It is a good idea to replace the pre-filter Can-Lite 300 when they become dirty. A dirty pre-filter increases the pressure drop, which will decrease the air flow through the filter. A clean pre-fi filter will also extend the life of your filter and cause it to be more effective.
Very low air resistance, easy to replace, prevents dust, pollen and other contaminants from entering the filter. A clean Can-Filter pre-filter is a great way to extend the life of your Can-Filter.
Maintain optimal airflow and the life of your Can-Filter with a clean pre-filter. Simply remove the existing outer pre filter and replace.
