AIRDOCTOR AD2000 for Small & Medium Rooms and Small Bedrooms. 3 Stage Filtration with Pre-Filter, UltraHEPA, Carbon/VOC

This unit works so well in my small apartment. I keep it on automatic so it adjusts to the air quality thru-out the day. It is a bit louder at the higher fan levels which tells it is working but it is not too loud or intrusive. So glad I bought it.

This is the second air doctor we own and we absolutely love it. Placed this one in my sick relative’s room and they noticed the difference immediately. It helped keep the air crisp and clean for a very sensitive nose. The size is perfect for a bedroom. Needed this one quick so we used amazon.

Great product! Replacement filters are a bit pricey, but they’re worth every penny🪙

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.

great product

I've never had any other air purifier so can't compare to other brands, but I know this one has been great for me. It takes care of any odors, reduces allergies/irritations, and makes a nice white noise sound to sleep to. I have it in my bedroom. You can turn on night mode which turns off all light indicators on it, so it doesn't bother you when trying to sleep. I can't sleep without it. I just leave it on auto-mode 24/7 in there. Haven't noticed any change to my electric bill because of it. I actually wound up buying the biggest one AirDoctor has (5000?) for our kitchen/living room (open concept). It completely gets rid of kitchen smells, which is great so our whole first floor (again open concept) doesn't get stinky from the food we cook. The big one is super quiet compared to this, barely makes any sound at all. Refrigerator is louder. But it is a lot bigger if you are comparing sizes to this one, which is more compact.

I have such bad allergies and this thing is a life savor. It is super annoying just and highly efficient. I do feel like it helps take away some of the smell from our three dogs in our carpeted rooms as well. I’ve only had it for a short time thus far, but highly recommend for anybody who has allergies seeking to improve the air quality in their house!

Got for my grandparents Christmas gift!!

The air doctor is very quiet running and does a great job of purifying the air.

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.

Works well

I’ve had it for three days and am happy with it so far. I bought it to help improve my sleep so we shall see.
