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.

Perfect
It has all the features that I wanted and does a fantastic job of eliminating odors, which is what I was hoping for. It increases speed as needed and I really like the added benefit of AirSense, which refreshes air twice a day. It looks great and doubles as a table. Very well executed.

Absolutely necessary
Love this purifier. I know it’s doing the lords work when I turn it off and smell things I otherwise got used to (sea grass rugs and a dog). I put it in a room that was freshly painted and the VOCs that had been lingering were eliminated within the day.
I like the size and look of the signature as well, especially with other color options for the cover. It makes it blend into the space and you can put something decorative on top if you want. Otherwise it looks great as is. Quiet too!
I’m not sure the auto feature will be for me; it says it detects clean air in spots where I just don’t agree. But perhaps it’s looking for pretty bad air from nearby smoke or something and not just small odors.

Love it!
There are lots of options, and great info in the app, but literally, turn it on, and let it do the work. Air is noticeably cleaner, amd most smells are squashed (I have it on top of the cat litter box)

Awesome product!
This is one of the best, smartest and quite air purification units I have ever had. It literally detects everything and purifies everything immediately. So quite that you could keep it right next to your bed. Add the wooden leg base and it makes a perfect bedside table/nightstand.
