Blueair - Pure 211+

the main thing is to avoid the flashy stuff ionizers, HEPA-type filters, or models that don’t share their CADR ratings are usually more marketing than substance. what actually matters is solid airflow, real HEPA filtration, and something that can quietly run all day without fuss. washable prefilters are a huge win if you’ve got pets that shed. that’s why i like stuff \[like this\](https://best.hochzeits-shopping.com/jGNa) cause it just works without overcomplicating things. nothing fancy, just fresh air and less fur floating around.

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.

I bought the BlueAir 211+ (I think it is, large rectangular thing) because of its energy efficiency and how quiet it is. The pre-filter is easily removed and washed, and it's remained silent at night after a couple of years. Also, it wasn't expensive and it looks somewhat inoffensive. I would far prefer the IKEA style hang-on-the-wall or side table type that wouldn't take up as much space, but I haven't read any actual reviews suggesting they're good.

Air purifiers don't do a whole lot for asthma (^(*the studies I saw were from a couple of years ago, so if new evidence is out, please link it so I can update my knowledge*)), but a good air filter will attract dust mites and cat hair and other stuff. Check your allergy tests to see what it is you're allergic to, and ensure your air filter will capture it. The biggest key to one of these working is air flow. If you run it on 'low', it won't work well at all. If you have gaps/air leaks around windows and doors, it won't work well. If you own your own house, you can install a filtration system tied to your HVAC - that way you can often get good airflow without all the noise of a fan in your bedroom. If not, you're bound by the room air filters. Anyway, I settled on a BlueAir 211+ because of energy efficiency, and while it's annoying to be in the same room when it's at full speed, it's not as bad as some other units. The Winix C545 (I think they were) were noisier and used more electricity.

We like Blue Air. Highly rated and reasonably priced. The filters aren't cheap, but there are non-oem available on Amazon for a reasonable price. They last about a year. We have had the big 121 model for at least 7 or 8 years and it is still going strong. Also have a 211+ for about 4 years and a 211 for 5 years. No problems with any of them. Bought daughter Medify. She likes it and uses it constantly because she lives in center city Philly. She has had it a few years with no problems. Lots of good choices.

I had bought one of these for my mom. They work ok. I’ve used several other brands including Dyson, blue air, and iRobot’s aeris. Blue 211 by blue air is the best one I’ve used. Don’t buy from them directly as they have terrible customer service. That’s the risk with them. Aeris units are difficult to get filters for but have comparable performance to the blue units. Dyson air purifiers are terrible with dust and fur. They are the best for smells.

Stoner here, get a bong or pipe, something that doesnt stay lit as long and always use a smoke buddy. Can get a inline fan + carbon filter and a furnace filter taped to a boxfan. Or get something like a blue air 211 thats a combo hepa+carbon. Or even more optional, find a window and get a window fan to direct exhaust outside and sit right in front to smoke.

duct tape a 20x20 furnace filter to a box fan. Won't find a cheaper effective air purifier. i used 1000merv for it. I have a blueair 211+ which i paid 400$ for and the filters are about 80$ each (changed once every 6 months) and the furnace filter boxfan combo is almost as effective. Really almost the same thing as the blueair minus the carbon filter. I have asthma from a auto-immune condition, and even grease from cooking messes me up, but i just keep the boxfan combo in the kitchen area and is a massive difference. Can also get the furnace filters for dirt cheap any time other then winter. (since thats when most people boot their furnace up and actually need the filters, so the price goes up because of demand.) I paid 50 for a hurricane brand boxfan brand new because that was what was recommended and 20$ for a 4x pack of merv 1000 furnace filters. honestly can prob use any fan though and likely can get them dirt cheap at a local 2nd hand store for like 15$ and been plenty. I actually have been considering selling my blueair and just getting a bunch of box fans/furnace filters. Fans are cheap and the filters are cheap, for the price of my blueair i could of had 10 box fan combos going in every room and still had cash to spare AND better quality air. TBF though, they do look like shit in comparison to a actual solution. I will also add that IMO, levoits products are useless. had some really bad experiences with their products breaking fast and not really providing much help in air quality

