"Super noticeable difference ... even just the fabric pre-filters catch a lot and their appearance varies from room to room (ex. dust in the bedroom, cooking oils in the kitchen) which leads me to believe they’re working!"

"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."
"Blue air. The prefilter is washable."

"Blue air is the best of the three, also isn’t HEPA but has a static generator which bothers some people."
"Although you'll find complaints it doesn't use a "real" HEPA filter"

earnerd00 0.2Have a set of BlueAir Health Protects that I have been running for several years. Their app is horrible, but the HACS add on works pretty well. I do have an automation check from time to time they are in the correct mode (e.g night mode, display brightness, etc.). I haven’t seen anyone besides IQAir make what seems to be a superior device (in US).
EagleEyeUSofA 0.1Blueair has a small one that would fit that space for $99 on Amzn or other retailers. I have next size up and so far so good and noticeable decrease in dust. I like being able to control it and monitor its cleaning via the app. Not advocating for the company other than after doing some research I settled on them and so far am happy.
I have a Blueair for small room and can really sense a difference. I like the app as well to track purity and change settings. So many options out there though.
SpookyScaryClown 0.1Made this small flowchart for a friend who kept sneezing through spring but wouldn’t commit to buying an air purifier Step 1: Identify the enemy Is it pollen? Dust? Pet dander? The ghost of springtime past? Yes, yes, and probably yes. Step 2: Must have criteria for air purifier \- can it actually trap allergens? \- won’t sound like a jet engine in baby’s room? \- easy on maintenance? \- doesn’t cost the soul of your firstborn? (ironic but important) Step 3: I went down the rabbit hole Compared Coway vs Levoit vs Dyson vs Honeywell vs one that looked like a spaceship BUT... nothing could compare to [blueair air purifier](https://rantsreviews.com/dp-B073WJL99W) \- Covers big spaces (so your nursery + more = chill) \- HEPASilent tech is real — gets dust, mold, pollen, pet funk, all of it \- Washable pre filter = less guilt about killing the planet \- Doesn’t wheeze like a dying robot at 2am \- Design lowkey slaps too Step 4: Baby sleeps better. You sneeze less. Partner doesn’t threaten to move to the forest. Life improves. You win!!!
MysterySkanker 0.0I have tried and gotten rid of Bluair and levoit- just inadequate performance and louder than I like. I replaced them with Medify and have been very happy with the switch. If memory serves I have an ma-50 in the living room and ma-40 is each bedroom.
9ine6ix5ive 0.0I have BlueAir in all my rooms. Makes a significant difference for me.
Acceptable-Basil4377 0.0It helps a lot. I bought it due to smoke but I’m happy to get rid of cooking and dog smells. I have one from Blueair.
accountaholic26 0.0We love our blueair also. Got a dog a month ago and happy to hear from guests our house doesn’t have a dog smell.
Adorable_Dust3799 0.0I love my blueair. It's highly rated for the price, and has a cloth sleeve you wrap around the outside and toss in the wash that prefilters out the husky fluff. If your pup is smelly it's probably oily, and needs either more roll in leaves and dirt time or more frequent bathing. A simple rub with a damp cloth frequently, like daily if you're not using soap, will work wonders.
Affectionate_Bus_884 0.0I’ve been using blueair purifier. I have 5 of them a few I’ve owned for over 4 years and I love them.
Agent_03 0.0Sorry, what "air quality problems"? Can't say we've noticed any, with our 3 air purifiers running 24/7 in a one-bedroom apartment... 😉 (Both of us have pollen allergies and one of us has asthma.) That should answer your question. Seriously, buy an air purifier. Once you feel the difference you'll probably end up getting a few more. We've got two of the medium Coway models (Airmega AP-1512HH or 200M) and a smaller BlueAir. They also help with smells -- bathroom, pet, or cooking. Highly recommend the Coways because they: * Are whisper-quiet on all but the highest setting, and can auto-adjust (though we usually leave them on medium because they get loud if they kick into high). * Move a lot of air for their size * Have filters that last way longer than they're rated for (as long as you clean the prefilter) * You can turn the main light on the purifier off for use in a bedroom at night Tip: it's better to get several medium air purifiers and put one in each room or area rather than getting just one big one.
