Customer Ratings & Reviews

This air purifier is amazing. We have kids and one has asthma and terrible seasonal allergies. This time of year always means more cleaning and extra vacuuming but it's still a struggle to reduce his exposure to allergens. I can confidently say this has made a big difference in just a few days. Setup was super easy and the app connected quickly and without a ton of hard to follow steps. I love that you have a graph and can physically see when and if changes to air quality are happening. You can look back through previous hours as well if there were spikes in the air quality and you want to monitor it and your home. I really liked that we could set up different profiles or time slots for running your purifier. Right now we have it set to run when we are all home and all night. I've noticed we are sleeping better and all of us are sneezing less even with sleeping with windows open. I love that the prefilter is washable and you have the option to sign up for shipments of the filter as needed. This was super easy to use and set up for our families needs. I'm looking into the next size up to put in the living room now and we will be using this one specifically by our son's room and the play area. I highly recommend this to anyone looking for a cleaner environment and easy to use controls.

This air purifier has a modern attractive aesthetic but the performance is nothing special. Even though they call it "HEPAsilent" it seems just as noisy to me as any other air purifier I've had, so don't buy the marketing on that. To me the fan also seems a bit high pitched and shrill at higher speeds compared to other air purifiers I've had. At very low speeds it is quiet, but it's also barely moving any air so it's hard to count that. The app is a neat feature to have and seems to work great.

Air purifiers have become “the new thing” ever since the pandemic I feel like. Lots of air purifiers with varying levels of purification ratings, and the Blueair does not disappoint. It’s essentially hospital-grade because it’s rates to catch even airborne viruses with the HEPA filter. For our home, all of us, including our two kids, have terrible allergies. And where we live, cedar and oak are basically active all year long. So we have had to put purifiers in every room. So our experiences with different purifiers is based on real world actual data (my kids being able to sleep at night). Hands down, the best feature I’d the Blueair is that it is quiet. Not a “quiet” if you run at the lowest fan speed, but truly quiet. Our room doesn’t sound like a jet engine at night. In addition, the brightness of the lights are dimmable! Why other companies don’t think that a glaring bright blue/white light blasting in the room is okay is beyond me, but that was a common complaint with other filters because my wife is a light sleeper and sensitive to light. I set the filter to auto, and I haven’t had a sniffly nose at night since. Cant recommend enough.

I have really bad allergies, especially during the Spring and early Summer, so I have quite a few air purifiers from different brands around the house. When I got a chance to try my first Blueair air purifier I had to jump on it. Here’s my review of the Blueair Blue Pure 311i. I’ll give you my overall impressions first and then break it down a bit. Overall I really liked pretty much everything about the Blueair Blue Pure 311i. It’s a great air purifier for small to medium-sized rooms. It's pretty simple to use, has a nice design that would blend into any decor, and can operate very quietly. It also has HEPASilent technology, which traps 99.97% of airborne particles. If you're shopping for an air purifier, the Blueair Blue Pure 311i is a solid choice. The Blueair Blue Pure 311i is a wonderful air purifier for small to medium-sized rooms. It's a breeze to use and has a sleek, modern design. I personally enjoy the ability to set the unit on quiet mode if it’s located in a living room but also can turn it on high if I want some white noise in a bedroom. The Blue Pure 311i advertises something called HEPASilent technology, which claims to trap 99.97% of airborne particles, including dust, pollen, pet hair, and other smaller particles. The pre-filter is there as well and that takes care of the larger particles before hitting the HEPA filter. The air purifier has a CADR rating of 150, which basically means that it can clean the air in a 150-square-foot room up to 5 times per hour. This rating is only true when it’s operating in full speed mode though, as sleep mode will be quieter but not clean the air nearly as quickly. As with any air purifier, you’ll need to replace the filters on the 311i occasionally. Blueair recommends replacing the filters every 6 months, but I usually use these a little longer as I clean them with my vacuum every couple of weeks to extend their life. Also, I wasn’t able to find filters for the 311i on the Blueair website as of this review, but based on their other similar air purifiers the filters are a bit pricey. Pros: -Simple operation -CADR rating of 150 -Sleek, aesthetically pleasing design -HEPASilent technology -Can operate quietly Cons: -May be too small for large rooms -Filters look like they may be pricey

Quiet and great at dust particle reduction thank you

Nice and quiet and very effective in the bedroom. The app makes it easy to see when there’s more particles in the air and how well it was removed.

