Customer Ratings & Reviews

I recently purchased an air purifier from Best Buy, and I’m thrilled with its performance! The unit is sleek, quiet, and incredibly effective at improving air quality. Within days, I noticed less dust and fresher air in my home. It’s easy to use, with intuitive controls and a compact design that fits perfectly in my space. Highly recommend this product to anyone looking for a reliable air purifier!

This was a great purchase I have noticed the air seems much cleaner. I no longer wake in the morning with a stuffy nose. It is very quiet only time you notice it’s there is when it notices a decrease in air quality and is working to bring the level of air quality back up and even then the sound is nothing unbearable. I would definitely purchase this again and plan to.

I’m really happy with my purchase. This air purifier is exactly what I needed. It checked all my boxes. It looks very nice, fits my aesthetic perfectly. It has HEPA and carbon filter . It’s so quiet even on the highest level the sound is not too loud more like white noise . The filter is easy to replace the app let you know when the filter needs to be changed. The set up was very easy on my phone and connect to Wi-Fi very easily. I love that I can control it from anywhere. I’m also very happy that it tells me how long it will take to clean my air. It’s really improved the quality of the air in my home. my husband vapes and this helps keep my air fresh and clean . I definitely recommend it and am looking to purchase another one for my bedroom and one for my mom..

Received this item very quickly. Very easy setup. I programmed it to come on at 10:30 pm to clean our bedroom air right before going to bed. We have furry pets & I believe that I am somewhat allergic to their fur & dander, so I thought this would help my sleep. It does a great job & continuously monitors the air quality. Our bathroom is just off our bedroom & I've noticed that it is so sensitive that it even senses my wife's perfume that she uses after a shower and indicates a higher level of "pollution" .... an increase in airborne particles .... which quickly disappears after she's done. But I found this to be quite interesting! It is quiet & more than sufficient for this room size. One Note: DO NOT put anything on top of it. I momentarily laid my cellphone on it & the touch sensors somehow responded and messed it up, so I had to remove it and reprogram it, which causedvit to lose several days of monitoring data. No biggie, but it waa aggravating. Other thsn this, I am very, very satisfied eith it.

Great for our downstairs. Fan is always running on automatic and cant hear it at all unless the air quality isnt good. App is great. Easy to setup and filter lasts 1 year!

Great product! I've been using it for a couple of weeks now and there is a huge difference in the room's air quality. It's not a very well-ventilated room, and it has worked wonders. I wasn't expecting it to be so big, though; it’s about the size of a 16-inch laptop

This is working great! Love it! Nice and quiet!!

Works very well, and is very quiet, I will be buying more.

Good quality and price not noise at night. It has a night mode and is suitable for a small room.

We purchased 2 Blueair - Blue Pure 511i Max 926 sq ft HEPASilent Small Room Bedroom Air Purifier - White/Gray. They are working well. We purchased them to help with removing contaminants and odors from our townhome.

Air Purifier – "5 ⭐ Quiet, powerful, cheap filters. Best budget purifier

Works great. Have the larger one upstairs in the family room and this one in the basement for smaller area. Has auto fan speeds and changes color with air quality. Highly recommended.

Great price and works as described. I was struggling with allergies and congestion in my bedroom. After day 2 of using this in the house, my sleep has dramatically improved.

So far I’ve been liking it. It is very quiet and I have this one in the bedroom. I do recommend this

Works very well & I am very happy with the purchase. Would definitely recommend to friends & family.

This filter has been very good for my room , it removes dust and is very quiet.

I think it’s easy to work so far no issues. I thought the Wi-Fi was messed up but disconnects of corse when u unplug it. Plugged it back in & room a few secs but works. Dropped it once by accident too. Seems pretty durable

[Employee of bestbuy] Great quality and value as well as appearance of the product. Will recommend to others. Will purchase more.

I love it the stuffiness in my room has reduced so much

Once, while hiking atop an 800-year-old volcano in Iceland, with a stiff wind blowing from the north Atlantic, I breathed in more fresh air than I thought I might have ever needed for the rest of my life. That might be an overstatement, but conversely, when you are breathing air that’s less than ideal and need a helpful hand in picking the putrid particles from the pleasant, you can rely on the Blue Pure 511i Max to help sort out the sordid air you may be breathing. How does this Swedish design firm achieve this? Surprisingly, not by capturing and ladling breathy ABBA harmonies throughout the room. Nope, it’s more like the magic of HEPASilent™ filtering employed at customer-selected speeds via the simple on-unit buttons, or via the available app. In addition to the three manual speeds, there are automatic and night modes, where the night mode drops the fan speed to a quiet minimum sound and an appropriately dim lighting scheme. The automatic mode seeks to filter out particles in the air to a level of PM 2.5 (Particulate matter of 2.5 microns in size), and is measured by an on-board particle sensor. As the air is being cleaned, the particle sensor measures and reports the perceived air quality to the app which shows five differently-colored display illustrations keyed to the air quality. Keep in mind that this unit was designed for smaller, closed rooms that are less than 193 square feet, or about 14 feet by 14 feet. The app also keeps track of the unit’s efforts in cleaning the air as well as use and filter condition based on time used and air quality filtered. Overall, a useful and well-developed app. I have to admit that I house a degree of skepticism towards the efficiency of products in this market segment. I don’t quite understand how a relatively slow-moving fan barely moving air can be expected to clean all the air in a room. It’s rated at 4.8 air changes per hour, which must be in the fastest speed, but it’s hard to believe that the slower speeds would do very much, other than clean the air in a very small and local subset of the room. The proof of effectiveness is, of course, going to be lodged in the filter and prefilter over time. This Blueair model is designed to capture smaller particles that pertain to elements like smell, smoke, pollen, as well as regular dust particles. The filtering of particulates of PM 2.5 size mentioned in their literature, is achieved by the use of electrostatic, mechanical and/or carbon filtering. There are three different filters that work with this unit. The included one, is the Particle and Carbon, and optionally available are the Allergenblock and the Smokeblock, which are self-evident. Some of the other features that I like about this product are the aesthetic design choices, the easy filter cleaning and/or replacement and the intuitive and well-designed controls. In addition, the outer fabric covering of the air cleaner serves double-duty as a washable pre-filter, as well as a cosmetic chameleon, due to its availability in numerous “Scandinavian inspired” colors at relatively low cost. There is also a subscription plan available that will supply you with your desired filter types at a reduced-price rate and at apt user-defined intervals. I’m also a big fan of included, quality, paper manuals for products, that have clear illustrations and readable type, as they have done here. The fan noise is, of course, proportional to the fan speed, but is quite reasonably quiet at from 19 to 48 dB per Blueair’s specification. If you need a white noise generator to help you get to sleep, this could be a fairly quiet one at the faster speeds. On the cons side of the equation, I’m not a big fan of permanently attaching a wall wart’s cord to the body of a unit. If there are issues with the power supply, it seems like you’re just creating more work or cost by binding them together, not to mention making it a little more awkward to move. I like this product for the performance, price, features and simplicity. In my use of the product, I did not have any particular air quality issues that needed to be addressed, and my daughter’s cat moved out just as this device arrived, so I was unable to test this in the cat’s sleeping area to see if it helped. However, used in our bedroom, it seems to be doing just fine, as I perceive no noticeable air quality issues and a bonus reduction of dust on furniture. As I have no way to verify empirical data on this unit in a short period of time, I will just have to trust that the specifications were drawn from reliable testing and adequate design. If this model doesn’t seem to fit your room size or other air handling requirements, there are many models in the Blueair lineup that probably will. Seems like a good company from previous product’s awards and all I’ve read.
