BLUEAIR Air Purifiers for Home up to 2,107 Ft², Blue 311i Max | WiFi, Auto Mode, Quiet 23dB HEPASilent Filtration, AHAM Verified, Washable Pre-Filter, Captures Pet Hair Allergens Dust Smoke

★★★★★ Noticeably Cleaner Air and Whisper Quiet After using the BLUEAIR Blue Pure 311i Max Smart Air Purifier for several weeks, I can honestly say it’s one of those purchases you don’t realize you needed until you have it. The first thing I noticed was how quiet it is. On the lower settings, it’s barely noticeable, making it perfect for a bedroom or living room. Even on higher speeds, the noise is more of a gentle white noise than an annoying fan sound. The setup was quick and easy. Connecting it to the app took just a few minutes, and I like being able to check the air quality, adjust settings, and set schedules right from my phone. The Auto Mode does a great job of increasing and decreasing fan speed based on the air quality in the room, so I rarely have to think about it. Within a few days, the air in our home felt fresher. We noticed less dust collecting on surfaces, and family members with seasonal allergies commented that they were waking up less congested. The unit also handled cooking odors much faster than expected. The only downside is the cost of replacement filters, but that’s fairly standard with quality air purifiers. Considering its performance, energy efficiency, and smart features, it’s a trade-off I’m willing to make. Pros: * Extremely quiet operation * Easy setup and intuitive app * Effective Auto Mode * Helps reduce dust, odors, and allergens * Attractive, modern design * Energy efficient Cons: * Replacement filters can be a bit expensive Overall: 5/5 stars. If you’re looking for a reliable smart air purifier that actually makes a noticeable difference in your home’s air quality, the BLUEAIR Blue Pure 311i Max is an excellent choice.

So far, we are very pleased with Blue Air! We purchased a Pure 211i Max for our large living area and a 311i Max for our master bedroom. They both work really well and we leave the 211i on Auto and both are quiet. If you vape or smoke, it kicks in very high for a short time then returns to a very low operating state. We program the 311i to maximum speed at night for sleep noise and love it. We've noticed a lot less dust and our house smells better too. These units get a good rating on Consumer Reports and they appear to be very well designed and made. Easy operation, just wish the filters were a little cheaper, but you get what you pay for. Highly recommend Blue Air!

The BlueAir purifiers are the best looking on the market, and they have the tech to match. I love the app – being able to track your air quality like that is fantastic. This is my larger/main unit positioned in my living room/hallway area where a lot of airflow and foot traffic is, and it's fantastic. It's the only purifier on the market I've seen that I don't mind having in my living room because it looks clean and sophisticated. The auto mode is soundless, which I LOVE, and even when you crank the fans up, it's not loud or bothersome whatsoever. Definitely one of the most premium options on the market in both looks and operation. Works great at removing dust and keeping the house fresh. Love!

We live in the treasure valley area of Idaho that has been experiencing a high amount of smoke (aqi between 150-400 for three weeks now) and we have two young asthmatic children. This cleaned the smoke out of our house (outside air comes in through vents on the second story that are unreachable due to building codes) within a day. Not only this but our house now smells like nothing. With three children and a dog I gave up trying to make the house smell either like nothing or “good” years ago. No matter how much I cleaned it was there. Food, trash, mud, kids, spills, dog hair, wet dog smell, stinky dog breath. All the smells. Gone. One did a good job in our 3600 sq open concept two story home but struggled in the two story foyer. Bought a second one and have no regrets. This one is also much quieter than the smaller levoits we have in the bedrooms

