   I bought it last year when the walls in my apartment building were painted with some stinky paint, and I started feeling nauseous and had a headache because of that toxic smell. This purifier helps to deal with such things and it does it quickly. It cleans up the air when I cook, it saves from the city smog and the consequences of forest fires. This one is not big, but it sucks the air in from all sides, so it’s way more effective than rectangular filters, even if they cost more (I have something to compare it with). The filter is easy to clean, it’s not noisy, and the light shows it’s sensitivity as it reacts to the changes in the air very fast (if I use a hair spray, it goes red almost immediately, even if I’m 5 meters away from it).

   I live in Texas where we have tremendous grass and tree pollen. In some years I have come down with debilitating sinus infections. My daughter did research and said this would be a great product. It is. I have not had any problems since using this. It is fairly quiet and does not take up much space.

   Tengo 2 purificadores, un dyson y este, el primero tiene control remoto y una pantallita que muestra el funcionamiento tiempo real y coincide con “lo qué pasa” en el consultorio; me recomendaron mucho este otro y en su modalidad automática hace lo que quiere, estas quemando algo y el humo pasa literal frente al aparato y no se enciende 😐…

   Works great and very quiet after over 2 years. Placed it in our kitchen and have only replaced the filter once.

   En Monterrey donde radico estamos teniendo problemas con el aire y aunque llevo 3 años con el producto y funciona bien he investigado la marca y dan información confusa sobre el producto. Tiene un filtro HEPAsilent que no es un filtro HEPA real. La marca engaña con esa información porque hacen creer que si es HEPA real. Solo por eso estoy decepcionado de la marca!

   This is now our 2nd Blue air purifier. I originally bought the smaller Blue 411+ for our bedroom and I was very impressed with how having that in our bedroom improved my lifelong allergies that I take a daily pill for. Prior to getting the smaller 411+ I would very often wake up with a stuffed nose. Yes, we do have 2 dogs but they are not allowed in the bedroom due to my allergies. I honestly didn’t have high hopes for the smaller unit but after a couple days of it purifying the bedroom air, I noticed a huge difference. I began waking up with clear sinuses and the room smelled “different”. Not a bad smell but maybe just NO smell? Anyhow, after giving the little Blue a good 30 days to prove itself, I knew I needed a larger one for our living room. This is also where our dogs (golden retriever and black lab) spend most of their time with us when they are inside. And having these 2 dogs and allergies doesn’t make life super easy as cleaning goes. I have to vacuum daily or every other day (minimum) and will at times pull up what looks like a small dog inside my vacuum canister. Especially, when my golden is blowing her coat. Finally after comparing, I went ahead and ordered the Blue 311 Auto for our living room which is approximately 420sf. I also bought a separate filter cover that’s shown in my pictures and an additional filter to have on hand. The unit arrived well packaged and without damage. It came with a main filter installed and a a light gray filter cover but tbh, I will use the light gray cover while cleaning and drying the dark gray cover I have on it now. I as I prefer the dark (name is actually Winter Reed) over the lighter gray. I also like the quality of the upgraded cover. It’s a bit thicker and looks nice. The set up was simple. It’s really just plug it in and go. I like that this unit has 4 mode settings and indicator lights to show air quality and when the filter needs replaced. I have noticed one time when out of nowhere the air quality sensor light briefly turned from blue to orange then back to blue. The light sensor color indicators and level info are Blue (good), Orange (moderate), and Red (polluted). The main filter change sensor is supposed to switch on after 6 months of use but I haven’t had it long enough to confirm if that works yet. For maintenance, I do run my vacuum brush over the outer filter cover once a week to clean any dust off of it which, there always is. This was also an immediate indicator to me that this fella is doing its job! I will also run a damp cloth on the the plastic exterior at the same time just to keep it clean and in the best working condition. Noise Level: This 311 Auto unit has 4 modes. ✔Auto Mode: (fan speed will change depending on the air quality it senses). ✔Night Mode: (whisper quiet, low speed) ✔Everyday Mode: (medium speed) ✔Boost Mode: (fastest speed and very loud). Boost mode is like, wind tunnel loud! Way too loud for us to watch TV in the same room if it was on. But this mode is not for everyday use. The only time I’ve used boost mode is when there is a specific reason i.e.,dogs came in from rain or I may have cooked/baked something that has a lingering smell, etc. I would just turn it on boost for 10 minutes or so to dissipate whatever the odor issue may be. We typically have it set on auto mode or everyday mode and it’s very, very quiet. I would say auto mode is more quiet or no louder than an average fan that’s on it’s lowest speed and everyday mode is maybe as loud as a fan on medium setting. ▪️Please see video I took of the different modes to show the sound difference between all four settings▪️ I have now had this particular unit running 24/7 for about 2 months and we love it! We live in Washington State so when it rains and our fur babies go out for break, any “wet dog” smell is gone in minutes if I kick in the boost mode but everyday mode will also take care of that within an hour or so. Sadly, I also know fire season will soon be upon us for summer and I have no doubt both units will do a fantastic job at keeping the quality of air inside our home filtered, clean and smelling fresh during the seasonal bad air quality. We will be tackling a full home remodel next year which we’ll be adding central heating and air but even then, I plan on keeping both these units up and running! Would I recommend this Blueair 311 Auto? Absolutely 100%. Summary: All in all, if you suffer from allergies/asthma like me, have animals, or simply a home without filtered air and are teetering on whether or not to purchase, go for it! You won’t regret it! Personally, these air purifiers have honestly changed my life! I wish I would’ve found this company sooner! I HIGHLY recommend! If I must find something negative, I guess I would have to say their OEM filter replacements are pricey but this was not a deterrent for me. They also offer an auto ship filter service for a discount. I give this an easy 5 star! (I was NOT paid for this review and was not asked to leave one. I have no affiliation with this company other than being a new-ish forever customer)! Hopefully this will help someone!

