Blueair filters are key components for its air purifiers, designed to offer a fresh and healthy indoor environment. Their HEPASilent filters, a blend of electrostatic and mechanical filtration, capture 99.97% of airborne particles as small as 0.1 micron, like pollen, dust, and bacteria. Activated carbon filters, such as in the DualProtection series, excel at removing VOCs, odors, and harmful gases. For models like Blue Pure 211+, specific filters trap allergens efficiently. Replace filters every 6 – 12 months, depending on usage, to maintain optimal performance and ensure continuous clean air.
