3M™ Prefilter and Prefilter Holder SS-6601

3M™ Prefilters for Powered Air Respirators can extend the service life of 3M™ Filters by trapping large particles that may otherwise clog the filter.

Help maximise the service life of your 3M™ Filters with 3M™ Prefiltes. Prefilters help prevent clogs by capturing large particles before they reach the filter. Frequently replacing the prefilter can help to 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.
