or 2 - went to bed and by morning it was blue(Good quality). Stayed in the blue for the next 2 weeks. Thought it was doing its job until I decided to sweep and vacuum down our wood tongue and groove cathedral ceiling and walls. With dust literally falling on the unit it never turned on to orange or red - just stayed blue while our Dyson was on level 10 Strike two was when, me being an idiot and not shutting the door on the woodstove correctly, had smoke in the house. Enough smoke that the smoke alarms were going off and the Dyson behind a closed door was screaming on level 10 while the Air Doctor just putted along the color blue happy as can be. And fyi, the Dyson was at the other end of the house while the Air Doctor was about 6 feet away from the woodstove. There is no excuse for it to not clean the air at this point. Strike three was customer service. They had me open a door on the side of the unit, light a match and blow it out into the sensor behind the door while doing it on video to send in to them. I send 2 videos in. The 1st time nothing happened at all - color was blue so I tried it again. The 2nd time it actually went orange for about 5-8 seconds and went right back to blue. I got confirmation of the email and videos from Air Doctor stating that someone will be in touch in 48-72 hours. Never did hear back from them with the exception of the open case I had being closed because I never responded or sent in any videos even though I have an email stating I did and to wait for a response. To conclude - It does not clean the air as it should and customer service seems to just give you the run around.
