Why Blueair is Healf

Blue Signature™ SP4i Large combines HEPASilent™ filtration with OdourFence™ Technology to remove both airborne pollutants and unwanted household odours. HEPASilent™ filtration captures at least 99.97% of airborne particles as small as 0.1 microns, including fine dust, pollen and other microscopic pollutants, while OdourFence™ Technology captures and breaks down common odour-causing gases rather than simply masking them. This advanced seven-stage filtration system helps you enjoy cleaner, fresher indoor air throughout larger living spaces.

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.
