Can-Filter Pre-Filters

A clean Can Pre-Filter will extend the working life of your CanFilter. Use to keep dirt, dust and contaminants from clogging the pores of the activated carbon.

Unique Features:
• Easy to use and change
• Very low air resistance
• Extends the life of your air filter
• Available in ALL sizes (from 33 to 150 — select from drop down menu)

Grower’s Tip:
PreFilters are used to block particles from getting into the pore structure of the carbon. To prevent a decrease in airflow — or an increase in pressure drop — they should be replaced when dirty.
