BLUEAIR Genuine Blue Pure 211+ Replacement Filter for 211+ Air Purifiers - AHAM Certified, HEPASilent Dual Filtration, Removes Particles & Odors, Genuine Carbon Filter

Expensive but worth it. Chicago was blanketed with thick smoke from Canadian wildfires for days. It was awful. Smell seeping in even when windows and doors were closed. Throat and eyes very irritated. This air purifier saved me 100%. I kept it on highest level. It removed all smell, microscopic ash. Love it.

I have always bought for this seller and I am confident of the quality. As soon as I replace my old filter the new filter makes the air quality in my apartment better.

We have two BlueAir purifiers in our house, and we have three pets. They are phenominal purifiers. We've purchased off-branded filters, as well as the official filters and hands down, the official filters are the way to go. Installation is extremely easy, and it reduces particulates in the air. Highly recommend every 6 months, or when the light on your purifier turns orange/red.

TL;DR — just smash the “buy button” and thank me later, OK? I bought this for the fire season in California, since after the last bad year, one couldn’t get filter replacements, let alone a new device. I also have a pet cat that sheds like she drinks water, and despite a Litter Robot, which is magic, it sometimes doesn’t turn, because of the weight setup. My friend had one of these BlueAir 211+ devices, and I could tell it worked well in their space. Sure enough, not long after buying it, the Canadian wildfires sent a ton of smoke our way. While those weren’t nearly as bad as when the fires were local, the city still looked like a stand-in for Bladerunner 2029, as before, it was still bad. The air quality was still sending people to hospitals. I have a dual-hose a/c unit that had run through the night when the air was clear, and then the next morning it was opaque and orange. Previously, the slightest amount of smoke would have woken me up. However, I had mistakenly left the filter on at high (usually not necessary at all), and with the older filter running in a corner, I didn’t smell anything. I had no coughing, no sneezing, no red and puffy eyes, no blocked sinuses…that can happen just from where someone HAS smoked in a room. It could have been days since someone smoked a cig, or worse, the WORLD ON FIRE outside, and my allergies go into overdrive. I swear by this device. I will never NOT be with one, or equivalent, ever again. I know it’s costly, but especially if you live in a city, buy this now. The air inside an house or anpartment, even when the air outside is (somewhat) clean, is still FULL of VOCs, your neighbor’s home/yard odors, cooking, pets, cars that still use gasoline, etc. When the Canadian wildfires blew into town, I smelled nothing and had no reactions, not even when I lowered the filter to low or medium. This thing DOES THE JOB! If you have bad allergies, you live in a city, you have pets, you cook a lot of pungent foods, you smoke inside (ick), your cleaning chemicals are toxic and pungent, we could go on… I have yet to encounter a situation where this device and the replacement HEPA and carbon filters (I get the extra chunky ones, and I place the cloth filter on the outside so these last longer), have NOT been able to conquer it before it’s ever a problem, or with just a few minutes circulating on high. As someone whose allergies break out over even the smallest of things, this is one of the best investments in my overall health, ever. It’s so efficient it catches many things that can also cause illness. I was also in another country recently, and they didn’t have these specifically, but I bought a pair of the same brand, just smaller — same level of quality. Until they arrived, I was sneezing every 5 seconds, and couldn’t sleep because my sinuses were all blocked. Once I had them, I turned those puppies on to full blast, and after 20 minutes or so…like nothing was ever there. I would also add that a lot of other devices don’t catch as much dust, fur, and whatever it is that ends up on the cloth outer liner, before ever going through the HEPA and then the charcoal. It’s because most only have a square, one-face HEPA, and not enough sq footage, even if they’re round or square. As a result, many of those cheaper ones eject a lot of dust that just falls over everything like a fine mist. I’m not saying you will NEVER dust again with this, but I dust half as much, if not less, than usual. If you have not guessed, I give this 5+ stars. Save up if you must, but if you have breathing problems, allergies, or just have odors you cannot control entering your space — this baby is all you need for up to 500 sq. ft-ish. Buy the larger ones, or more ideally, buy these and split them throughout your space. I find with these, that I use the fans and air consider less, because they push cold air UP, and it’s good, clean circulation. The smaller ones are awesome for basements, garages, closets, etc. I know times may be tough, and the cheaper alternatives may seem like a deal, but most of them don’t offer true HEPA, and usually the charcoal they send is paper thin (literally). The chunky charcoal one for this is as thick as my index finger, at least, so odors and other particulates really don’t get through all three phases (reusable and washable cloth outer liner, HEPA, then charcoal. If you want to go hog wild, you could always cut or tape on another charcoal layer for the fan’s exhaust on top. As I said from the start, buy this, you never know when it’ll come in handy for bad weather, for allergies, odors, and just your general health. You’ll notice the difference. Thank me later!

The reason I bought the Pure 211+ model is because the outer pre-filter sleeve fits over a metal housing. The air filter itself sits inside the same housing. Removing the pre-filter to wash it does not disturb the main air filter because of the metal housing between, thus not disturbing dust accumulated on the filter. Removing the filter itself for changing does not require disturbing the pre-filter. AFAIK, this is the *only* model designed this way and this is why we bought it. The pre-filter is easy to vacuum every 10-14 days to remove outer dust. The light on the outside of the housing changes colors when it is time to change the filter. The unit is in our bedroom and this light is not bright enough to bother us at night. We run the unit on medium speed and the noise isn't bothersome to us. Our previous room air filter was an Austin Air and the noise level is the same, so we are accustomed to it. Think: white noise. After owning and using it for six months, we are very pleased with the Blue Air Pure 211+ room air filter and highly recommend it.

We’ve had this unit for almost 8 months now. It works great and our bedroom is always odor free, less dusty, and we’re sleeping better due to less allergens. I was concerned about the filter change as I’d heard about some customers dealing with new filter odors. Zero issues for us! Didn’t notice a thing. Still the same comfortable system we’d grown accustomed to enjoying. We’ve satisfied. Only disappointment is the price. It’s a little too pricey - more than it needs to be. The producers are definitely making bank.

The filter fits perfectly in the humidifier. Now I just need to rememberer o change it more often. I think the price is a bit expensive for a filter

Perfect. On auto replacement every 6 months, and they have never missed ! Very dependable. Wonderful product.

I buy these replacement filters as needed throughout the three years I have owned the Blue Air 211+. It is very easy to switch out and replace the original filter. The filter works as expected, just like the original filter that came with the unit.

Good product. Easy to install

I'm a big fan of Blue Air filters and Air Cleaners , the quality of air cleaning and design is awesome. I have an asthma and especially in the summer need good quality air cleaning. I prefer to use the brand name I've found them to be superior quality . With the increase in forest fires during the summer months air cleaners have been a saving grace and Blue Air in my opinion after researching and trying several brands make some of the best!

Very easy to install and replace previous filter. Large area and thus very functional. We have been very pleased with the unit overall. Only downside is the cost.

I love it. I have it right beside client's heads on my massage table (through covid) and although high speed is a little too noisy, medium is just great and I put it on high when they leave to air the room. A nice purring sound; easy to meditate or sleep through. Highly recommended. I think I might have paid a little too much as I have seen them for cheaper since, but that's life. Replacement filter hasn't been needed yet, and I do love that I can wash the most external layer of particle net. This has been an excellent purchase.
