- Reviewed in the United States on April 26, 2024Style: Medium RoomVerified 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.
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;
- Reviewed in the United States on January 4, 2025Style: Small Room - WifiVerified PurchaseI love these things. I have this larger one and have bought 3 smaller ones. I love the wifi set up and I love the auto setting. Super quiet and then one morning my wife was cooking bacon and the auto kicked in and ramped up to high to clear the air. Tells me the sensors really work and doing their best to keep your air clean. Also gives you status of filter cleanliness and when to change and air quality throughout the day. I’ve got them spaced out in my two story home and very happy and pleased I got these. These combined with my electromagnetic air filters and blue light in my HVAC unit, I know I am doing their best I can to keep the air in my house clean. Loving it.
- Reviewed in the United States on August 26, 2020Style: Large RoomVerified PurchaseInitial impressions of this purifier are very positive. I'm not setup to test the actual purification abilities beyond an anecdotal indication that it seems to clear the air well. See the reviews on Smart Air (they think it works very well but is over priced), Consumer Reports (the 211 and the Classic 605 are their two highest rated units), and elsewhere. BlueAir is very well regarded in terms of actual cleaning effectiveness.
For all the other features, here are some of my key decision points and useful tips:
First, I bought both a 121 and 211+ - they have similar specs, except the 121 has a 400 CADR rating rather than a 350 for the 211. I was a bit surprised to realize that they appear to have identical motor and fan units - you can swap them back and forth, and they measure identical power consumption, and sound the same. This means the 121 gets the slight boost by simply being taller and holding a larger filter. More filter area would make for more efficient filtration, and a small boost in CADR rating.
This isn't really a knock, it is just worth noting if you are considering both units. I would say the 211+ is the better value in this regard, the 121 is over $120 more expensive, has $20 more expensive filters, and only slightly more filtration capacity. If you need something just barely over the 211+ in filtration, only have space for one unit, and have a large open space, then the 121 makes sense. Otherwise, if you need more than the 221 provides, and you have a space that isn't just one big open room, then buy two 211+s - it is still a better value than most of the other comparable units, and two small units will filter an uneven space better than one loud one.
As for noise, these are both very quiet units (same noise, because they seem to have the same fan). The background noise in my house measured at 38dB, and I measured on an iPhone running DecibelX, A-weighted, at 1 meter from the unit, horizontally, mic pointed at the unit.
- Low - 39dB, just barely over the background noise. It is not obvious that the unit is even on.
- Medium - 48dB, I can tell that it is on from around the room, but only if I listen for it.
- High - 55dB, OK, now it is making some noise, but it is soft in tone, not rattling or whining. Still reasonable in volume, and easy to talk over. It wouldn't kill your conversation and if you sleep with a white noise machine it might actually be similar volume (our DreamEgg at mid-high volume is about this loud).
Power consumption is as indicated on the package - 30W, 43W, 62W, as measured by my meter. Quite reasonable again given the ~400CFM the fan must be blowing.
Small things to appreciate:
- The unit is attractive and simple. It doesn't look like a weird 90's appliance with a bunch of random protuberances or shiny stickers. It is clean and Swedish, and would integrate with a lot of decor. The changeable pre-filters come with a light blue and a midnight blue, and you can buy others. Looks fine without it as well, pure white.
- The overall construction is simple and sturdy - a metal box to hold the square (but flat folding) filter, and an upper box with the controller and fan unit.
- Upward blowing and pulling from all sides makes for a lot of filter area - units that just pull in the side or front are going to have a lot less filter area for the same air flow - meaning more noise.
- The button on the front is capacitive - touch to change between off -> low -> med -> high -> off. It is sensitive and easy to use - I change it with my toe while holding a baby.
- The unit remembers the last setting if the power is removed and restored. This means you can use it with a timer or in my case, Home Assistant automation!
- The LED showing the current speed dims to 10% after a few seconds - very nice - I'm usually forced to put black tape over everything I buy to dim the bright LEDs everyone uses.
The unit does not include Wifi (pointless and risky), particle counters (not going to be accurate at these price points), a display (why does it need one?), or an auto mode (read the articles on Smart Air about auto modes - they are mostly useless and sometimes much worse than just setting a moderate level and letting the unit run all the time). Basically it has everything you want - quiet fan, large filter area, easy buttons, and nothing you don't want.
It isn't the cheapest unit, but it isn't the most expensive either. Compared to very cheap units you get a quieter fan and a more proven filter technology from a vetted company. Compared to more expensive units you lose some (mostly useless) control features, and some options for multi-stage filtering or chemical canisters like you might see from a (8X the price) IQair. My inlaws have a Blueair Classic 605 and this unit is smaller and quieter, for only slightly less filtration capacity, at 1/3rd the price.
All in all, an easy recommendation if the filtration capacity meets your space needs.
- Reviewed in the United States on December 22, 2022Style: Large RoomVerified PurchaseBefore I purchased this size/make I did some research and Consumer Reports has this listed number 3 in its top 5 of household air purifiers. It does almost as good a job as the top 2 according to Consumers Reports. The reason it landed in the number 3 spot is because it was not as energy efficient as the top 2, but for the year it was only a few dollars more to run. This air purifier is a much better deal in my opinion because the #1 ranked air purifier was priced $795.
It is very very quiet on speeds 1 and 2. And on speed 3 it sounds very similar to a small tabletop fan on low. I use it in my 12'x14' bedroom and the fan does not affect my sleep. In the pictures it looks as though it's a small unit but please note the measurements, it is fairly large and bulky. Although it is very lightweight and easy to move around, or lift. It does a somewhat sufficient job of removing smoke odors coming from the tenant below me, but not 100% at eliminating ALL of the smelly stink from constant smoke etc. If you need to remove strong consistent odors I don't think it would be work well in a larger room regardless of what the description states. This is a very economical purchase for a large air purifying unit. I would recommend it as a room size unit, but not for a whole house.

5.0 out of 5 stars Breathe Easy - Blue Pure 211+ Air Purifier Works!
Style: Large RoomVerified PurchaseBlue Pure 211+ Air Purifier is an amazing product! There’s almost zero assembly required. You unbox, put the washable outer filter on, you plug it in, and tap front button to turn on to start. Within 15 mins of it being on in my room, immediately I noticed how light and fresh the air is. There’s no unpleasant scent at all other than the new filter smell which doesn’t bother me. After 1 1/2 weeks of using it, this new filter smell is gone and it’s just fresh air. I love it. It gets rid of cooking smells too. I love cooking fresh fish often, and man, this purifier eliminates the odour within an hour compared to 3-4 days of lingering fish smell inside of the house. No more opening windows in the middle of winter just to air out odours. Noise Level is appropriate and can be tolerated. First level of air option is very quiet and almost no noise. Second level option you can hear the fan but sounds like a subtle white noise, Third level of air option, strong fan noise but man it’s very effective! Manoeuverability is easy. I like that the button to turn on the purifier is tap sensitive. The machine could use a nook for the hands on the sides for easier to move from one place to the other. There’s a warning label on top of the machine to carry the machine from the bottom when moving or carrying. The fan on top is connected to the filter at the bottom. There’s a locking mechanism between the two chambers, but I don’t feel it’s a sturdy lock and agrees that it’s safer to carry from the bottom and not from the sides of the machine. Weight is light for younger folks but I don’t recommend grand parents to carry the machine on their own. Overall, amazing air purifier!
