Customer Ratings & Reviews

It is very quiet and small enough to not take up a lot of space. It has helped with son's allergies immensely. I highly recommend.

Efficient product for a dorm room! Quiet, effective, clean air.

I love this air purifier. It is quiet, works so well and has made a big difference this allergy season in our house. And you can track the particulate matter via the app. I would highly recommend this product!

I recently adopted two kittens and because of that I didn't want to be prone to being nose blind and having my apartment smell like cats when I have people over. So I bought this to help remedy that especially since I have to keep their litter box in our living room. I'd like to say it's doing its job because it makes the entire living room really smell like nothing which is a good thing. I've even had people come over and they say it smells just normal in there. I guess the only tiny drawback is that one of my cats likes to scratch on it due to the fabric material on the outside but that really has nothing to do with the actual product and I've gotten him to stop. The app for it is really insightful and you're able to set schedules and control the fan speeds and even see an air quality indicator if you like tracking that sort of stuff. Even though it's on the smaller side, it definitely purifies the air in the entire living room plus a little bit into the kitchen. Another big plus is it's really quiet, especially on the auto mode. Overall, I recommend this for anyone with pets or even if you just want to breathe in better air, whether that be in small to medium living room or a bedroom.

I bought this for my husband and my son. My son suffers from allergies and my husband’s knows dries up with fan. The first day in use was a game changer. Both slept through the night and woke up charged and not sluggish. It is quiet, effective and has different options for smaller and larger Tommy. Will be purchasing for my daughters, my mother and our living room. You won’t regret this purchase

Excellent affordable price quite sound reasonable size efficient

Small foot print but packs a punch. Quiet too! Will be again as a gift.

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!

Works great. Pairs easily with the app and is quiet and stylish.

Does a great job is very quiet cleans the air fast

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.

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.

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.

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.

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

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.

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!

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.

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

this Blueair are purifier is extremely quiet snd compact. It is superior to my other purchases.
