"They're incredible and the best thing is that they have this washable cloth sleeve (pre filter) that goes over the entire intake which happens to wrap all the way around. ... It does such a good job that the actual internal filter stays significantly cleaner and doesn't need to be cleaned or changed as often. ... It's a game changer."
"Blueair imo because they have washable prefilters, and pet hair and dander is large and honestly doesn't need HEPA filters to clear it out the way, say, smoke does."
"The outer pre-filters do put up a lot of dust and I can throw them in the wash."

"Blue air is the best of the three, also isn’t HEPA but has a static generator which bothers some people."

"I don’t like they have an ionizer that you can’t disable. ... Ionizers create ozone, and when ozone reacts with different molecules it creates all kinds of new compounds that can’t be predicted."

"OTOH, the two Blueair purifiers are on all the time and we have ***not*** noticed a decrease in the rate at which dust accumulates on the woodwork in the house."

Levoit Core 300 or Blueair 411i. They're both super quiet, lights can be turned off, perfect for dust in a bedroom.
r/BuyItForLife • Good air purifier to use against alergens/dust. ->We are in the same boat - we have two dogs in a small house and I’m due next week. We’ve had a Blue Air purifier with the pet dander & dust filter and it seems to be working well - we have one big unit (i think the product is 211i Max) down in our first floor that was gifted to us from my in-laws two summers ago when wildfire smoke was really bad. We just bought the smaller version (411i Max) with the same filter for our bedroom. We had a purifier for our bedroom from Home Depot for a few years but it was not cutting it. The Blue Air’s are kind of pricey, but the filter life lasts a long time and I like that I can control them from my phone (fan speed, see how dirty the filter is, etc.) Also like that they’re not an eye sore and you can pick the color of the fabric that goes over the unit. Looks like they’re running some sales right now too! (https://www.blueair.com/us/shop/air-purifiers)
r/BabyBumps • Are there any Good Air Purifiers for Pets on the market today? ->We use the Blueair 311i max and 411i max, you can order a slightly more expensive smokeblock filter for them specifically made to filter out the particles in wildfire smoke. These units will also give you a readout on your phone to monitor the air quality in your home.
r/vancouver • What air purifiers are best for forest fire smoke? In a 400sq ft room? ->I have a 411i MAX in my bedroom and 211i MAX in the living/kitchen/dining area. I purchased directly from BlueAir and have been happy enough with them. I didn’t really read reviews beforehand but am happy to answer questions you have.
r/Costco • Anyone have the two pack blue air purifiers? ->I use two different ones: Winx C545 (Costco) and Blueair 411 (Amazon). The latter one served as the forced-air exhaust on my old DIY litter box.
r/litterrobot • Air purifier for Litter Robot ->Plus one for this. I have two blue air 411s in bedrooms and they are very good and new filters aren’t too expensive either.
r/BuyFromEU • Are there European air purifiers you recommend? ->We have the 211 Max and we also have the classic 405. I have a tiny 411 in my office.
r/NewParents • Air purifiers in the nursery: best one? are they really necessary? ->The only thing that will stop dust from your PC is you cleaning your PC and cleaning your house. Regularly. I have a 411 for over a year, and it's been fine. Edit for clarity
r/AirPurifiers • Blue Air 511 - Buyers Regret ->I have a Blue Air 411. I was waking up with a sore throat for over a year. Had the idea to run the purifier in our room at night and my sore throat is gone!
r/homeowners • What are the best air purifiers for home currently? Do you notice any difference when using them? ->BlueAir Max Pure
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->Love my blueair - i have 3
