7 stages of superior filtration and smart VOC sensing for 10x³ more odour 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 allergens, pollen, bacteria, virus and mould allergens.⁴

OdourFence captures common odour 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

How often do I need to change the filter?

You 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.

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!

Noticeably reduces dust in the bedroom and quiet
After a few weeks use, we learned that Aerosol deodorant pollutes the air quite dramatically. The filter did a great job in Auto mode - speeding up the fan until the air quality had returned to normal.
It is very quiet.
