Katadyn Combi Ceramic Replacement Cartridge

The ceramic filter can handle down to 0.2 microns, which means that it is effective against microorganisms. The function can be compared to a mosquito net in a window, the mosquitoes are too big to pass through the fine mesh net. Same thing with the dirt (bacteria, giardia and cryptosporidium) in the water, it doesn't pass through the ceramic filter, only the water does.

99.999% of all bacteria, 99.999% of all parasites, microplastics and reduces chemicals. Carbon filters also remove viruses
