AIRDOCTOR AD3500 Smart App Air Purifier. Cleans Bedrooms, Large Rooms Up to 2,520 ft2. Removes Smoke, Dust, Pet Hair, Odors, Pollen. Hospital-Grade UltraHEPA, Premium Carbon Filtration

Definitely waste a lot of money on other air purifiers but this one I got my moneys worth had it for a year now it still works just like the day I bought it. I have the one with the app for my phone. Gives me the most updated information. The amount of hair and dust from pets that floats around in the air it grabs it all my house smells fresh and clean.

Works as advertised! It's a luxury expense, but it's obvious that it's pulling our particulates from the air. Not sure the smart features are worth the extra dollars, but I do like the control I have from my phone and getting updates when poor air quality is detected. Not looking forward to replacing filters in this unit due to the price. The unit is smaller than I expected it to be and much quieter than other air purifiers I've used with success. Would probably buy another one but without smart features.

Excellent! Has improved the air quality in our home. Has been especially helpful with dog dander from 2 dogs. I plan on buying an additional one for the bedroom.

Doing a remodel in our home and staying one one room and bath. The auditor has kept all the dust out and even fumes. Very pleased.

Don’t let the 4 star confuse you, because I do LOVE my air doctor. Definitely not the cheapest, but it does amazing at improving the air quality in our home. We have a golden retriever as well for reference. This thing sits in our living room and kicks on anytime we are cooking. It clears the air relatively quickly, and I have even noticed how much better I feel downstairs vs how scratchy my throat is after being upstairs without it for over an hour. I am taking off a star because it is quite loud when it’s on the highest setting (which kicks on a lot after we prep breakfast on dinner.. as it should). I also purchased the blue air purifier for comparison and noticed that it is SO much quieter, however it does not clear the smells as quickly and is reported not to be able to distinguish particles as small as viruses like the air doctor. Highly recommend if you can get past the noise factor!

It seems to work quite well. What I really like is how quiet it is

This unit is very good value. Got it on sale. Unit can sense any cooking odors within minutes. Have unit in bedroom and it turns to high setting almost instantly when cooking. My wife has breathing device for night and this really helps. When on low setting can hardy notice the sound

Love it!!

So far I love these. They actually detect smoke in the air. Works great. Best air purifier I've ever owned.

Stopped working after 4 months. Seller did not offer a warranty. I called the head office and an investigation on the seller has commenced. The company only has an email address to reach out to them.
