RapidPure Replacement Filter Cartridge
The Rapid Pure Replacement Filter Cartridge will fit both the Rapid Pure Intrepid water bottle and the Rapid Pure Straw.
All water filters have a limited capacity and it is a good idea to have a replacement cartridge for your water filters around.
The Rapid Pure 2.5 inch replacement cartridge is the exact replacement for both the Rapid Pure Straw and the Intrepid water bottle.
