This thing works wonders! My wife has a dog allergy and we just happened to get 2 new dogs for the boys for Christmas. For days, she was super congested and sneezing. Day 1 with the filter going and its like the dogs arent even there!

Seems to work well. I don't feel like l’m having as much allergies. Always reads excellent air quality

I’m beyond happy with my BlueAir Pure 511. The odor cleaning is incredible—whenever I cook, I keep it running in the kitchen and it clears everything right out. It even kicks on automatically after a hot shower, leaving the air fresh and clean. This purifier has also made a huge difference with allergies and dust; the air feels lighter and easier to breathe. I love it so much that I plan on buying a smaller one so I don’t have to keep moving this one around the house. If you’re looking for an air purifier that really works, this is it!

I highly recommend this if you are a clean freak or have allergies. It is actually pretty quiet on low and medium. Once you crank it up to high, then the sound is noticeable. So because of that you can just put it on high either at night for some nice white noise or when you leave the house. I noticed now when the sun shines through the window there is almost no dust floating around. I know the replacement filters are pretty expensive, but if you go to Amazon, you can get some filters from other manufacturers that are a lot less expensive.

Quiet, useful and keeps the air clean. We keep it in the bedroom

I've been using several Blue Air products in the past six years or so, but this one is the first with the smart feature. Scheduling through the app is easy and will help sustain the filter for more prolonged use. The new technology makes this even smaller in size, enough for our living room.

So far it works great. Love the added feature of night mode to be quiet and turns off the led light. I was confused about the sleeve and filter installation due to if having nothing but the fabric sleeve around the filter as most other have a housing unit. I don’t believe the indication light for clean air as we did put it in the basement with lots dust, known very high radon levels, and in general known to not be good air it still gave us an immediate green light. Not sure that it actually considers the air quality at all but it was a good idea to have just in case but not worth extra $ if it doesn’t work.

The product was easy to set up, and connect to the app. The app was simple to set up and automate. The 511i is user friendly and truly cleans the air. I would highly recommend.

Seems to be working great so far. I put the fan on 3 most of the time as on auto it normally says excellent air quality. The white noise is an added bonus

We are big fans of Blueair and have several in our home. We purchased this model for our daughter's bedroom. It is easy to use and we love that we can make changes from the app on our phone. The air feels purer when it is operating and there seems to be less dust on surfaces in the room. Our only issues: it can be a bit loud when running in its highest setting, it's price is higher than many competitors and the filters are expensive.

Works so well! My husband wakes with a stuffy nose every morning--until we got this purifier. Noticed a change the first day. Only thing I'd change is the size--you need a little plant stand for it.

It really is as quiet as advertised and seems to be working well - it did a good job cleaning the air in our kitchen after a smokey dinner. Connecting it to the iPhone through the app was pretty simply too.

And it's so quiet you need to check to make sure that it's turned on. Had it for a month now and it seems to make my room feel cleaner and I noticed less dust so obviously it's doing it's job

Setup was easy and results are fantastic. And it looks great too!

It really works and is easy to use with good design and app control functions. Also, it occupies little space and light weight so easy to locate anywhere.

Excellent product and does the job very well. When it's cleaning the room, the noise can be a little louder. I try to schedule it from the app to clean it at particular times and schedule a night mode when I'm sleeping so I don't get disturbed.

I like the quality of this decice, simple to use, cleaner air to breath

Good little purifier for apartment. Cool to see the AQI even when not home.

Really like this air cleaner. Very light & easy to move. Love the colored lights for air quality.

One night, I woke up coughing and my husband turned the air purifier and the coughing instantly went away. When we turned it on it showed that the air quality was not good, but it was nice to know that it works and it works great!
