ACiQ 4 Inch Duct Inline Air Purification Filter Box with HEPA & Carbon Filter

The ACiQ AFH100 Air Purification Box is a compact, high-efficiency air filtration solution designed to improve indoor air quality in small residential and light commercial spaces. Engineered with a 3-stage filtration system, it effectively captures airborne contaminants while eliminating odors and harmful gases. This unit features a pre-filter that traps large particles such as dust, mold, and spores, followed by a high-quality activated carbon filter that absorbs odors and formaldehyde. The final stage is a high-density HEPA filter, capable of removing fine particles including smoke and PM2.5 for cleaner, healthier air. With its 4-inch duct connection and compact housing, the AFH100 is easy to integrate into ventilation systems, making it ideal for new homes, baby rooms, and small offices. Designed to operate in conjunction with an inline duct fan. The ACiQ AFH-100 installs directly inline within a 4-inch round duct run to filter incoming or circulating air before it enters the space. With its compact metal housing and standard duct connections, the unit is easy to integrate into existing ventilation systems.
