Well you want it like it is here it is. I buy based on this very thing and I usually don’t leave reviews because my complaint or issue is known going into it so I get what I’m paying for and deal with it on me. In this case I’m taking the time which happens about three times a year on a product to leave feedback. This filter unit I’ve had for about 1 hour and I can honestly say l is FANTASTIC. I opened it and was like…wtf it’s a giant towel wrapped filter with Wifi capabilities for 200 plus bucks??? WHAT???Plug it in and let it eat the air and all it has to carry in it. Within minutes of plugging it in you can literally feel the difference in the space. It cleans the air fast and quietly on lower settings and does the whole house within reason after about 45 min. I mean the smell of cooking, pot smoke, pet dander while vacuuming afterwards etc. Machine senses it and goes to work and takes care of it. Great for a small house/apartment/conso as mentioned on specs but it covers this place I’m in great. Again I did buy it knowing this and it’s exceeded all of my expectations. I will return and add to this review once I change the filter see what the power usage will be like on my settings etc. I’m a tough sell but I got this after cooking and smelling chicken parm for three days. Just a fantastic unit it literally senses the pollutants and in the app you can see the levels and it explains each type of PPM which is cool. App is nice and easy use so far. High recommended this product.

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;

This works well, easy to see air quality by indicator light and phone app. I’ve seen it quickly react to candles and cooking. Air smells clean. Easy to set up and use. Repeat buy- I have 3 in different spaces.

Really like this air-purifier. It clears the air very quickly and is quiet. I plan to get a smaller on for my kitchen.

I learned about this air filter on Wirecutter, as I imagine many others have. It works great. There is a LED screen that shows the ppm of particles in the air. I run it on Auto, so it adjusts the output based on how polluted the air is. There is a handy app that tracks air quality and allows you to control the device remotely. It is an attractive design as far as air filters go and non-obtrusive. I like it better than my Coway Cube that I’ve used previously.One important note: on the BlueAir website, they offer filters of varying filtration abilities. So if you want a filter that grabs smaller particles, then I suggest purchasing one of the upgraded filters on the website. They offer a subscription discount also which knocks off a decent percentage. There is a fabric “prefilter” that traps the larger dust particles and dirt/debris. It can be removed and washed. They also offer different color fabric if that’s your thing.These are fairly pricey purchases but I’ve found that they go on sale regularly also. So it may be worth waiting for a sale if you can be patient.

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,

Seems to make the air crisp
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

Muy decepcionante
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

Really Works to Clean the Air
This is a great product. It really works well. We bought it to clear wildfire smoke and we are really pleased about the clarity of the air in our home. The app works very well and it is easy to use. Provides air quality feedback and information, tells you about particles in the air and has several options that help optimize the effectiveness, adjust the fan speed etc. It is not loud but also has a night mode. Truly helps my breathing.

Simple, effective air cleaner
This does an efficient job in our bedroom without a lot of bells and whistles. But we haven’t had any wildfire smoke this year to really test it. Quiet, even on the highest setting (but we don’t mind the sound anyway as it’s “white noise” to us). I haven’t tried the app yet because it just doesn’t seem necessary. My only issue is around registering the warranty. A QR code on the instructions is supposed to take you to a warranty page but instead it’s just a general BlueAir website. After some frustration I had to contact BlueAir support to get the warranty registered.
