Aqua Pure Filters

The 3M™ Aqua-Pure™ C-Cyst-FF filter is the recommended replacement filter for the discontinued Model A1 RV/Marine replacement filter. The C-Cyst-FF produces the clean, clear, and delicious water you want while traveling.

The C-Cyst-FF is for use with 3M RV/Marine Filtration Systems: US-A1 and US-B1. The 5610429 replacement filter cartridge is used to replace the Winnebago Class C OEM filter.

Note: The C-Cyst-FF is 2" longer than the the original Model A1 filters and may not be suitable for all installations. If you need the shorter style order the C-CS-FF filter.
