BLUEAIR DustMagnet 5400 Series ComboFilter, Genuine Replacement Filter for DustMagnet 5440i, 5410i Home Air Purifiers for Dust, Virus, Bacteria, Smoke and Allergies

Dust Magnet 5400 Series Combo Filter is a genuine Blueair replacement filter compatible with Dust Magnet 5440i and 5410i air purifier models. Combo Filters are designed to ensure optimal removal - with one filter at the top and one filter at the bottom and data-based filter lifetime tracking, and longer filter life (maximum of 1 year). A dual air intake and vortex airflow pattern keeps airborne dust particles moving, and an electrostatic charge cluster them together. Once inside, dust particles stick to the charged stainless steel pre-filters, just like a magnet. Combo Filters include a particle filter to remove dust and other fine particles and integrate carbon to effectively trap VOCs, chemicals and light household odors from pets, cooking, smoking and more. Please check your local recycling facilities for availability. Unlike look-a-likes, authentic Blueair replacement filters are guaranteed to maintain optimal performance over time. Your Smart Filter will last a maximum of one year depending on room conditions. To ensure performance, replace your filter when alerted by the air purifier and/or app that replacement is needed. NO COMPARISON: Blueair models with HEPA Silent mechanical and electrostatic filtration produced higher CADR, lower noise, and had lower energy consumption vs. the same models with only mechanical filtration (H13 filter)."
