“Better air helps me sleep, recover, and show up at my best–whether I'm stepping onto the court or spending time with my family. That's why I'm excited to partner with Blueair.”

Josh Hart, NBA NY Knicks Guard & Blueair Ambassador

“I tested it with kitchen odors 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.”

FAQ

What is the warranty for Blue Signature™?

How often do I need to change the filter?

Your filter will last up to 1 year thanks to our unique patent-pending design & proprietary RealTrack algorithm that accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.

When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you. Alternatively, connect to the Blueair app to receive an alert and easily re-order at the touch of a button.

Blue Signature™ Small Nordic Fog
Rated 5 out of 5 stars
Small but mighty!
I couldn’t be more happy with my Blue air purifiers. Noticeable improvement in my overall quality of life, breathing is not longer a struggle.
Most importantly my migraines have lessened.
Being able to utilize my Hsa/Fsa funds made this possible. Happy customer!
