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 allergen⁴ OdorFence 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.”

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.

What are the noise levels?

Blue Signature™ Small operates quieter than a whisper on low at 19 db and is no louder than 50 dB on high fan speed.

What room size is best?

To achieve maximum performance we recommend placing your unit in a room around 250 ft² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes. The Blue Signature™ will clean up to 1,200 ft² in 1 hour.

Efficient and Effective
We bought the Blue Signature air purifier to help us with our indoor air during the summer when we were experiencing significant wildfire smoke. The product arrived promptly and got to work on our poor air quality. Very happy with this product.
