Filter Replacement Frequency

In most environments, filters are changed every 30-60 days depending on the severity of the environment. Monitor the airflow for the first 60 days and when you feel a restriction of airflow, it is time to change the filter. You can’t determine the frequency of change visually. Dust Free PC filter media is designed to hold twice the amount of contaminants over ordinary filters.

Turn Off Enclosure When Changing Filters

Always turn off the fans when changing the filter. Stopping the powerful fans will prevent pulling the dirt off the filter into the enclosure.
