This filter is made of highly compressed ceramic with diatomic substance. The surface of the dome consists of millions of pores that measure 0.2 microns in diameter, while most bacteria is 0.5 to 1.0 microns in size. The ceramic filter dome is secured inside the top tank. When contaminated water is poured in the filter, it will trap dirt, debris, contaminants and most bacteria before the water passes to the “clean” side of the filter to ensure that your water is free from any harmful diseases such as typhoid, cholera and dysentery. We encourage our customers to clean this filter at least once a month or as frequently as necessary, depending on the quality of your local municipal water. A layer of trapped dirt and gunk would accumulate on the surface, clogging the pores of the filter and slowing down the drainage of the water. Filter Life / Replacement: Micro-Ceramic Filter Dome: Replace every 1 year or 1,000 gallons, whichever comes first