⭐️⭐️⭐️⭐️ 4 out of 5 Stars “A Game Changer for Our Living Situation – Just One Small Flaw” This air purifier has truly been a lifesaver for our family. We’ve been living in a hotel room with our kids for the past two years due to the rising cost of living, and having clean air in a small space 24/7 is essential. This device has made a noticeable difference in our room’s air quality — we use it constantly. What we love most is the app integration. It alerts you when it’s time to change the filter, gives you updates on your air quality, and even allows you to order replacement filters directly through the app. That kind of convenience is priceless for a family like ours. The reason I gave it 4 stars instead of 5 is due to one design issue. Our toddler — who’s almost 3 and full of curiosity — managed to drop a pen into the fan area. It chopped the pen in half and left ink everywhere. While we were able to remove the pen and clean it, the real challenge was getting to the fan mechanism. It required removing screws and disassembling part of the unit, which felt out of place since the rest of the design is very user-friendly. If there’s one suggestion I could offer the manufacturer, it would be to make the fan compartment more easily accessible for maintenance, especially for families with small children. That said, we absolutely love this purifier and highly recommend it to anyone who needs reliable, round-the-clock air purification in a compact space. It’s been a game changer for our home away from home.

Owned this for nine months now and just replaced the filter for the first time. We have a large house with old carpet, and a dog that sheds a lot. I love this air purifier every. day. I am overstimulated by sound VERY EASILY, and this purifier is quiet enough at fan speed 1 that it never bothers me. And it has a night mode that is even quieter. Fan speed 2 and 3 are a little louder of course, but not obnoxious. Sounds like a small 3-speed circular fan like you turn on in the summer. My favorite thing about this purifier (besides how well it filters the air, which is noticeable because old-carpet-and-dog smell doesn’t hit guests in the face) is how WELL MADE it is. They paid attention to the little details when they designed this- I mean they sewed HANDLES onto the filter to make it easier to take off. This is a lifetime product. You can easily disassemble it, the pre-filter is machine washable so you never need a new one, and the replacement filter was only $40 and I got NINE MONTHS out of my first one. As you can see in my video, the filter really works. There was even loose dirt left behind at the bottom. They put instructions for replacement on the new filter box, but you can also find info in the app. The app is also so helpful and easy to use, you can customize the machine by setting schedules or dimming the brightness of the controls, and it keeps up with your filter life and air quality readings. If you have an old house, pets, kids, or you just really like clean-feeling air, I cannot fathom a better choice.

My eyes no longer water indoors and my place actually smells cleaner if that is possible. This time of year is very bad for me with my seasonal environmental allergies and I have to say I am not sneezing and my eyes are not watering as they usually do when I'm indoors. And I'm a little scared to say it because I don't want to bite my head off, but my migraines seem to be less as well. It just has a different feel all together inside my house and I love it. I bought two units one is in my main living area and one is in my bedroom. They are nice looking they don't stand out with this big white hard plastic unit I love the way they paid attention to design when they made this. I have not gotten around to fiddling with the settings yet but I will do so and if I have any problems which I do not expect, I will update my review but as of right now go out and buy this! There is so much junk in our air these days this is a game changer. Go get it.

I purchased two of these Air Purifiers in April of last year (currently February, ~10 months later) and am extremely pleased with the results and effectiveness of the product. I live in Brooklyn, NY in a railroad style apartment (one side facing street near-ish a busy road, the other side facing an interior courtyard) and I purchased two 311i Maxs. One is in the the threshold between the kitchen/living area and bedroom area and the other is in the main "bedroom" that faces the street. The threshold between rooms is high traffic, so lots of dust and particulates get swept around when I walked between the rooms of the apartment. Immediately I noticed that the dust accumulation in the living and bedroom area became much more gradual. The purifier itself also traps a TON of dust clumps on the cloth outer filter that needs to be cleaned periodically but I am happy to know that it is certainly doing its job. The bedroom purifier also is doing well, but its a much lower traffic area of the apartment so it doenst need to be cleaned as often. The advertised filter live is 6 months. However, after 10 months the high traffic air purifier's filter is just about at 15% and I purchased a replacement. For context, I run it constantly at its lowest setting and have it automatically adjust to a medium high setting for two hours each evening from 5-7pm (this is usually when I am cooking and honestly, not even sure if this is necessary). I am extremely impressed with the durability of the filters in this capacity. Noise wise, I couldn't be happier. They certainly have gotten marginally louder over time (likely due to filter age) but really not bad at all. My (aging) refrigerator's cool cycle is louder than these things. I'm an audio engineer so I use my ears for a living and am particularly sensitive especially when I am working or trying to go to sleep. Not only is the purifier's noise imperceptible from more than 10 or so feet away, but I have on running all day in my studio where I work and I don't have to turn it off except to record exceptionally quiet sources. To be fair, this is all on the lowest setting. The higher settings are certainly noticeable, but about the same volume as my Mideas air conditioner. The app also works great. When there was renovations happening in the apartment below mine, I was able to periodically check in on the particulate levels while I was out for work and adjust the purifiers intensity as needed to make sure no unwanted drywall or wood dust settled in my apartment. The indicators on the units are helpful as well to see the air quality change when cooking or lighting...erm "incense" and know that the purifiers are doing their job and keeping the house clean and odor free. You can have the filters auto-set depending on particulate levels but honestly, they work so fast at the lowest setting I rarely find myself manually upping the intensity of the fan unless there is a serious cooking/smoke mishap or something similar. You're probably better off just keeping them on low 90% of the time. Recommend these to folks all the time as I do to you, dear reader.

