"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."


"Love the washable outside fabric filter"


"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."

Exact same here. It was so good that we got 3. The filters are a little pricy but rock solid design and very reliable.

r/homeownersBest Air Purifier for Home Use? Need Recommendations pls!
11 months ago

I have 2, after spending too much time picking them out, love them both. Silent functioning, strong de-smelling (we don’t have a kitchen hood and cook a lot) and visual fit in our rooms were the important considerations. Blue Air Blue Pure 211+ has been working without a hitch for four and half years now. Got it when the smoke from fires was unbearable around here. Love the washable outside fabric filter, and changing the inner (expensive but not often needed) inner filter is a piece of cake. https://www.blueair.com/us/shop/air-purifiers (They don’t seem to make this same model but plenty other choices) https://cowaymega.com/products/airmega-230 has been working beautifully about a year now. Easy to clean prefilter, love the functionality and ability to turn the light indicators off. I don’t get sick any more.

Blueair 211+ non auto. Been using them for seven years and still going strong. They have truly changed my life for the better.

I second the Blueair purifiers. I have the 211+ non auto in my living room and the smaller versions in my bedrooms. I've had the 211+ running for about ten years and still going strong. The smaller ones I had to replace recently. I got the table top Mini Max through Costco in a 2-pack and I regret that size. I'll get the smaller standing 411 ones again next time.

r/bernesemountaindogsAnyone use air purifiers?
9 months ago

We have 3 air purifiers (one in the main space, one in my bedroom, one in the basement)- necessary when you have a Berner and 6 cats lol. The big main spaces ones are blueair blue 211+s- they're amazing, the covers are machine washable and they're super quiet. My room one is just a little one from ikea lol- also works great, but is definitely for a small room only.

r/vancouverWhat air purifiers are best for forest fire smoke? In a 400sq ft room?
6 months ago

I use a blue air 211+ filter and love it. For some reason it also feels like the air cools down, but I know that's just because it's moving the air around the room. I've had mine for 4 years now? Replacement filters are a bit pricey, but it really helps the air in the old building I live in.

r/AirPurifiersFound a blue air Classic 500/600
6 months ago

I have one and think it is worth $50. I got it at Blueair and it was on sale for $300 or so off. It's a very expensive air purifier and three filters are need. If you want odor control, too, you must get the [Classic 500/600 Series DualProtection Filter](https://www.blueair.com/products/500-600-series-dualprotection), as opposed to the filters that just clean the room. They range from $120-150 for three, depending on where you buy them online. The Blueair website even has a subscription plan where you get a discount for subscribing. I'm using it in a foyer which is connected to a living room and dining room, and it works fine. The foyer is right off the breakfast nook and kitchen, and it does an excellent job eliminating cooking smells that drift into the foyer and can travel upstairs. The first two speeds are quiet, but the third highest speed is very, very loud. I also have the Blueair 211+ and 211 Auto in other rooms and really like them, too. If I need air purifiers in the future, I will always buy Blueair.

r/AirPurifiersAir purifier for 300 sq. foot room, that can purposely make some noise?
9 months ago

I have the Blueair 211 and Classic 605. Both are great air purifiers and make great noise on high, but they appear to be older models, so may not be easy to find. If you end up buying an air purifier that is too quiet, consider also getting LectroFan Classic White Noise Machine. It has lots of fan sound choices and is the only sound machine I have ever used that is loud enough for me.

r/AirPurifiersBedroom Air Purifier with Wifi under $250

If you're looking at the Winix C610, you could also look at the T810 which has higher CADR and right now is going for cheaper ($185 on Amazon). Very similar looking models. Technically it would be "overpowered" but that just means it'll perform better at lower air speeds, which means you could operate it quieter than others. I know a lot of people really like the Blueair 211 and it's very popular. I'm personally not a big fan of the pre-filter and I found the fan noise of a different Blueair model to sound more high-pitched. Minor complaints and very much personal preference.

r/BuyItForLifeThe REAL best air purifier - I HATE DUST!
11 months ago

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.
