As modern homes evolve towards spacious, open-plan designs, blurring
the boundaries between kitchen, living, and dining areas, our approach to air
quality also needs to evolve. To meet this challenge, Blueair have introduced the
Blue Signature™ air purifier, which delivers extraordinary purification power
in a remarkably compact form. As well as delivering remarkable purification,
the Swedish-designed Blue Signature™ complements contemporary living spaces.
Today's homes are bigger and bolder. Knock-through living areas, vaulted ceilings and expansive loft conversions have transformed how we inhabit our spaces. But whilst these airy, light-filled environments feel wonderful, they present a unique challenge: how do you effectively purify the air in rooms that seem to stretch endlessly?
The Blue Signature™ has been engineered to answer this question with confidence. This purification powerhouse rapidly cleans an impressive 65 square metres in just 12.5 minutes, and spaces up to 314 square metres within an hour. Whether you've got a sprawling open-plan kitchen-diner or a generously proportioned sitting room, the Signature delivers comprehensive coverage without compromising on performance.
What sets the Blue Signature™ apart is its sophisticated seven-stage filtration system, which removes 99.97% of airborne particles. This isn't simply about capturing dust. The advanced OdourFence Technology provides ten times more odour removal compared to previous models, making it particularly effective in homes where cooking aromas, pet odours or everyday household smells can linger in those expansive spaces.
The intelligent filter design is equally impressive. Thanks to patent-pending technology, filters last twice as long as conventional alternatives, reducing both maintenance requirements and long-term running costs. Each unit comes complete with one pre-filter and one Particle & Carbon filter, so you're ready to experience cleaner air from day one.
Modern homes deserve intelligent solutions. The Blue Signature™ features a dynamic display that automatically adjusts to enhance your air quality, whilst integrated air sensors continuously monitor your environment. Through the highly-rated Blueair app, you can control your purifier remotely, schedule cleaning sessions, and track filter life with ease.
The device offers six speed settings, including Auto and Night modes, ensuring optimal performance whether you're entertaining guests or seeking peaceful sleep. On its lowest setting, the Signature operates at a whisper-quiet 23 decibels, whilst its maximum 55 decibel output ensures rapid purification when needed.
We're delighted to announce the launch of our newest colour option: Nordic Fog. This sophisticated shade embodies the essence of Scandinavian design philosophy, bringing a touch of understated elegance that seamlessly integrates into any interior scheme. The soft, misty tone complements everything from minimalist white spaces to warmer, textured environments.
The cylindrical design, measuring just 39.4 cm in diameter and 43.7 cm tall, means the Signature occupies minimal floor space despite its powerful capabilities. The fabric exterior of the washable pre-filter adds a tactile quality that elevates it beyond a typical appliance, whilst ensuring easy maintenance.
As a Certified B Corporation, Blueair meets rigorous standards of social and environmental responsibility. When you choose the Blue Signature™, you're supporting a company that prioritises sustainability and ethical business practices alongside exceptional product quality.
Consumer testing confirms the real-world impact: 95% of users felt the Signature contributed to a healthier living environment, whilst 89% prefer it over any other air purifier they've tried. With 112 customer reviews averaging 4.8 stars, the feedback speaks volumes about performance, reliability, and satisfaction.
Whether you're navigating the challenges of open-plan living, managing allergies, accommodating pets, or simply wanting to breathe cleaner air, the Blue Signature™ delivers uncompromising performance wrapped in beautiful design.
