AC Infinity Air Filter Box – Intake Dust Filter for Inline Fans, 4" to 10"

AC Infinity Air Filter Box – Clean Air In Is Half the Job

Everyone worries about what leaves a grow room; very few think about what comes in. An intake fan pulling straight from a loft, garage or garden brings dust, pollen, spores and the occasional insect with it, delivered directly onto your plants. A filter box on the intake stops that at the door.

• 1mm cold-rolled steel box with aluminium duct flanges, built to last
• Slide-lock door for quick filter changes, with a neoprene seal to keep it dust-tight
• Includes a high-efficacy filter that traps dust, dirt, lint and odour
• Accepts standard 12 × 20 × 1in replacement filters

Also used for home ventilation, workshops and loft extraction where dust is the problem.

🌿 Rose's Pro-Tip: fit the filter box on the intake side and check the filter monthly. A clogged intake filter quietly starves your fans and makes the tent run hot.

Pairs well with: Cloudline EC inline fans, four-layer ducting, grow tent duct vents.

FAQs

Where does it go?
On the intake side, so fresh air is filtered before it reaches your plants.

What replacement filters does it take?
Standard 12 × 20 × 1in filters, widely available.

Will it slow my fan?
A clean filter has little effect. Check it monthly and replace it when it's visibly grey.
