CPF General Service Filters

Reduce your overall filtration costs with CPF's general service products utilized in simple to the most complex applications.

Our general service filters are produced using the same quality materials and manufacturing excellence as our other product lines, so you can be assured of their performance, dependability and scalability.

While general service filters are not integrity tested or validated for retention, these highly efficient filters remove large amounts of contaminants early in the process to reduce the load on your expensive downstream filters. They are also useful as stand-alone clarifying or particle removal filters in less
critical applications.
