I hope it lasts
on July 25, 2024

This is the third one I’ve had bc the other two just stopped working. One stopped after three months, the second after 4 months. I live alone, I got it , plugged them in and turned them on.
They were never bothered or damaged. They both just stopped working. I’ve only had this one for about a month.
Hopefully it will make it to its first filter change.
It seems good when it works . So I’m not sure how to rate this one . Rating is based on what seems like poor quality for an expensive product and being told that if another one breaks, I won’t be given a third replacement . Even if it’s within the warranty date. As if it’s my fault that the products are extra defective.
On a positive note, both replacements came promptly.

I recently switched to air doctors when moving apartments in Florida. These units have really helped me survive new builds in Florida. They are great machines.

Less Dust!!!
on November 20, 2025
Posted by: Bryan B.
The Air Doctor 3500 has been one of the few appliances I bought that made an immediate, noticeable difference. The air in my house feels cleaner, lighter, and the dust buildup has dropped a lot. I like that it adjusts on its own and usually stays pretty quiet. When it kicks up to a higher speed you can hear it, but it’s worth it for how well it works. Overall, I’m really happy with it and would definitely buy it again.

Nice overall air cleaner
on February 16, 2025

I like most everything about this air cleaner.
Air doctor functions well, and has good data behind its product.
My one wish to make it even better for our environment, and consumer's pocketbooks, would be reusable, cleansable filters.

It was a hard decision to spend that much money but we are very happy. Wish you would have done it sooner. It really keeps the cat litter dust down.
