3M Prefilter & Prefilter Holder for PF-600E/DF-600E

3M Prefilter SS-6600 can help extend the service life of 3M DT-Series filters (previously known as Pro2000 filters) by trapping large particles that may otherwise clog the filter. Frequently replace the prefilter to help maintain system performance.

Prefilters are maintenance-free and should be discarded when clogged or damaged. For safety and comfort, make it a habit to check and replace old or damaged parts as needed. The prefilter holder secures the prefilter in place on the filter.

Use with PF-600E/DF-600E. Pack contains 2 prefilter holders and 6 prefilters.
