Great unit for any room

I use the 3500 in my bedroom and run it 24/7. I have units in 4 rooms and my family has less allergy symptoms now that we have used them for an extended period of time. A few years now.

I bought the Presidents’ Day sale and got the 3500 and 2000 with WiFi and we absolutely love them and you can definitely tell a difference in the air quality!

The Air Doctor is quiet and can turn off the lights on the control. A recent visitor said he could tell the difference in the air.

Good size for open floor concept

I can’t speak to the benefits, as it’s been too soon. We know air purifiers are beneficial regardless of noticeable effects and Air Doctor has a strongly reputable brand. I got a little sales-happy and bought the wrong package, which included machines far too large for our house. For a standard house size, this was perfect for an open family room/kitchen concept. We are also happy with the smaller size for bedrooms.

Airdoctor Classic

It is beautifully designed, not too loud and works well! We live in an older house, and I used to be worried about air quality or unseen mold. It is nice to have a peace of mind, knowing the air quality is being cleaned and also that the Airdoctor lets me know the current quality of air in an easy to read way. So thankful we were finally able to get one and would highly recommend. If is worth it

Air Doctor 3500
on December 28, 2025
Posted by: Tim C.
We recently had our house repainted and some millwork done and added the AirDoctor 3500 unit into our basement. After utilizing the unit for 1 month now, we noted that the pre-filter definitely required cleaning; it was quite dusty! We have the unit set on "Auto" mode and typically runs at the lower fan speed. Occasionally, the air quality LED will turn either orange (moderate air quality) or red (poor air quality) and the fan speed ramps up accordingly until the air quality gets back to good air quality mode (blue LED light indication) and the fan speed reduces down to low.
Based on the pre-filter cleaning after 1 month, the constant monitoring of the air quality and auto-adjusting the fan speed according to the air quality, we are quite happy with the purchase of this unit and would recommend it to others!

I love that i purchased the smart machine because its noce to see the different changes to the air quality. I have 2 units and can't wait to get more next holiday season. I love that I am making healthier choices for myself and family. Air Doctor is an accepted member of the family now!
