Blueair - Pure 411 Auto

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.

I have a blue air 411a that i got for a steal. I've seen on here they can have issues later on but after a year, it's doing ok. It's pretty solid but you have to make sure to keep your home clean and dust free. I ended up switching back to a bagged vacuum and dust twice a week. An air purifier won't help if you aren't preventing dander build up too. Edit to add: i only paid $70 for it new. You'll probably want to invest in a better model that circulates air more often.

We have the 211 Max and we also have the classic 405. I have a tiny 411 in my office.

I like BlueAir because they’re quiet and I can buy after market filters in bulk for cheap. Been running a 211 (kitchen/family room) and 411 (bedroom) continuously without turning them off since 2020 and both still operate as new. The air filter taped to the back of a box fan works really well too but is very loud even on the lowest setting. I’ve used this method before I got the BlueAirs when we were dealing with real bad wildfire smoke here in California.

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!

Made 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!!!

BluAir (Swedish) is what we used in the middle east.
