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
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 two air doctors and a Winix running 24s
Skip Levoit they’re Amazon junk owned by etekcity and a bunch of other Amazon-only no names. Air doctor is great, so is Alen. IMO Alen is the only actual BIFL purifier because you get a lifetime warranty for as long as you purchase authentic Alen filters (direct or retailers - just keep the receipt). My Alen 45i and 75i are excellent and insanely quiet for the amount of air they move. I highly recommend them.
Any “testing” site that relies on affiliate links is not to be trusted. Also, neither of these “testing” methodology can quantify longevity. At the end of the day, an air purifier is a filter and a fan. Sure, fresh out of the box the leviot probably performs just fine. What about 1, 2, 3, years down the line? Bearings on the fan have seized. Or Levoit intentionally stopped producing your filter size rendering your unit obsolete on purpose.
