Compact Form, Big-Time Power
Despite its minimalist look, this little machine is a powerhouse. Blue Signature can purify up to 3,390 square feet in just one hour — that’s your open-concept kitchen, living room, and then some. Thanks to Blueair’s signature HEPASilent filtration, it catches 99.97% of airborne pollutants, from the obvious (dust, pollen, mould) to the microscopic (viruses, bacteria).
The kicker? It’s whisper-quiet and 40% smaller than comparable models. Power, without the bulk or the noise.
Smarter Than Your Average Purifier
Blue Signature doesn’t just react — it thinks ahead. With AirSense Mode, it keeps the air moving and refreshing even when the sensors don’t detect immediate pollution. Meanwhile, Auto Mode adjusts fan speed based on real-time air quality, and Night Mode dials everything down for restful evenings, dimming the lights and reducing noise.
Everything can be controlled with the newly enhanced Blueair app, which lets you tweak settings, schedule cleanups, and monitor filter usage with RealTrack. It’s smart-home-ready without the overcomplication.
Odour Control That Actually Works
Forget masking smells. The new Active OdorFence tech goes beyond typical filters, breaking down gas-based pollutants and tackling odour-causing particles at the molecular level. Blueair says it’s 10 times more effective at odour removal compared to similar products. Cooking smells, pet funk, mystery funk? Gone.
Design That’s Not an Afterthought
If you’re tired of hiding bulky purifiers behind furniture, Blue Signature is for you. This one was designed to be seen — or not, depending on your vibe.
Available in Midnight and Nordic Fog, with optional fabric pre-filters, wooden table legs, or a modern metal disc top, it’s got that Scandinavian “it just fits” energy. Bonus: the purifier’s top doubles as a side table, because why not?
Live Where You Breathe
We spend a staggering 1,600 hours a year in our living rooms — and it turns out, it’s one of the most polluted places in the house. Between cooking, cleaning sprays, open windows, and indoor allergens, we’re soaking up more than we realize.
Blue Signature was designed for real life. For the place where you hang out, work, stretch, snack, and sleep. It doesn’t just clean — it quietly, efficiently improves the air you live in.

You can pick up Blue Signature starting at $449.99 from Blueair.com or Amazon. Whether you want it to disappear into the room or show off a bit, it’s the most beautiful way yet to breathe easier at home.
