Safety, Non-toxic, Recycling Filter Ceramic water filters work by simply allowing the water to seep through tens of millions of pores in the water cartridge surface. In the process, organic and inorganic particulates too large to pass through (often anything larger than 0.5 micron) accumulate on the ceramic surface. As a point of reference, even cysts (like Cryptosporidium and Giardia) are too big in size to squeeze through the tiny pores of the ceramic filter cartridge.
