3M™ Prefilter TR-3600, for Versaflo™ TR-300 PAPR 100 EA/Case

When installed inside the filter cover of a TR-300 PAPR, the TR-3600 prefilter can extend the life of the HE filter by capturing large particles that would otherwise clog the HE 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.