When i did it, i really didn't think it would work as well as it does. I still prefer my 4-500$ blueair 211+ because it has a fabric filter and carbon combo, but at the same time, the price of the filters is as much as another small purifier lmao. i will say though, its not pretty at all, but I breath ALOT better with 1 purfier in my kitchen and one in my room. the boxfan one stays in the kitchen because the filters are cheap lol

Personally i have asthma and have 2-3 levoits in a short period which i found didnt work well, and then 2 broke within warrenty period, and just switched to something better. Even when it running as intended, i just found their filters didnt do much of anything to help, IMO owned [LV-PUR131S](https://www.amazon.ca/gp/product/B07NR9KL8J/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) and it broke within a month, rmaed, broke within year warrenty again, refunded and got a blueair 211+, actually improved my symptoms unlike the levoit, also just use boxfan+furnace filter and imo is way more effective then levoits purifier for less then a 1/4 the cost [https://www.reddit.com/r/AirPurifiers/comments/1hi2izu/comment/m2vrhtz/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button](https://www.reddit.com/r/AirPurifiers/comments/1hi2izu/comment/m2vrhtz/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)

Don't get a winix 5500-2. I got 2 of them a few years ago and within months of each other the bearings on both started making a horrible noise. I looked into fixing it myself and it turns out it's very common, and it's nearly impossible to fix because it's a sealed system. They cheaped out on a 10 cent bearing and now they're pretty much useless. My blueair 211+ has been great though. I don't really know how they would be a scam. Just like any filter, they take stuff out of the air.

Ah, that's too bad. We've got a bunch of 411s and they're all still going strong. They're fairly simple, which is I suspect also why they're relatively reliable. I wonder if it's repairable honestly. Like maybe something just came loose inside there. I actually couldn't remember exactly when I bought all of ours so I looked it up in my Amazon history. We have three 411s that are all 8 years old now and still going. We have two 211+ models and they're 7 years old. And then 3 411 Autos that are now 3 years old. So far no problems with any of them running all day every day.

Seconded - I love my coway airmega 200ms and I also have the blueair 211+ which is a bit bigger and both are awesome.

I have a Blueair 211+ for my living room and its awesome and a coway airmega for my bedroom, both are solid choices and highly rated. I do not buy name brand air filters (just amazon knockoffs) that work great.

Of those 4, the BlueAir 211+ is a powerhouse. The Numinoviwhatever is a generic brand that I'd avoid. The white Honeywell is severely undersized for the room. The black one is likely undersized as well. Remember that even the biggest and best purifiers (the BlueAir 211+ cleans more air than anything but a Coway 400 or a Smart Air Blast) really only effectively clean 300-400 square feet on their own, so you will likely need multiple units.

I don't like the fabric design either. I just got a 211, because I need to clean a bigger room and it was the only good deal on craigslist. I can't imagine it being graceful to remove without making a dust cloud. I've also seen some comments that cats can interpret it as a scratching post... I've always had brand loyalty to coway (they lowered the cost of home air purifiers, right when I needed it); the cover keeps the dust contained, and their stack set-up of a prefilter, charcoal, then hepa makes clean-up much easier. I don't think I even need to take it outside. Winix has the same setup. I have one newer coway 150; these are more modern, and I don't like the sliding prefilter -- if you make the mistake of not letting it coast down and it's dirty, the air blows the dust around. Yuck.

If you’re smoking flower in doors, nothings gunna help, really. Vape it and it goes away much faster. I have a blue air filter(one of their big ones meant for like 1200sqft), in my room, I crack the window and blow a fan through it to pull the vapor out. Smells gone in about 30 minutes. Have to keep the door shut tho.

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.
