Blueair uses a four-layer filtration system with HEPASilent™ technology that combines electrostatic and mechanical filtration to remove 99.97 per cent of airborne pollutants such as pollen, dust, and smoke. This approach captures tiny particles faster and more quietly than traditional HEPA systems, and it builds on technology first developed by the brand’s founder and now trusted in over 60 countries. All Blueair air purifiers meet CARB standards and operate within strict ozone limits, with independent testing at Intertek confirming emissions far below required thresholds. Several models also hold Zero Ozone Verification, which confirms ozone levels of 5 parts per billion or less. This proven, carefully tested system helps you breathe cleaner air with confidence every day.

Blueair was founded in 1996 in Stockholm by Bengt Rittri, driven by a simple goal: to ensure his children could breathe the same clean air indoors as they did in the Swedish archipelago. With a deep commitment to environmental responsibility, Rittri built Blueair into a global brand focused on healthier indoor living. The brand develops high-performance air purifiers using precision-engineered filtration technologies designed to capture airborne particles, allergens, and pollutants efficiently and reliably. Each system reflects a science-led approach, combining smart design with carefully tested components to deliver consistent air quality. Through this commitment to clean, effective solutions, Blueair helps create healthier homes so you can breathe easier every day.
