AIRDOCTOR 3500i Smart Air Purifier for Living Rooms & Bedrooms, 3-Stage Filtration with Pre-Filter, UltraHEPA, Carbon/VOC Captures Particles 100 Times Smaller Than

So far I love these. They detect smoke right away. It hits boost mode.

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.

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!

The AirDcotor 3500i I ordered came with a defective control panel (lights flashing on and off). AirDoctor customer service was prompt and very helpful in its response. They sent a replacement unit within a couple of days. New unit is great!

Works as described, did a bunch of research and ended up getting this for the office, the only improvement would be if the app allowed a weekly on off schedule allowing for change of fan speed, Would like to run this at night on 4/4 and during the day on Auto or 1/4 but as of now that's not an option without manual button pushing.
