AirDoctor - AirDoctor 3500i

I have an air doctor 3500 and it seems to work fine; haven’t tried the ionizing function. I also have my LEVOIT still and it is still working. I contacted them to ask if they are HEPA and they said they do have HEPA grade…so…not sure what that situation is with them but the purifier does work, can see the dust it sucks in on the pre filter. I’m still considering also getting a Wellis to target mold/mildew/viruses but I’m hesitant for the same reason you mentioned. I’m looking for actual customer or really any feedback from anyone but what I have found is very limited and from other countries. How has it been for you? Do you notice any difference at all with it? I did find some info about hydroxyl radical production technology. Not particularly Wellis, but what they claim to use. There were some things that came up saying it is safe, but others saying it can interact with things and create different unsafe vocs, like formaldehyde. That’s what has kept me from trying it so far, but trying to find more information on Wellis and that type of technology.

i love our AirDoctor! the units go on sale occasionally but the filters unfortunately never do. it works extremely well for smoke, cooking odors, regular dust/particulates. i’ve had mine for 3 years and have had zero issues with it. you can vacuum the first filter ever month (or more often if needed) and then there’s a carbon filter and hepa filter that are replaced at different intervals depending on air quality.

The best on the market imo is Austin air but it’s pricey. I will likely only buy one for my baby’s nursery. We have air doctors in our bedroom and living room, and they seem to work quite well. We had our second model stop working under warranty and they replaced it at no cost, but that is the only bad experience we have had. Our older unit is still going strong a few years in.

In my experience air purifiers do work well but they can take a little bit of time so you’ll still smell it right after your cat goes. Currently have the Air Doctor and love it. Make sure you’re using enough litter that they can bury their poos and fully changing out the litter every 30 days to help with odor control.

I have 2 air doctors and a levoit and don't notice any difference between them. If money was no option I'd probably gonwoth Austin Air or Jaspr. If budget then Levoit or Winix from Costco. Or Costco also has a Shark with a 5 year filter.

We have had the Air Doctor for about 2 years now and love it. Got us through mycotoxins, fires, living by a freeway. It has a sensor that also increases filtration when needed. We change the carbon filter 2x/year and the HEPA filter 1x/year.

airdoctor is by far the best and they are having a sale right now!

We've had an Air Doctor on our main floor for many years and its legit. crazy the amount of stuff we find in the first front filter.

Air Doctor! We have 3. Two at home and one at work. Love them. Zero complaints. Can attest to MUCH less sickness and allergy issues since we’ve had them (~3 years). Filters only need replacing every 6-12 months depending on how much stuff they’re collecting from your air. It’s honestly super gross to see the used filters BUT makes me feel good to know all of that stuff is not in our air/breathing it in! It’s even strong enough to filter out COVID and flu virus particles which was a big plus. Most of their products are under $500 and they do regular promos throughout the year too where you can get discounts off as well. Hope this helps!

Airdoctor has been really good to me
