7 stages of superior filtration and smart VOC sensing for 10x³ more odor removal

Smart VOC sensing continuously detects airborne gases and chemical pollutants in real time. HEPASilent filtration technology captures at least 99.97% of tiny airborne pollutants down to 0.1 microns, such as fine particles, dust mite allergen, pollen, bacteria, virus and mold allergen⁴

OdorFence captures common odor gases and breaks them down. It’s deep, effortless clean air you can feel, and smell, every day.

“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
An improved control panel
We got this Small Nordic Fog unit for a bedroom, and it seems to be working just fine. I was a bit surprised when the controls lit up every time I (or our dog) neared the unit, unlike the 311i unit we have in our great room.

Awesome Purifier
Of all the air purifiers I have tried Blueair is the very BEST. They operate exactly as described, super quite, except when they detect pollutants and then go into overdrive, which is exactly the way it should be. The automatic mode is perfect, set it and forget it. I have 3 Blue Signatures small, medium and large. I have definetly noticed the difference in the house since having them. Easy to setup and pair with my Wi-Fi.

Blue Signature™ Medium Nordic Fog
Rated 5 out of 5 stars
What an Amazing Product!
I purchased the BlueairSignature several weeks ago and have been astonished at its sensing capabilities and air cleaning properties. This evening I was startled when--for seemingly no reason--it started operating at a high fan speed with the red light indicator on. My husband had been practicing golf swings on our foyer rug, repeatedly striking the rug. I wondered if by some chance it was related to the Blueair activity and Googled it. I was amazed to learn that it was directly related and was causing the release of toxic POCs as the club repeatedly struck the rug! At least I know the cause and solution, but this air cleaner is a life saver.
