Review: It Works! - Super quiet and sensitive to pollution. Color changes and fan increases when I bring clothing with minor sawdust or drywall dust into the room even though it is a few feet away!
Review: Update - new unit works like a charm - Update: I am stunned by the amazing customer service. They replaced the unit and it works beautifully. Very quiet. It immediately picked up on the smoke and revved up the fan speed. We have prescribed burns in the area. It is so appreciated when in an area with such bad air quality. They went above and beyond. I would absolutely buy from them again. Many thanks - you are making a difference in this person's health. So far I have noticed: It is very loud, much louder than they stated. Can't hear the tv over the fan even though unit is a long way off in another room. It does not remove cooking odors. The light remains blue even with smoke, so the sensor doesn't seem to work. I have to use the manual fan speed, since the auto mode is always on too low, even when there is smoke in the air. My AirOasis works much better and quieter. I have to say, I would not buy this brand again. I'm holding out hope it is filtering mold out of the air. Time will tell.

### ⭐⭐⭐⭐⭐ Very Quite
*by S***O on 30 January 2025*

Love the AirDoctor 2000. Is very quiet and the air is noticeably fresher. We put in our son’s bedroom and he is very fussy with noise when he is trying to go to sleep. This machine is not loud and you can mute the blue light at night. Going to purchase a couple more for other bedrooms.
