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.”

Jake

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
Blue Signature small
This unit works great for my bedroom. It replaces a Blue Air 311+ auto that stopped running after about 3 years. This new unit has several technological improvements. It is quiet and small so I don’t notice it’s in the room.
