AC Infinity Duct Air Filter Box – Inline Intake Filtration

Filter the air on the way in, not just on the way out

Carbon filters clean what leaves the room. The AC Infinity Duct Air Filter Box cleans what comes in — a steel housing that takes a standard pleated MERV filter and sits inline on the intake, catching dust, pollen and spores before they reach the canopy or coat a heat exchanger.

The door is hinge-sealed with a slide lock and a neoprene gasket, so changing a filter takes seconds and nothing bypasses the media while it is running. Replacements are ordinary domestic sizes rather than a proprietary cartridge.

Key Benefits

• Traps 0.3 to 1.0 micron particles — FPR 10, MPR 1500–1900 pleated media
• Tool-free filter changes through a slide-lock door
• Neoprene seal so air cannot slip past the media
• 1mm cold-rolled steel body with a matte black powder coat
• Takes standard MERV replacements, not a proprietary cartridge

Which size do I need?

Match the box to the fan, not the room. Each size has a minimum airflow range as well as a maximum — run too little air through a large box and the media does not work as intended. The 4 and 6 inch take a 12 × 20 × 1 inch filter; the 8 and 10 inch take 14 × 20 × 1 inch.
