Who This Is For
- You are adding a filtration box because dust and spores are settling on your harvest and compromising crop quality.
- You are integrating a dedicated intake because taped-on filters create air leaks and reduce your fan efficiency.
What We Found
- The sliding door seals tight without rattling, which is usually the weak point on cheaper intake boxes.
- We recommend these for intake lines to keep fan motors clean, adding years to the life of your ventilation gear.
What Users Say
- Users tell us their inline fans stay factory clean for months because this box traps debris before it hits the motor.
- Buyers say they stopped finding dust spots on their harvest after adding this to their incoming air supply.

FAQs
What is the main purpose of this air filter box?
It's designed to be installed in your ventilation line to filter incoming or outgoing air. It effectively removes dust, pollen, pet dander, and other airborne particles to maintain a clean environment for your plants.
What size ducting is this compatible with?
This model is specifically designed for 4-inch ducting and pairs perfectly with 4-inch inline fan systems like the AC Infinity Cloudline T4.
How often should I replace the filter?
Filter life depends on the air quality and usage. For typical grow environments, we recommend checking the filter every 1-2 months and replacing it every 3-6 months or when you notice a significant drop in airflow.
Can I use any brand of filter?
Yes, the box is designed to accept any standard 12" x 20" x 1" filter, including various MERV-rated options, giving you complete flexibility.
Does this filter box reduce fan noise?
While its primary function is filtration, the insulated steel construction can help slightly dampen noise. For significant noise reduction, we recommend pairing it with an AC Infinity Duct Silencer.
