Who This Is For
- You are adding a filter box because dust and pests keep bypassing your intake fans and fouling your environment.
- You are installing this unit because you need to clean your intake air without choking your high-volume 8-inch fan.
What We Found
- The sliding door is much better than the thumb screws on cheap boxes that usually strip or get lost in the dark.
- We noticed the MERV 13 filter is thick enough to catch fine dust without significantly choking the fan CFM.
What Users Say
- Users who added this to their intake say they spend far less time scrubbing grime off their glass cooled reflectors.
- Operators who switched to these boxes say they stopped finding insect damage near the main air entry points.

FAQs
The box is designed to accept any standard 14 x 20 x 1-inch filter. It comes with a high-efficacy filter included, but you can replace it with any compatible MERV-rated filter based on your specific filtration needs.
Installation is straightforward. The 8-inch flanges are designed for a snug fit with standard ducting. It integrates perfectly with AC Infinity's ecosystem, especially the Cloudline S8 and T8 inline fans, ensuring a secure and leak-proof connection.
Yes, absolutely. You can install it on the intake side of your fan to prevent dust, pollen, and pests from entering your space, or on the exhaust side to trap particles before they exit. For odor control, it should be paired with one of our dedicated carbon filters.
Filter life depends entirely on the environment. In a dusty area, you may need to replace it every 1-2 months. In a cleaner environment, it could last 3-6 months. We recommend checking the filter monthly and replacing it when it appears visibly dirty to maintain optimal airflow.
