I 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;

Great product. It was recommended by my allergist, I have very bad allergies and this works real well. Easy to set up and operate. I can monitor it's function on my phone. Easy to clean and replace the filter. It is very quiet and air flow is very good. It has a sleep mode at night, so it won't disturb your sleep. Good value.

I've been using this filter for a couple of weeks. I live in farm country and this year I had very serious allergies requiring serious medical intervention. This filter was an experiment to see if I could create a safe space to hide from the dust and other farm junk in the air. No surprise the filter works quite well. This is more than an anecdotal comment! The filter is smart and I can follow the air quality via cellphone. When the air is within cleanliness limits the fan silently runs circulating air, when it detects a rise in particulates it speeds up. It was interesting to note that it even detects when I'm cooking in the kitchen in the next room, it speeds up and displays the resultant rise in particulates on my phone. No, I wasn't burning anything nor could I detect smoke of any kind while cooking AND I have a range hood that exhausts outdoors. Pretty impressive IMHO. BTW, I can force the unit to run full fan speed and it's a bit noisy but it never seems to go that fast on auto. While I haven't had to replace the HEPA filter yet, I bought spares and the replacement procedure looks like a breeze,

I have purchased two of these and overall I like them. It was a little challenging to register the product. I first tried on their website which didn't work right but it allowed me on the app that I had downloaded onto my phone. The units work well and are fairly easy to set up. It works through the app as well as from the unit. Mostly I use the console on the unit if I want to change anything. It doesn't look difficult to change the filters. The inside one is a little pricey if you want the more hypoallergenic filter. However filters seen to last around six months. The controls are easy to use. The hardest thing was to adjust the dimming of the light which was a little tricky before I got it. It is not clear whether to run it on the automatic setting or use the fan for faster air exchange. I find the information offered not that detailed. I have taken to running in on the "2 fan blade" setting (low medium?). My only complaint is about running them on the two higher setting. In both one has a mild "buzzing sound that won't go away. And the other has a mild vibration such as fan bladed not being quite balanced. But since it doesn't really seem necessary to run at the higher speeds, it is not a big issue. At the lower setting it is quiet. Being large they are somewhat unwieldy to move around and as such I bought roller caddy's like for large plants which work well. Lastly

I'm not sure what other people's problem is with this filter. As soon as some cannabis or tobacco is lit the meter turns red and then cleans the air, simple as that. An added bonus, it works great as a white noise generator if that's your thing. I usually put it in the bedroom on level 2. 1s to quite, 3s to loud my ears ring like a bitch, this helps at bedtime. I'm not sure what people are thinking if they believe this will remove the scent from a room that's had a cat pissing in it for 5 years it's not going to happen. Works very well for smoke and general odors. You can always spray a scent on the outer filter it distributes it well. Honestly, I love this thing.

Very happy with this puifier. It works well and picks up smell really quickly. Within minutes your air is back to 0. Very pleased with it. I would recommend getting one. Easy to set up and get it started. Not very noisy.

Play Video En si estaba con todas las ganas del muy para tener un purificador en mi cuarto ya que siempre le entra humo de los demás que queman cosas, en si la experiencia en la aplicación es buena pero a la hora de encender el purificador suena como un grillo o interferencia de un televisor viejo que en primera estancia me saqué mucho de onda, la única forma en la cual ya no se escuchaba eso es que le subiera la intensidad del ventilador pero ese no es el punto de tener el producto…. Me dio mucha pena llevarme tal decepción y tener que regresarlo

Good deal! This air purifier works very well for large rooms and significantly improves air quality. The HEPA Silent technology is efficient, and it's relatively quiet, which is a big plus. However, the app integration could be more user-friendly, and replacement filters are a bit pricey. Overall, it’s a solid product that delivers clean, fresh air effectively!

It is a very large machine (I didn't appreciate how.largw it is), contemporary and upscale looking due to limited plastic showing, and extremely quiet even on fan 3 of 4. The app shows air quality and you can control it. So far I am happy with it compared to my other units. On sale it was an excellent value

All LEDs just stopped working one day. Called customer service and was talked through how the dimming feature works. Great customer service! It’s a simple unit and works well. I would recommend reading the instructions thoroughly and testing each feature out as they are not intuitively activated with only two buttons. Lots of holding and tapping.
