Katadyn Vario Replacement Ceramic Prefilter Disc

Keep your Katadyn Vario Microfilter in tip-top shape with the replacement ceramic prefilter disc. Ceramic prefilter disc blocks larger particles before they reach the pleated filter cartridge; disc is field cleanable when pumping becomes difficult. Replace the prefilter disc when the ceramic is visibly worn-off to the point where plastic is showing through.
