“I tested it with kitchen odours while cooking, and within about 20 minutes of running the air purifier, I could smell little to nothing. I find that astonishing. I've used other air purifiers before, but this one does the trick.”

- KLKrzysztof L.Verified Buyer3 minutes agoReviewingBlue Signature™ Small MidnightRated 5 out of 5 starsVery good
It is small , neat, and runs quietly. Even for a small room (20m) I recommend buying at least a medium sized one. I am very satisfied
- DLDavid L.Verified Buyer11 hours agoReviewingBlue Signature™ Small Nordic FogRated 5 out of 5 starsDealing with seaplane fuel stench. Solved
We live near a place where seaplanes take off. The aviation fuel smell is horrible. Had good success with Blueair products before, so bought a medium for the living room. Amazed how well it did. To the point of walking outside and smelling exhaust, but not smelling it inside. Bought another for the bedroom.
- MCMatthew c. S.Verified BuyerYesterdayReviewingBlue Signature™ Medium Nordic FogRated 5 out of 5 starsGame changer !
I moved into my new room just a few years ago and it has become progressively more and dustier months by month . So much so that my health was beginning to suffer . Even vacuuming had only a partial effect . I knew that air purifiers were available and as my cough was becoming worse and worse I decided that was the course of action . I'm very glad I did the air in my room is fresh it seems to tackle the dust at a significant level . I breathe much more deeply and like fresh air and my cough has improved so .that it's almost gone ..

This product is amazing for my bedroom.Every morning I used to start sneezing as soon as I woke.
After using this product I can honestly say I have stopped sneezing and my breathing is much better.
Also the dust level has dropped considerably.

We bought this as we have two wood burning stoves and had some worries about particles from them. In reality neither stove cause a problem, but after two weeks of running the Blue Signature it was covered in dust which made me think that it really is doing something. It’s mostly unobtrusive, but when it’s on full power it’s a bit intrusive if you are next to it. I’m impressed that it really is doing something to our air quality.
