The KKOIUGQK 10‑inch inline filter box delivers superior air purification through a sophisticated three‑layer system. A pre‑filter captures larger particles, a high‑efficiency HEPA media removes 99% of PM2.5 particles, and an activated carbon layer infused with silver‑ion photocatalyst neutralizes odors, formaldehyde, and other industrial gases. Housed in a durable galvanized steel enclosure with a corrosion‑resistant finish, the unit is built to withstand the rigors of demanding ventilation environments such as HVAC systems, grow rooms, basements, garages, and workshops.
Designed for seamless integration, the compact 4‑inch deep box measures 17.5″ × 11.8″ × 11.8″ and fits standard 10‑inch inline ductwork. It supports airflow rates between 59 and 147 CFM, with an initial pressure drop of 100‑120 Pa, ensuring efficient operation without overloading fans. Installation is straightforward thanks to included mounting brackets that allow ceiling, wall, or freestanding placement. For optimal performance, replace the filter every 3‑6 months under normal conditions, or monthly in harsh weather environments.
