Details
Welcome to the next generation of air purification with Blue Signature – the most powerful, compact and customizable air purifier you can get. It features an advanced 7-stage filtration system that captures 99.97% of airborne pollutants, including dust, pollen, smoke, and pet dander. What sets it apart is its OdorFence Technology, with double the filter media and a patent-pending formulation that breaks down odor-causing gases at a molecular level—making it up to 10x more effective at removing stubborn smells. Despite its compact, minimalist design, Blue Signature delivers powerful, whole-room purification through Surround Boost Airflow, which uses 360° aero-optimized engineering for fast, even air distribution. Intelligent AirSense Technology allows the purifier to automatically sense and respond to your environment, adjusting airflow based on real-time readings of fine particles (PM1, 2.5, and 10). It even refreshes the air throughout the day, whether pollutants are detected or not. The sleek Scandinavian design blends beauty and function, with soft ambient lighting, customizable fabric pre-filters, and a side-table–friendly form factor. Blue Signature is quiet, easy to maintain with tool-free filter replacement, and compact enough to fit into any space—delivering a smarter, cleaner air experience without the bulk.
