Active Air Pre-Filter for ACCF398, 8" x 39"

The Active Air Pre-Filter for ACCF398 is an 8 x 39 in replacement pre-filter for indoor grow carbon filters. It slips over the filter body and traps dust, dirt, and lint before they reach the activated carbon. It's the most economical way to keep your odor control working at its best.

Benefits

• 8 x 39 in size, specifically designed for the Active Air ACCF398 950 CFM filter.
• Blocks large particles that clog the active carbon surface.
• Extends the life of the carbon filter and maintains its extraction efficiency.
• Replacing the pre-filter costs much less than replacing the entire filter.
• Installs and removes without disassembling the duct system.

How to use

Turn off the fan, remove the used pre-filter, and slide on the new one until it covers the entire filter body. Smooth it out evenly, without creases that obstruct airflow, and restart the system. Check it every few weeks and replace it when it looks dirty or discolored.

Available at Pachamama with shipping throughout Costa Rica.
