- Air Purifier for Home AIRDOCTOR AD2000 for Small & Medium Rooms and Small Bedrooms. 3 Stage Filtration with Pre-Filter, UltraHEPA, Carbon/VOC (AirDoctor 2000)

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.

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.

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.

This air purifier really works wonders!

Great product I should’ve bought this thing earlier. It really does purify the air the way they say it does.

We bought a new couch that had a horrible VOC smell for days. We bought this air purifier and no joke, the smell was not very noticeable the very next day. So thank you to this company for this wonderful product.

Run quietly and if obstructed in any way, the color indicator changes color. Make sure to keep clearance per the directions or it will not work as intended. I bought three of them and am happy with all of them. Be sure to buy filters when purchasing units.

These are amazing. Quiet, efficient, and filters can be vacuumed monthly. Amazing the amount of dust reduction in my home!

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!

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

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

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.
