ACiQ 10 Inch Duct Inline Air Purification Filter Box with HEPA & Carbon Filter

The ACiQ AFH250 Air Purification Box is the largest model in the AFH series, designed for large residential and commercial indoor environments. Featuring a 3-stage filtration system, it helps improve indoor air quality in spaces requiring continuous, clean air circulation. Its HEPA filter captures fine airborne particles such as dust, smoke, and PM2.5, while the activated carbon filter helps reduce odors and formaldehyde. The 9-inch duct size allows easy integration into larger ducted ventilation systems, making it suitable for offices, workspaces, and open-plan interiors. Designed to operate in conjunction with an inline duct fan. The ACiQ AFH250 installs directly inline within a 10-inch round duct run to filter incoming or circulating air before it enters the space. With its robust metal housing and standard duct connections, the unit is easy to integrate into larger ventilation systems while providing enhanced air purification for spacious residential or commercial environments.
