About Blueair

Blueair air purifiers have HEPASilent technology delivering maximum filtration with minimum noise. This pioneering Blueair filtration technology cleans the air faster and produces more clean air by combining traditional mechanical filtration with electrostatic charging of particles. Over two decades ago, our Swedish founder wanted to ensure his children could breathe the same clean, fresh Swedish air inside their home as they did out in the pristine Swedish countryside.

Product Description

"Blue Pure 311 air purifier quickly cleans 340sqft medium room in about 12.5 min or up to 1,632sqft extra-large space in 60min, on high. Only Blueair air purifiers use HEPASilent™ technology, delivering maximum filtration with minimum noise. Combining mechanical filtration with electrostatic charging of particles produces clean air, faster, and much more quietly than traditional HEPA filtration alone. Delivers high performance with simple one-button control in a lightweight, compact package and includes a washable, pre-filter in Arctic Trail (Gray). It can also be customized in other Swedish-inspired pre-filter colors that are sold separately. Carbon filter traps light household odors from smoking, pets, cooking, and more. Award-winning, sleek, Swedish design compliments your aesthetic while working hard to clean your air so you can place where it will be most effective at capturing airborne particles & odors without worrying about it cramping your style. Independently evaluated for safety standards and third-party tested for performance as part of the AHAM Verifide® Program for air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 220 for fine smoke particles, 210 for pollen particles, and 210 for dust particles.

CLEAN AIR IN A MATTER OF MINUTES: Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration. When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration. According to AHAM, air changes per hour (ACH) is the measure of the outside air volume added to a space divided by the volume of that space over a set amount of time.

REMOVES ODOR & PARTICLES: Blueair models with HEPASilent's mechanical and electrostatic filtration produced higher CADR, lower noise, and had lower energy consumption vs. the same models with only mechanical filtration (H13 filter). Tested on PM2.5 (0.1 - 2.5 μm) up to 90min; Tested on Influenza A (H1N1) with a minimum reduction rate of 99.99% in 60min.

BACTERIA, VIRUS & MOLD SPORE REMOVAL: Tested to reduce E.coli and Influenza A (H1N1) with minimum reduction rate of 99.9% in 60min; Tested on A.niger with minimum reduction rate of 99.9% in 60min."

AI-generated from the text of customer reviews

310 customers mention228 positive82 negative

Customers like the noise level of the air purifier. They say it is quiet, blends in like a nice white noise, and is almost like a sound machine. The night feature is completely silent.

"...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..." Read more

"...It is extremely quiet during normal operation...." Read more

263 customers mention245 positive18 negative

Customers are satisfied with the quality of the air purifier. They mention that it effectively cleans the air, removes dust from the air fairly well, and clears the entire floor. It is small and quiet, and does a great job filtering out the pollen. It's unbelievably good at monitoring air quality and the slightest pollutant. It keeps their 3 bedroom apartment smelling clean, even though they have 2 teenage boys and a dog.

Customers like the appearance of the air purifier. They say it blends with any decor, and is a nice addition to their home. They also like the new covers, which have a more pleasant color and texture.

Overall, customers are satisfied with the appearance and quality of the product.

367 customers mention221 positive146 negative

Customers are mixed about the performance of the air purifier. Some mention that it seems to do the job well, and quietly, while others say that it completely quit after a few days.

This purifier is amazing! Allergies, be gone!
5 Stars
This purifier is amazing! Allergies, be gone!
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!

5.0 out of 5 stars Sleek and quiet
Reviewed in Canada on March 7, 2023
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.
