Blueair - 311 Auto

I own a Coway Airmega, BlueAir 311 Auto, and a Dyson PureCool. Coway is for the main living room/kitchen, BlueAir for kids rom, and Dyson for our bedroom. Overall the Coway is my favorite. It’s a beast and has a low cost of annual maintenance. Strongly recommend.

I have a Blue Air 311 Auto and I've opted for the smoke block filters (just a warning, those genuine filters are pricey), but it has been worth every penny. It has been on constantly for 3 years now without any issue. I have lived in two major cities and can't say enough good things. 100% worth the investment. The one thing to pay attention to when selecting a model is what square footage you want covered (for Blue Air I think the larger numbers correlate with more square footage that they cover).

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.

I have a feeling that only the largest, most expensive purifiers will help and you will need more than one for 1500sqft. And they won't clear the stench immediately. Marijuana nowadays is very intensely stinky and seems to stick and linger. I'm reading a lot of posts about this problem and everyone is in apartments. I'm in a house with a backyard separating my two open windows from any neighbors and that stuff STILL gets trapped inside my house. I am woken early in the morning by it, like a skunk just sprayed in my backyard. And it lingers for hours. I don't know how that's even possible. I'm not even sure which neighbor is doing it. I can't hear or see anything. That's how far away they are. Since I'm in a house I can prevent the problem by closing my windows quickly at the first whiff of skunkiness. I would lose my mind if I could still smell it with all the windows closed. I have a BlueAir 311 and it does nothing at all for odors. Not sure if it does anything helpful. I would like to see laws banning outdoor smoking. That's the solution. And laws banning scented dryer sheets. Those smell like poison and engulf entire neighborhoods.

I have a Blueair 311 and really like it. Very quiet than other brands ive had, including Levoit 

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.

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