Support & Manuals
FAQs
How often should I replace the carbon in this filter?
The lifespan of the carbon depends on usage, humidity, and the concentration of odors. For typical grow environments, we recommend refilling the carbon every 9 to 12 months to maintain optimal performance.
What's the benefit of a refillable filter over a standard one?
A refillable filter is more cost-effective and environmentally friendly. Instead of disposing of the entire steel and aluminum housing, you only replace the activated carbon. This significantly reduces waste and saves you money over time.
Is this filter compatible with other brands of inline fans?
Yes, this filter has a standard 4-inch flange and is compatible with any 4-inch inline duct fan. For best results and smart control, we recommend pairing it with a fan from the AC Infinity ecosystem, such as the Cloudline T4.
How do I know when it's time to refill the carbon?
You'll know it's time for a refill when you begin to notice odors escaping your ventilation system. A gradual decrease in odor-neutralizing effectiveness is the primary indicator that the carbon has reached its saturation point.
How do I set up my ventilation for the best results?
For optimal odor control, the carbon filter should be placed at the highest point inside your grow tent, as the first component in your exhaust system. Air should be pulled through the filter, into the fan, and then out through the ducting. For a complete walkthrough, check out our in-depth guide on AC Infinity ventilation kits.
