AC Infinity Activated Carbon Refill

The IAV (Iodine Adsorption Value) rating measures the charcoal's ability to adsorb impurities. A 1200+ rating indicates high-grade, porous carbon that is exceptionally effective at trapping volatile organic compounds and stubborn odors common in indoor gardens.

While this refill is designed for AC Infinity filter casings, it can technically be used with other brands if the filter housing is accessible and allows for manual refilling. Ensure your existing filter is designed to be opened and repacked before purchasing.

This package is designed to refill a 4-inch filter approximately four times, a 6-inch filter twice, or an 8-inch filter at least once. The exact number of refills may vary slightly depending on how tightly you pack the charcoal granules.

No, this activated carbon is not washable. Once the charcoal has reached its adsorption capacity and is no longer effectively removing odors, it must be replaced with fresh granules.

You should replace the charcoal when you notice a decrease in odor control or a persistent smell in your grow space. Depending on the humidity levels and the intensity of your plants, most growers find they need to refresh the carbon every 6 to 12 months.
