Customer Ratings & Reviews

Unit extremely quiet, compact and unnoticeable, and shows noticeable difference in moving air. Dust accumulation on furniture and desk showed improvement in a room size of 20x20 within 24 hours.

Extremely easy to set up, took just a few minutes. We could quickly feel a difference in the air quality in our house.

Fantastic air purifier. Found it on sale and it was price matched immediately. Roommate was making steaks once in the kitchen and the bedroom this was located in was incredibly clean smelling and I could actually breathe. Seeing it kick into high gear when the smell came into the room and it clearing it out promptly was great. Would get a second one.

It really gets the job done. Simple and easy to use. The filter was a no brainer to change. It scores high on many review sites.

Very easy to set up. Just need to push a button. I have been using the auto feature and there have been a few times (usually when cooking) when the purifier detects high particle levels and increases speed. The fan is so quiet it is hardly noticeable during normal operations.

This allergy season has been bad, especially for my wife. We have a Blueair 211+ but realized we probably needed to add more units to our home. We moved the 211+ to the living room and added the 311 to the main bedroom. We also added a 411 unit to the spare room. It's been a night and day difference on a few fronts. Firstly and most importantly, we're not suffering from allergies as bad and my wife's use of her inhaler has greatly gone down. Additionally, there is noticeably less dust around the house. The 211+ is louder and its light brighter (makes sense since it's a bigger unit), so having the 311 in the bedroom now has resulted in a darker and quieter room when we're sleeping. We mainly stuck with Blueair based on their reviews in Consumer Reports and have been happy all around.

I purchased this model after reviewing the comments for similar models on the Best Buy and other websites. I was looking for a unit that would remove the dust from our master bedroom. So far it seems to have made an improvement. It was delivered quickly and put into service immediately. I was impressed over how quiet it is. I normally run it on medium speed during the night time. I have it plugged into a smart plug that is controlled by Alexa, so it comes on before bedtime and switches off automatically in the morning. The unit remembers the last speed setting used, so it comes on at the same speed each time. I am pleased with my purchase and would buy it again.

I bought the big brother to this first, the 311+, after going they many air filters that didn’t seem to do much despite having cool features. These have an auto detect mode but I honestly leave them in the middle setting myself, and on high when I went to clear a space quick. The first air filter brand that truly gave me a crisp cool sweet smelling air! Breathing quality up and constant nose congestion at home gone! A Godsend. I had a levoit that sucked a lot of yuck out of the air, and don’t get me wrong worked well, but these I like more. I think the charcoal layer really gives the air a NOTICEABLE great clean smell and feel.

The auto mode works well. Clean the space really fast. We hear almost nothing when the air is clean. We also like the design. You can buy extra outside filter in a different color to fit your room.

Nice and compact air filter I like the indicator light to show how dirty your air is, also I like the night mode so that the light is not shining at night

Everyone should use an air purifier. Notice a huge difference when this is on in our house vs not on. Love having it in the kitchen too when we cook.

Bought these becaus its one of the top brands. Was able to price match it at the rime. Ive seen less particles in the air since its been around and we love in a farming area so its a blessing.

We love this air purifier! Not too clunky, attractive enough, great performance. I have two large dogs and three toddlers- there’s a lot going on in our house. When we started using this we noticed an almost immediate difference. My toddlers have contributed to the testing process by knocking it down on our hardwood floors multiple times. This thing has been a champ and we haven’t noticed a decrease in performance. Replacement filters are a bit pricey considering the price of the machine, however I’d still pay for them over something like Dyson.

I've been using this purifier for a few weeks now in my office at work, its about about a 200 sq/ft space. I also use a 411 auto in my bedroom at home, and have been happy with both my Blueair purifiers. Attractive and simple design that doesn't look out of place in the room or like a piece of medical equipment. I have been enjoying less allergy and sinus related issues since adding these to my most frequented areas. Filters dont seem too overpriced and last for 6months, probably more but thats when they tell you to replace it. Several different types of filtration from a charcoal filter for to electrostatic. Happy with my purchase would recommend to a friend.

Excellent air purifier that is easy to use and works well in small rooms. As a northern Californian, fire season has gone from being a couple of months long to now being about half the year. We invested in these air purifiers after watching a the CBC news test 5 popular brands to see how they stack up. Blue did the best at reducing the contaminants in the air. Let’s see how it fares when fire season starts in California.

This air purifier works better than I anticipated. There is a sensor on the machine to tell you how bad the air quality is in the room and will change as the air gets cleaned. I move it from room to room to clean the air. After some time in a room, the air is noticeably different. It even works great to get the odors out after cooking. It's a little big and cumbersome if you are trying to move it around but it is very lightweight. The auto and night settings are basically silent. The medium setting, you can hear a little but it's not distracting. The high setting can get a little noisy but I usually run that for a short time and bring it back to a low setting. All in all, I'm happy with the product. I am going to purchase another one for my parents' house.

This was a gift to the family. It’s dues exactly what it was made to do. No issues and easy to set up.

Works great and quieter then others. I’ll run it on the sensor and have had no issues.

Very quiet, effective and easy to use. Control panel on top is as simple as one tap for auto, two taps for low, three taps for medium, four taps for high. On auto and low we can barely hear it in our bedroom. On medium its non-intrusive white noise and I can still easily hear the TV or conversation. High is louder but also very effective at moving the air in even a fairly large bedroom or in a living room.

Works very well even on whisper setting for night time. Really helped a lot with my wife's seasonal allergies.