One of the standout features of the Blue Pure 311i is its straightforward setup process. It comes with clear and concise instructions, allowing users to assemble the unit within minutes. The filters are pre-installed, eliminating the need for any complicated filter installation procedures. The compact and lightweight design of the Blue Pure 311i further enhances its ease of installation and use. The unit's portability and versatility make it adaptable to various room sizes and layouts. The Blueair Blue Pure 311i air purifier boasts an intuitive control interface, making it very user-friendly. Located on the top of the unit, the touch-sensitive control panel offers a sleek and modern aesthetic. The panel features easy-to-understand icons and functions, ensuring effortless operation for users of all ages. The purifier offers three fan speed settings: low, medium, and high. Adjusting the fan speed can be done with a simple tap on the control panel, allowing users to customize the airflow according to their preferences and the level of air pollution in the room. The display also provides real-time feedback on the indoor air quality, thanks to the inclusion of a color-coded indicator. This feature enables users to monitor the effectiveness of the purifier at a glance. One notable aspect of the Blue Pure 311i is its whisper-quiet operation. Even on the highest fan speed setting, the noise produced remains minimal, allowing for uninterrupted sleep or work. The lack of excessive noise makes the unit ideal for bedrooms, nurseries, or office spaces where a peaceful environment is crucial. The unit comes equipped with a combination particle and carbon filter, ensuring the removal of airborne pollutants such as dust, pet dander, pollen, smoke, and odors. The filter's lifespan varies depending on usage and air quality but typically lasts around six months. The process of replacing the filters is straightforward and can be done in a matter of minutes. The purifier's top cover easily lifts off, providing access to the filters. Once removed, the old filter can be replaced with a new one by simply placing it back into the unit. The filters are readily available and can be purchased directly from the manufacturer or authorized retailers. To maintain optimal performance, it is recommended to vacuum the outer surface of the filter periodically to remove any accumulated dust. This simple step enhances the filter's longevity and ensures its efficiency in capturing airborne particles.

Great air purifier, quiet and efficient. I love the application that shows when you need a new filter.

I've been using room air purifiers for years to help with my allergies. I've always owned the HEPA-type with the carbon and paper filters. Filter replacement was always expensive, so I went looking for a less bulky, less costly brand. Back at the beginning of the pandemic I purchased my first Blueair filter and have loved it ever since. I immediately noticed the effects on my sleep, how I slept better, longer , uninterrupted and felt more fresh in the mornings. I LOVE the all-in-one filter. It's so affordable and easy to replace. I love the fabric cover/pre-filter. So simple to vacuum or even throw in the washer. I love how quiet this is on the lowest setting. The medium setting might be too loud for some at night, but it's much quieter on medium than other air purifiers I have owned. The high setting is loud, but it's great to leave on all day when you're at work. If you close the door and leave it on high all day, when you come home you can actually smell the freshness of the room. If you have allergies, asthma, or share walls with a smoker next door, you very much need to buy BlueAir. I also love how the light at the top turns red when it's time to replace the filter. Some of my old models had filter indicator lights that stopped working after 6 months, so after that you're just guessing about when to change the filter. BlueAir has such a simple, logical, efficient design including the integration of the app which allows me to make adjustments and monitor the quality of the air. This thing truly has been amazing when it comes to the most important thing to me which is good sleep. I almost hate when I have to travel away from home because I will be without my filter.

Works great! Not too loud. I have noticed an improvement in my daughters allergies since using this.

Very easy to setup/use and is whisper quiet. It is a nice looking purifier for the room.

I just love this air purifier it keeps the air fresh

Easy to setup, runs very quiet. The automatic setting is ideal forour setting

We love the auto feature as it kicks on by itself when cooking odors are strong
