- Reviewed in the United States on March 1, 2025Style: Medium RoomVerified PurchaseI 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.
- Reviewed in the United States on June 6, 2025Style: Small Room - WifiVerified PurchaseThis air purifier is quiet, doing its thing. We've noticed our allergies are not as bad since our purchase. It's been running since February (4 months) without a filter change. I've ordered filter refills because we know they'll need to be changed at some point. It's easy to use. Plug it in, and adjust the air flow as desired. It's compact and stylish so it doesn't stand out in the decor.
- Reviewed in the United States on April 26, 2024Style: Small Room - WifiVerified PurchaseI am reviewing the BlueAir 211i Max and 411i Max series in this review as I bought both - one for living room and one for bedroom. Bottom line, these are very impressive units and for the price I am impressed and pleased with each for functionality and effectiveness. I think the aesthetics of it are pleasing as well. It looks nicer than a black box wheezing in your room.
Pros for the BlueAir series. very very quiet. On auto maintenance mode - you can't hear the thing. These are smart machines. You can monitor every aspect of your air quality through the app. You can adjust the control lights from off to bright. It tracks months of air quality data for the room it is in by month, week, day. You can adjust from sleep mode, auto, and 3 fan speeds using the app remotely. It tells you how much filter life is left. It tells you the outside air quality and compares to your inside.
Example of its effectiveness; I was sautéing some Italian sausage and onions, the unit detected the particles and immediately went into high mode for about 5 minutes until all the odor was eliminated and then went back to silent. The front LED bar changes from Blue to Green, orange and red depending on the air quality while at the same time adjusting the fan speed to address the corresponding level of air quality indicated. Same thing happened when smoking some meat on the back patio. I left the door open to bring in the food, the unit detected the smoke and the front LED went red. After closing the door, it ran on high mode until the LED indicators began to regress back to blue and the fan speed decreasing accordingly until all the smoke odor was eliminated from the room.
Cons for the BlueAir product. It is a bit pricier than other options - but for all the differences - so far, I feel the Blue Air product is definitely worth the price difference, for me at least.
What I have not addressed: the longivity of the products; the life of the filter; ease of maintaining; Both of my purchases are within the first month;

5.0 out of 5 stars Big help
Style: Large RoomVerified PurchaseVery effective, works well and easy to use. This purifyer is helping me everyday from nasty allergens from cigarette smoke. I just moved into a building with big smokers and poor ventilation. I knew about my cigarette allergy but I hadn't known how severe it had become. This purifyer is ideal for all kinds of smoke, from cigarettes to forest fire smoke, because it has a carbon filter. I leave it in automatic mode and it filters the air using very little energy to keep the air to "excellent quality". There is a light that changes color to inform us of air quality. When it's blue, I know I can breath easily. You can hook this purifyer to your Wi-fi and use special app to manage it, but it's not necessary. I'm using it without it and it's going very well. It's very quiet compare to my previous one I bought 3 years ago. The filters aren't cheap and it needs to be changed every 6 to 9 months. I haven't had to change it yet, but I'm hoping it lasts as long as possible and that there won't be any problems. I'll edit this review when it's time for a change.

5.0 out of 5 stars Quiet. Cool interface. Looks nice. Really happy with this air cleaner.
Style: Medium RoomVerified PurchaseGreat machine. You pay for the quality but it's quality you get.
I use it in my bedroom for allergy season. On night mode, it is impossible to hear. On level one, you can barely hear it. I keep it on level one. Automatic works well - the speed increased when I had a smoky air fry. The design is nice, and well thought out. The fabric prefilter is super easy to remove and wash.
The Bluetooth connection works well and it's nice to see the current and history of how clean the air is.
There are no cons here. Great unit.

1.0 out of 5 stars Not recommend for smokers, not recommend for pet onwers
Style: Small Room - WifiVerified PurchaseIt doesn't detect and purigy the smell of smoke. Not good for pet owners.
I am a tenant. My roommate is my landlord and he smokes cigarettes and maxxxxxna in his room every day. I can smell his cigarettes in my room. I thought buying an air purifier would make a difference, but I was wrong.
I placed my blue pure 411i Max in my room, set it on auto mode, and keep it working for a week. During this week, I discovered that many times, even though my room smelled strongly of smoke, it was still running on minimal power. It cannot effectlively detect and purify smoke. I need to manyally adjust its wind power.
The child-proof lock design is terrible. Even I set the child-proof lock on, the air purifier can be eassily turned off by pressing the power button. Child-proof lock only prevents changing the wind speed. The cat can turn it off. Also, cat sometimes plays it as a scratcher.
This air purifier has a built-in pm2.5 sensor. It can detect pm2.5 and adjust the wind speed. Smoke odor is mainly from pm10. IMPORTANT! If the indoor PM10 is high but the PM2.5 is low, then this air purifier will run at the minimum power. I don't know how much the additional cost would result from adding a PM10 senser. I really don't understand why the product manager designed it this way.
This air purifier is really beautiful. It looks like an art in my room. I also feel impressed by how quiet it is. At level 1 mode, I can barely hear it working. When it's in sleep mode, I can't hear it working.
If no one smokes in the house and you don't have pets, then I would recommend it. It is quiet enough and pretty enough.
