Active Air Pre-Filter for ACCF144, 4" x 14"

The Active Air Pre-Filter for ACCF144 is a 4 x 14 in replacement pre-filter for indoor grow carbon filters. It is placed as a sleeve over the filter body and retains dust, dirt, and lint before they reach the activated carbon. It is the most economical way to keep odor control working at its best.

Benefits

• 4 x 14 inch size, designed specifically for the Active Air ACCF144 215 CFM filter.
• Blocks large particles that clog the active surface of the carbon.
• Extends the life of the carbon filter and maintains its extraction efficiency.
• Changing 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 exhaust fan, remove the used pre-filter, and slide on the new one until it covers the entire filter body. Arrange it evenly, without creases that obstruct airflow, and turn the system back on. Check it every few weeks and replace it when it looks dirty or discolored.

Available at Pachamama with shipping throughout Costa Rica.
