"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."

"Can attest to MUCH less sickness and allergy issues since we’ve had them (~3 years)."

"it's not worth paying extra for the Wi-Fi capability because it doesn't work correctly."
Air doctor and Austin Air. I need the activated charcoal filters with a HEPA filter because of VOCS.
r/MCAS • Best air purifier ->We use an airdoctor in our living room/kitchen area + a big room dehumidifier that runs on auto. We also run a smaller airdoctor and dehumidifier in our master bedroom + bathroom. They’ve worked great for us in our house
r/ToxicMoldExposure • Air purifiers you swear by? ->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.
r/moderatelygranolamoms • What is the best HEPA home air purifier that's actually worked well in your opinion? ->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.
r/AirPurifiers • Does your air purifier really remove odors? ->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.
r/moderatelygranolamoms • What's the best quality air purifier for home you've ever used? Have you found a noticeable difference? ->I absolutely love our air doctor. They have sales often. We’ve had ours for 5 years and it’s been great.
r/BuyItForLife • Home air purifier. Especially those good for people with allergies ->I like air doctor. And then winix. Not a fan of my Coway.
r/AirPurifiers • Quietest air filter that gets rid of viruses? ->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.
r/moderatelygranolamoms • Best air purifier ?? ->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.
r/Home • What's the best air purifier for home you've used? Worth it or Scam? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
