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%² of tiny airborne pollutants down to 0.1 microns, such as fine particles, dust mite allergen, pollen, bacteria, virus and mold allergen⁴OdorFence captures common odor gases and breaks them down. It’s deep, effortless clean air you can feel, and smell, every day.

“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.”
