Introducing the Blue Signature™ Medium: The Best Air Purifier for Medium Rooms
-
Most of us don’t think about the air inside our homes. But it can be up to 5 times more polluted than the outside air.
From dust, pollen, mould spores, cooking fumes and VOCs from cleaning products, the air in a typical home carries far more pollution than most people realise, and it changes with every season. The Blue Signature™ Medium is the perfect solution to this: a best-in-class air purifier for medium rooms, delivering over 20% more pollen-removal power than a leading competitor at similar performance levels.1

Feel the Difference From the First Day
The Signature Medium can clear a 46 m² room in just 12.5 minutes or a 112 m² room in 30 minutes, which means fresher air in a living room or an open-plan kitchen-diner incredibly quickly. In a typical bedroom, it can clear airborne allergens in around 4 minutes.
For anyone who wakes up with a stuffy nose, itchy eyes or that vague sense of not having slept well, that matters. Clean air means better sleep and better sleep means better everything else.

No More Lingering Smells
A major benefit of the Signature Medium may is its powerful odour removal, smells that you become accustomed to and only notice when you re-enter the house such as lingering cooking smells. Even if you don’t notice it every day, you’ll appreciate the absence of the faint mustiness that creeps in on damp autumn days or the heavy background haze from candles and wood fires in winter.
This is achieved using the Signature Medium’s OdorFence Technology, which breaks down common odour gases. When combined with HEPASilent filtration that captures 99.97% of airborne particles down to 0.1 microns, the air in your home simply feels cleaner, fresher and easier to breathe.

Year-Round Relief, Not Just a Spring Fix
Air purifiers are not just a seasonal purchase, the Signature Medium earns its place in your home all year long.
In spring and summer, it tackles pollen drifting in through doors, windows and on clothing, providing real relief for hay fever sufferers at home when they need a break from outdoor exposure. During autumn, it captures mould spores that thrive in damp conditions, along with smoke from candles and open fires. Come winter, when windows stay shut and central heating dries the air, it keeps dust mite allergens and VOCs in check and helps your home feel less stuffy when the windows stay closed.
Blue Signature Medium is an investment in comfort for every month, not just a few.

Designed to Live in Your Home, Not Hide in It
Most air purifiers ask you to make a compromise: accept something large and utilitarian in exchange for the air quality benefits. The Signature Medium doesn’t.
At 49 cm tall with a 30 cm × 30 cm footprint, it’s genuinely compact. The top doubles as a surface, so it fits naturally on a sideboard, beside a sofa or in the corner of a bedroom without demanding attention. A motion-activated touchscreen wakes when you approach and sleeps when you don’t, keeping the look clean and considered.
Choose Nordic Fog for a calm, Scandinavian aesthetic that disappears into light, airy spaces. Choose Midnight for a bold purifier that makes a statement rather than hiding from one. Both come with interchangeable pre-filter covers so you can personalise the look to suit your room.
“The Blueair Blue Signature finally gives design-conscious homeowners an air purifier they won’t want to hide.” - Yanko Design

Set It and Forget It
Despite its impressive design, the Signature Medium is built to run in the background of your life, not demand constant attention. Connect it to the Blueair app and it handles itself: Auto mode monitors air quality in real time and adjusts fan speed accordingly, so you get clean air without ever touching a setting.
When you do want control, it’s all there. Set schedules around your routine. Check filter life at a glance, with a reminder when it’s time for a replacement (every 9 to 12 months). Use Night mode for whisper-quiet operation at just 23 dB, which is barely audible in a silent room.
For families, the display can be locked to prevent little hands from changing settings. For light sleepers, it’s a near-silent companion from dusk to dawn.
