Blueair - 311 (Non-Auto)

Blue Air is great. The nice thing is most of their residential models offer a washable outer layer and the box includes a second so you can wash one while using the other. This helps catch a lot of big stuff and I change the inner filter only annually. OP - no purifier removes all dust. Cleaning the source of dust is always the most effective. Still, an air purifier, especially oversized for the room and run at a good speed (I do max overnight and just a tad slower in the day) helps get the remainder.

I have BlueAir purifiers. We bought them after I tested positive for mold exposure. I’m pretty sure mine are the 311 model, though it does look like they’ve released newer ones. At the time we did a bunch of research and these were the best on the market at that price point. But that was around 2020/2021 I think.

You’ll typically see the same top-rated models across Wirecutter, Consumer Reports, and Tech Gear Lab: the BlueAir Blue Pure 311i+ Max, Coway Airmega 1512HH, and Winix 5500. The best choice probably depends on the size of the space you’re trying to cover. For my downstairs rooms, I went with two BlueAir units (the 311 and 211 models). BlueAir offers a 25% discount for teachers, military, police, and possibly firefighters (can’t recall for sure), available in both the U.S. and Canada. They also offer a 15% discount on filter replacements if you sign up for a 6-, 9-, or 12-month subscription. For my upstairs office/bedroom—since it’s a smaller space—I went with the Coway Airmega 1512HH and have been happy with it.

A 311, a 211, and a 7470. It's best to size up and run on low (auto). The other benefit is the larger ones tend to be quieter.

Just got a 311 and can confirm my cat has scratched it a few times.

I mean.... I mentioned the part about them having no reviews and being at a sketchily low price point of 1/2 to 2/3 the cost of everyone else. There are really only a handful of air purifier brands that have demonstrated reliability, affordability, and effectiveness over several years, and don't dabble in post-apocalyptic/steampunk decor -- coway, levoit, blue air, winix. If you want to pay more, there's iq air, alen air, and a few others. For $110, you could have bought a blue air 511 and almost a 411, a levoit 300, almost a Levoit Vital 100s, or a Winix a231. The winix 5500, the coway 1512, levoit vital 200, and the blueair 311 are all at this CADR, but for closer to $200.

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!!!
