I chose the Blue Pure 311i Max to replace my older model BlueAir Filter. The new filter can connect to Wi-Fi for remote app control. The app seems to report the air quality on a chart, but so far, it's saying my existing air is "Excellent," which may be because it replaced the existing filter, which was also doing a decent job. However, some PM 2.5 was detected in the room (PM2.5 is "Fine particles", such as "fine dust, exhaust, bacteria, and pet dander"), so it's working already. The app controls Fan Speed (lower speeds are quieter/silent, higher speeds filter quicker), Automatic Mode, Night Mode (extra quiet and dimmed lights), and a child lock function. Of course, the app will tell you how much life is left in your filter as well - and yes, the device has a filter warning light on it; however, the app may let you know how close you are to that 'replace filter light' coming on. The app has a welcome home feature to filter the air as you get closer to home, but you have to make sure you give the app (1) background location permission, and (2) unrestricted battery (no optimization). My previous blue air filter did not have Wi-Fi features, so this is a nice upgrade. I will tell you immediately there is a different quality in the air and a different feel in the room on the first day of its running. I feel more relaxed (my skin even) in this room than before I replaced it. There was previously only one or two other places (outside the house, such as other businesses) where my skin had this relaxed feeling, probably because of good filtration there (I suspected). Now I have it at home. Time will tell if this remains true or if it's just like a placebo effect appearing because I was hoping for something like this. Most air filters work best in a room with closed windows because, with open windows, you are filtering outside air with an endless supply of allergens. In reality, most of us do occasionally open the windows, especially (in my case) in fall and spring (which may be the worst time for allergens) when temperatures outdoor are nicer. It's unclear if doing this will shorten the filter life. I chose this product after already owning another BlueAir purifier, because i was happy with the brand. This product is even better than my last one, and I recommend this especially if you have allergies,

If you are in need of a filter that has excellent auto detection, isn't too loud, and looks fairly good while sitting there? Here you go! Setup: to get the most out of this filter, you'll want to install the app. You can use it without it the app by using the buttons on the top of it, but to get the most out of it...get the app! The app is easy to set up. I already had another Blueair filter, so adding this one to my app was very easy. Following the instructions it only took a few minutes. Use: You can use this in manual mode, or automatic mode. In manual mode you set the fan speed and it just sits there and runs. In automatic mode, it senses particles in the air and adjusts fan speed as needed. This filter only senses one "type" of particle (which is basically smoke and actual small particles in the air). This overall works very well. There are some higher end filters that are able to detect multiple different types of particles, but they do cost much more. If you are using the app, you are able to see what the filter is sensing, and also change modes. You can also set schedules. This filter is in my bedroom, so I have it scheduled to go into "night" mode at, well, night. This turns off the LED's on the filter, and also sets the fan to its lowest speed. You are also able to buy different colors of "wraps" if you choose. They slip on and off the bottom (the gray part in the picture). Overall: This is a nice filter, and isn't too noisy even on its highest setting. I set it on auto mode during the day, and it seems to sense stuff very well. I burned some food cooking (which is on the floor below), and I went upstairs and it was on high working to clean the room. 30 or so minutes later, it was back down on low.

This is the air purifier you are looking for. Comes in a nice sized easy to unbox package. Comes as 1 unit that doesn't need to be assembled. Just take it out of the box, plug it in, and you are good to go. Comes with an instruction manual that I would recommend to read. You have to download the app to pair your phone using bluetooth which is very easy to do. The air unit itself is very light surprisingly so it's easy to carry and move around to different rooms if need be. All the buttons are on the top of the unit, making it easy to access and so that you don't have to bend down and strain yourself to see the buttons if they were on the front of the unit. This also has 3 speed settings, which are useful depending on the environment, and unlike my experience with other units, even on the 3rd speed which is considered "high", it still is not super over powering to the point of being annoying. You can run it on high during the night if you have it in your bedroom and would not be distracted by this. The app like I mentioned is great and easy to use. Very intuitive. You can turn it on/off from the app, or adjust the speed. From the app you have more than just the 3 standard speeds as well. You can do fine adjustments and do 1.5 or 2.5 if you like instead of full speed changes. You can also turn off the led light if that is distracting or enable the child lock. The app also gives you a status of the filters so you know when to change them. It also tells the quality of the air and if you were running it it will show you the time remaining until the air is cleaned. Very helpful and useful stuff. I have no issues with this and would recommend it to anyone.

We purchased this as we have 2 dogs and it's just inevitable that at some point the house has a dog smell (especially when they go out in the rain). That said, we just moved into a new home and in one of the spare rooms, there was a heavy paint/glue smell. We plugged this in, and it helped with the smell within a couple of hours. Great product.

Works great! Not too loud. I have noticed an improvement in my daughters allergies since using this.

Great air purifier, quiet and efficient. I love the application that shows when you need a new filter.

I just love this air purifier it keeps the air fresh

This air purifier has a modern attractive aesthetic but the performance is nothing special. Even though they call it "HEPAsilent" it seems just as noisy to me as any other air purifier I've had, so don't buy the marketing on that. To me the fan also seems a bit high pitched and shrill at higher speeds compared to other air purifiers I've had. At very low speeds it is quiet, but it's also barely moving any air so it's hard to count that. The app is a neat feature to have and seems to work great.

Easy to setup, runs very quiet. The automatic setting is ideal forour setting

Quiet and great at dust particle reduction thank you

We love the auto feature as it kicks on by itself when cooking odors are strong
