Customer Ratings & Reviews

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!

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.

At first I was pretty skeptical of air purifiers but now we are FULL Blown believers in them. We mainly got it since our cats like to chew their arms, their vet suggested we get them an air purifier since they may be allergic to something in the environment. So we did, we had it in our bedroom, and it has for the most part helped with keeping them from eating their arm hair off. The app does let you know how polluted your air is, as well as there being a notification light on the device itself. I tested it on all levels of the home, and noticed that the room that only had a flow out vent, it kept the room cooler. But we still weren't completely sold on an air purifier, since the light near left the "great air" quality. So we decided to put it in the main room, which is the kitchen, dining, and living room. I decided to toast some bread in my convection oven, and for whatever reason, my convection oven malfunctioned and when the timer went off, the inside started to smoke. I hurried up and opened all the windows before the smoke alarms went off. This air purifier kicked on so fast, I would say it cleared out all the smoke, smell, and returned our air quality from heavily polluted to back to "great air" quality in about an hour. After that, we decided to keep it, and now are looking into another one for other parts of the house. Do I recommend this? Absolutely! Do you need the app portion? not really, but its cool to see where your air quality is, and see how much life you have on your filter.

So easy to use. Set up. Filter lasts so long! It is very quiet.

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

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.

It's not that small as expected and works well in my bedroom. Easy to setup as well.

So glad I bought this air purifier. It's so quiet that I cannot tell it's on, but it does it's job of purifying the air.

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

Set up was easy. The app works great. I can feel the change in air quality almost immediately.

Excellent affordable price quite sound reasonable size efficient

This smaller machine packes a punch when it comes to knocking out PM2.5s. I like that app and buttons are very easy to use - doesnt take a whole lot of intuition. I also like that the app will tell you how many minutes it will take to clean the space.

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

Love it! Living in an area with abundant trees. When in use this product is quiet and the air clean. Nice addition for my bedroom.

Easy to set up. Quiet. I keep it on auto and let it do its thing.

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

Quiet and efficient. It does the job and looks good.

Does a great job is very quiet cleans the air fast

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!