I purchased this air purifier to supplement a larger Blueair unit (211i MAX) have for cleaning the majority of our 1171 sq ft condo. This purifier sits in the main hallway to cover areas the larger Blueair unit does not. The setup was fast out of the box. Wi-Fi is enabled, so it was just a case of adding it to my BlueAir app on my phone and connecting it to my home network. The device provides detailed air quality readings on the app and can be programmed for on/off schedules, display brightness and air filter life; the latter is important to know when deciding to reorder new filters. Maintenance is quite easy: each month, I vacuum the outer pre-filter and open the unit (turn power off) to vacuum the filter chamber. The app will advise if the pre-filter needs cleaning. There is a geofence option [called 'Welcome Home', to turn the purifier off if you are away at least 3 km and turn it on within the radius. The unit is well-made and does the job and why I purchased a second unit.

Love this! I just started using this a month ago and it's already made a huge difference with the smoke from the wildfires. Prior to setting this air purifier up my home was filled with smoke on low to high air quality days. Now, I don't even notice the smoke until the air quality is high and then the smoke still does not bother me. I purchased this because of other smells from laundry, BBQ's, and dumpsters in the back lane and I seldom notice these anymore. I'm so glad I bought this Blue Air 311 purifier! I have had it on high and it is relatively quiet - almost soothing. I don't even notice it and it does not cause sleep disturbances. Easy to set up and maintain. Well worth it!

I've only had the Blue Air 311i Max for a week but I am so impressed! it is whisper quiet, I can't even hear it and it's right beside me while I'm working on my computer. you can hear the fan on the highest setting but you wouldn't run that setting for long. Good for a larger room space I use it in my living room kitchen open concept and I do notice a difference, especially with the forest fire smoke. it is larger than I thought, I included a picture for reference.

Update#1: Here we are about 11 months in and this unit has developed a couple of annoying glitches. It still performs its primary function well. It has developed a slight, but audible, buzz or humming sound on fan speed three. The air quality sensor is unreliable rendering the auto function non-functional. Very happy with this air purifier. It has successfully handled smoke from wildfires over the past two years.

My husband has seasonal and dust allergies, and suffers with some pretty considerable symptoms every day, year round, and this brand was highly recommended. I'm glad I chose the 311i Max model which can clean a much larger space, such as one floor of our house. My husband experienced an immediate improvement in his symptoms. The app is helpful. I love being able to track particle levels in our home, and it's amazing how closely my husband's symptoms track with the pollutant levels it displays. I see big spikes on the app display whenever our air conditioner kicks in - then my husband's symptoms gets really bad for a little while until the air clears. So the app display helped us understand that we need our vents cleaned. I'm not sure I love auto mode. I've got to watch it more closely for a while to be sure, but I don't know if it really speeds up the fan fast enough when there's a spike in indoor pollutants. Overall I love it though. It's improved our lives. There's so much less sniffling, sneezing, coughing, and watery eyes. We now drag this thing to our bedroom every night, and to our main living space every morning, so I'll keep an eye out for a good sale and likely get a second one.
