I live in an older building and have been concerned about the air quality for a while now. I used to own another hepa air purifier but remember how loud it was even on the lowest setting, so I decided to give this brand a try. I put it on night mode and can’t hear anything. The only time I can hear it is if I put it on the max setting. My breathing has improved greatly, no more coughing at night and there is way less dust in my apartment. The air definitely smells better too. I am thinking about buying another one for my moms room as well. Would definitely recommend as it works great is quite and looks stylish too!

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 😐…

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!

This air purifier is quiet and efficient. It runs throughout the day mostly silent, cleans our air well, and has a beautiful design.
I am impressed by how quiet this air purifier is! I’ve had many air purifiers over the years and most of them were loud, either with fans or electrical humming. The blueair purifier runs all day completely silent. This is one of the top reasons I wanted it. The only time it becomes louder is if it detects more pollutants in the air, which kicks the fan up higher. Even at it’s highest setting it’s not loud. I would say it’s less quiet than a box fan. I LOVE how quiet it is.
I have sensitive lungs and I suffer when the air isn’t clean. The pollen in the air has been brutal, so I wanted an air purifier that could work in addition to the other ones in our home. We have a little town home and I use this one in our living room. I have placed it at the corner of the living room by the dining room and kitchen. I accidentally burnt a meal while cooking and the air purifier automatically kicked up to the highest level until the air was clean. That alone is impressive.
Recently, all of our windows were open and the air purifier fan kicked up to it’s medium level fan, then it’s high level. My kids and I were wondering if the fan had malfunctioned, none of us had done anything to cause it to react. I went to the window and realized that it was hazy and smoky outside. We immediately shut all of the windows. The air purifier stayed on until the air in our house was clean again. Then it went back into low-level, silent mode. I absolutely LOVE the auto-detect feature.
It’s small enough to be out of the way, but big enough to do it’s job. I love the beautiful design. It’s about the height of a box fan. I love that it’s round and tall. We have the original prefilter that it came with but I’d like to purchase more. I’m excited to try out another color, but I also really love the grey.
The only downside is the prefilter. As much as I love it, our cat loves it more. She loves to launch herself full speed across the room and do a running leap at the air filer, grab at it with her claws and fling herself around it like it’s a toy just for her. She ferociously rips and pulls at it like it’s a beautiful scratching post. We’ve tried putting new scratching pads and all around it to deter her, but she loves the blueair more.
I have removed the prefilter in hopes of detering her, so that she’ll leave it alone. She has lost all interest in it with the prefilter removed. I’m bummed because I love the look of it WITH the filter on.
It is so hard to take the filter off and put it back on. I kind of wish it was able to simply velcro on instead of having to slide it on. It reminds me of trying on prepregnancy pants after I had my kids. So difficult to shimmy into!
Despite this one problem, I love this air purifier and will definitely be purchasing another in the future for our downstairs bedroom!

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.

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 own 3 of the 411+ that are used in bedroom/office for last few years and I’ve have been very pleased with the 411+ air quality performance so when I saw a deal on the 311+ Auto for $195 I snatched it up instantly. Its a lot bigger then the 411+ but the fan sound is just as quiet if not quieter then the original 411+. It’s just the right size for the living room/kitchen. We always leave all of them running on second speed and you honestly don’t hear them at all but the air quality is much fresher and cleaner. Cooking smells are gone within an hour and lot less dust during the winter months when the furnace is running and no allergies in the summer months. Would recommend any of the blue-air filters when they go on sale from time to time or even buy an warehouse deal open box one on Amazon as most of the time it’s just a return that someone changed their mind. The only con is the original filters can get a little expensive but you can buy third party for a lot less if you choose too but I did notice a difference in the air quality from the original filters vs third party so just a heads up if choosing third party filters for any blue-air air filters.
