FAQ
- KHKristine H.Verified BuyerYesterdayReviewingBlue Signature™ Medium Nordic FogRated 5 out of 5 starsAmazing!
we have three cats and we replaced this system in our living room and it smells so much better. Love the air fresh sensor.
Highly recommend if you have pets
- KHKelly H.Verified BuyerYesterdayReviewingBlue Signature™ Large MidnightRated 5 out of 5 starsThird purchase Blueaire
I have 2 dogs and 3 cats and a very keen sense of smell. We purchased a Large a few months ago. Instantly I could tell the difference.
When an opportunity arose for a deal my wife opted for the 311i. I enjoyed the advanced features on the Large and let my wife know that we would buy another one when on sale. Hence our third. It is an excellent system and the changes are noticeable. I breath better and my house is a much more comfortable environment to live in.
- LDLatifah D.Verified BuyerYesterdayReviewingBlue Signature™ Large Nordic FogRated 5 out of 5 starsMy Blueair upgraded my environment
Everyday I look forward to challenging the personality of my air purifier. She rises to the occasion everyday as quietly powerful and effortlessly efficient. She’s an energy star powerhouse that works hard every day while she never fails to translate into low costs everyday. Within hours of cutting on my filter the air was fresher with an excellent reading. Everyday I cook it continues to clean the air restoring excellent air quality from smoke and odor. It was a surprise to me that within two weeks of bringing her into my home, I have been sleeping far better through the night,
Its modern design meshes well with my home decor. It performs with precision set apart from other manufactured models. Everyday it continues to deliver the same high level performance without demanding attention. I forget it’s here until I leave home and return to fresh air,
I love that she accomplished upgrading my environment’s air quality, my health, and my everyday comfort, Blueair isn’t just a purchase. My big blue is an investment in how I live.

- JLJohana L.Verified Buyer2 weeks agoReviewingBlue Signature™ Large MidnightRated 5 out of 5 starsReally works!
This is honestly the quietest air purifier I’ve ever had. It’s been so much better than other brands I’ve tried (including the big-name ones like Dys***). And the best part? It actually does what it’s supposed to do.
I live in an apartment, and every time we cooked, the smell and smoke used to spread everywhere. Since getting this purifier, that’s no longer a problem. We just leave it on Auto mode, and it jumps into action the moment we start cooking.
We’ve also realized there’s way less dust around the living room and bedrooms, which was a nice surprise. Overall, we’re really happy with it so far. I'm gonna buy another one exclusively for my baby's room since is very quiet.
