Blueair Signature Blue 4.0 Replacement Filter Large, HEPA Filter Particle + Carbon + OdorFence, Genuine Replacement for Blue 4.0 Series, Removes 99.97% of Airborne Particles, 6-12 months usage

The Blue 4.0 Signature Replacement Filter is our most advanced HEPA filtration system yet. Powered by OdorFence molecular neutralization technology, it outperforms traditional carbon filters in eliminating stubborn odors. Combining HEPASilent technology with OdorFence™, this filter features a 7-stage purification process integrated into three high-performance layers: a fabric pre-filter, a multi-layer filter media, and an enhanced carbon filter. What sets this filter apart is its intelligent use of specialized elements: * Bio Enzymes, invisible to the eye, are embedded in molecular sieves to effectively neutralize pet odors like ammonia. * Molecular Sieves (yellowish particles) target and absorb scents from perfumes and cleaning agents. * Permanganate beads (reddish-purple) tackle harsh odors such as those from cigarette smoke and bathroom environments. * Activated Carbon Pellets (black, cylindrical) capture a wide range of chemical odors, including those from cooking and household fumes—engineered in pellet form to maximize surface area and absorption capacity. Together, these elements make the Blue 4.0 filter a powerful solution for cleaner, fresher indoor air.
