Katadyn Combi Replacement Element
Here's what other sites are saying:
Katadyn's Combi ceramic replacement filter removes bacteria and protozoans, including giardia and cryptosporidia.
Should you crack or wear out the ceramic element in your Combi water filter, reach for this replacement element so you can get back to sipping on high-quality H20. Slide this filter into the pump housing where you old filter sat and you're back in business in no time. Should a particularly dirty water source start to slow down your output, just pop this ceramic element out, give it a quick scrub with a sponge, pop it back in, and watch the water flow.
