AC Infinity’s Duct Air Filter Box 10" with High Efficacy Filter is an inline intake filtration housing for 10-inch duct systems and CLOUDLINE fans. Built from 1 mm cold-rolled steel with aluminum flanges, it features a slide-lock, neoprene-sealed door for quick filter swaps. The unit ships with a pleated high-efficacy filter and accepts standard 14 × 20 × 1 inch MERV replacements. Designed for fresh-air intake, it blocks dust, lint, and odors before they enter grow rooms or HVAC spaces. The 10-inch collars provide a 9.72-inch (24.7 cm) internal opening. Overall size is 22.51 × 11.57 × 13.93 inches, and maximum supported airflow is 2400 CFM (about 4080 m³/h) when paired with high-static inline fans.