   We have a lot of construction going on around our home due to it being a new community, so there was a ton of dust in our home. We got this purifier about 2 years ago and it drastically changed the amount of dust we had. I was wiping down our countertops continuously, multiple times a day. Now, I wipe them down maybe once a day and they have little to no dust! I have another brand purifier for our bedroom and it’s disappointing, dust every day. I wish I had purchased this one for our upstairs as well as our downstairs. This has been a fantastic purchase! It’s very easy to use, you can easy clean external filter and the internal can be changed easily. It’s a decent size so we had to find a place where it wasn’t super obvious, but it also needs to circulate air, however, the white and gray blends in so it isn’t an eyesore either. And, it’s seriously worth it to have clean air and clean countertops!

   This is the second BlueAir air purifier I’ve purchased, and I absolutely love them. I use this one in my living/dining room, and I have it normally set on auto. It is whisper quiet when the air is clean, and still fairly quiet on the next level, only getting loud but still not unbearable on the highest setting when it is cleaning the air. I have a small kitchen so anytime we cook anything the smell inevitably fills the dining and living room. This air purifier then immediately kicks into high gear and within an hour cleans the air. Very efficient in that regard. It also does an excellent job of reducing dust, as much less dust accumulates on my furniture now. While I can say for a fact if that will help with allergy relief since fortunately I don’t suffer from it, I assume less dust helps. While the air purifier is very light weight, it still feels very durable. It also looks great anywhere in the room, seamlessly blending into surrounding furniture unlike other air purifiers, and isn’t too big or too small so can really fit anywhere. I’ll definitely be purchasing more purifiers from this company for other rooms.

    This air purifier improved air quality discernably in our 2-bedroom condo during the recent choking wildfire smoke. Glad we bought it. Very quiet in night mode and acceptable during higher settings. The HEPA filters can be replaced easily however they are still okay after about 100 hours of use in the medium speed setting and with closed windows. The touch controls are neatly integrated and unobtrusive however we would prefer simpler ergonomic buttons or nobs located on the side because it is not easy to find the right setting without numerals or idiot dots. Please redesign the controls to earn 5 stars.
