   A great product for the price .. I leave ours on during the day at the low setting. As Im a bit sensitive to noise I usually turn it off when we go to bed. The cloth cover easily comes off for washing and does a pretty good job at pre filtering the dust.

   Purifica el aire PERO SE QUEDA con el olor anterior.
   1. Lo usé en la cocina porque hice pescado y ahora le quedó el olor a pescado ='(
   2. Después lo usé para purificar humo de cigarro en la recámara y….. ahora al prenderlo huele a pescado + cigarro.
   Horrible…..

   Purchased back in October 2024 because I had moved into a basement room and with used furniture with visible water damage at the bottom, this is also near a busy road which brings in a lot of dust. I have outdoor and indoor allergies and for this first month living in the new place I tried to carry on hoping the dust and possible mold allergies won’t affect me but boy I was wrong. Since I was not in a position to buy new furniture at that time and needed a place I opted for the best next thing. After waking up for weeks with serious allergic symptoms that prevented me from having a restful night looked up many different air filters that would also filter mold particles and this one was the best in the market. From day one my sleep instantly improved and my allergy symptoms which are now none existent. A few things that I never thought I would come to appreciate from it was how effective it is at improving air quality with the smell of food after cooking, or keeping the air cleaner when ever I do my straighten my hair which is a lot. My air filter has been on 24/7 since day one and only now 6 months later I am seeing how much dust and debris each filter collects.

   Short version. Superb filtering, vertical discharge, high air flow, low noise, low power consumption, solid app, not cat friendly, MUCH bigger in person. Awkward to move as there are no handles or indentations to grip it with. There is a small ionizer that can’t be turned off (only 5 parts per billion, practically zero). The carbon part of the filter is worthless and adds an odd odor. It faintly smells like an old campfire pit that has gotten wet. To summarize: This is a big help with filtering out air born particles in the PM1 range when used in smaller spaces and when run on higher speeds. Long version. Exterior fabric pre filter stretches over a non HEPA filter. There is a weak ionizer to supplement the main filter so that it filters at HEPA levels without all of the back pressure issues associated with the tighter weaves of a true HEPA filter. With this design they are able to have really high CADR’s with low power consumption and moderate to very low noise levels. Nice compromise. I like it. The ionizer emits a maximum of 5 PPB of ozone which is 25 times under the FDA limit for indoor medical devices. The ionizer cannot be turned off. I see no dirt sticking to the walls so it might be a bipolar device. Either way it works well. There is also a thinly coated woven carbon fiber mesh that is supposed to help with odors and VOC’s but it does nothing at all. My VOC meter did not budge in the slightest. The activated carbon filter also adds an odor that faintly smells like the ashes in a wet camp fire. Again, it’s very faint. It did fade some over the first month but not completely. BlueAir sent me another filter cartridge and it had the same problem. My 311i+MAX had the same off gassing odor for a few days but then it dissipated. Others have commented about the 211 odor issue on blueairoutlet.com, so maybe it’s a hit or miss problem or maybe I just don’t like wet campfires. The carbon inner filter can be peeled off of the inside of the main filter. It wasn’t hard. I’m not sure if it’s a structural part of the main filter. I didn’t get a chance to try it out before I sent it back. I really wanted to keep the 211 around as my main work horse to protect the HEPA and carbon filters on my more expensive air purifiers. I bought this for my ragweed allergies and for severe allergies to household dust. For that purpose it’s done a super job and my particle meter stays near zero. My head and lungs breathe easier and there is less dust in general. The main filter has a tremendous amount of surface area. I took it apart and stretched it out and it is 64 feet long and 9 1/2″s wide. Pretty impressive. To get complete relief I had to run it much harder than I imagined. In my 150 sq. ft. bedroom with 11′ ceilings I leave it set on the 3rd highest speed 24 hours a day. I relocate it one day a week and will run it on high all that day along with a high speed floor fan assisting it to help get all of the allergens airborne until they are captured by the 211’s filter. I also follow all of my allergist suggestions as far as bedroom hygiene (which is a lot of extra work). All of this together gives me compete relief and I can breathe and I save a ton of money on Tier 4 drugs. (Household dust triggers my COPD). Some comments on airflow and correct sizing. I started with the BlueAir 311i+MAX and needed to run that at it’s highest speed to keep the dust under control and to offset the effects of a dirty HVAC system. (My system can deliver dirty air at a rate faster than the purifier can clean it). Running the 311 wide open was an annoying amount of noise so I moved up to the 211i+MAX and ran it on 3. Lower speeds did not benefit me very much. Sleep mode and low did absolutely nothing for my breathing. Keeping the purifier clean has been far more work than I imagined. The exterior pre filter (sock) is a very loose weave when stretched out over the machine and it lets quite a bit of dust get through to the main filter. I vacuum the exterior pre filter sock every 4 to 7 days and will vacuum the main filter at the same time. My vacuum cleaner has pretty high airflow and I was collecting about a quarter cup of poofy to a very fine dust every cleaning session. N95 mask recommended. This has been a wonderful machine and I love it but I hated the smell so I sent it back on the last day. It took 7 more days for the odor to fade away. I’m not sure if it’s just me or if any average person would react to that smell like I did. BlueAir needs to do better. The thin plastic mesh that they lightly dusted with activated carbon and then glued to the inside of the main filter is worthless and needs to go. To advertise it as effective with VOC’s and odors is dishonest. A high integrity company would not do that. This is a classy and high functioning particle air purifier that can clean A LOT of air cheaply but it’s hampered by a cheesy and cheap activated carbon dust insert. Power consumption was outstanding. On the lowest speed it burned 6.25 watts. Second speed 10 watts. Third speed 18 watts (amazing airflow). Highest speed 41 watts. Power consumption remained steady as I simulated a clogged filter. The LED’s and displays can be dimmed with the control panel or the app. The app really began to grow on me over time. It gives you compete control of the machine and the ability to make incremental blower speed adjustments. The app is 2.4GHz only. Very nice air purifier. The fit and finish is good and it looks good. It also performs well. My lungs found its presence in my bedroom to be comforting and healing.

   I love this air purifier. We live 2 blocks from where the Eaton Fire stopped and we had this ordered ASAP. We also got the larger one too. The house does not smell like smoke at all and it was very easy to set up. We also have 2 cats and we are a family of 4, so the house is always one step away from stink town. You know how if you have cats and you go away for a few days and come in and the house smells stale and ick (even with a cat sitter scooping everyday), well I just got back from a trip and did not walk into a house that smelled ICK! Plus it is beautiful and easy to clean.

   Work very well, purchased 2 more for other areas. Dust has been cut down, and noticibly difference in any lingering smells. We would use scented mop liquid, and before you could smell it 2 days later, and our dogs would get sick from the smell. After running these, 2 hours later no smell.

   Didn’t try it. Just opened the box and saw the gigantic machine and returned it. It’s way too huge. I bought it to save some counter/floor space, which defects the purpose. Keeping the old BlueAir air purifier which I love. Comparing the regular, old BlueAir air purifier with this machine in the attached photos.

    Very easy to use and made a difference for allergies and wildfire smoke in our area. I leave it set on auto and it kicks into high gear whenever there’s anything in the air – cooking smoke/odors, hair spray etc. Noise level is barely noticeable, only time we I hear it is when it it’s running on high and even then it’s pretty quiet. Husband suffers from allergies and he wakes up able to breathe clearly now so that makes it worth it to me.
