Features: Filter precision can reach 0.2-0.5 micrometre; under 3kg water pressure, the output is 180kg/h. Lightweight with high pore ratio and density less than 0.8g/cm; pore ratio is 1.3-1.5 times that of a standard ceramic filter. Under the same conditions, its permeability is 1.5-3 times that of a standard ceramic filter element. Pores are evenly distributed with high filtration precision down to 0.1 micrometre. Self-cleaning capability is effective without self-contamination. Easily regenerated by rinsing with a brush, light sanding with sandpaper, or flushing with clean water for repeated use. Removes harmful bacteria such as E. coli, fecal coliform, Salmonella, Streptococcus, and cysts (Cryptosporidium, Giardia). Reduces unpleasant taste and odor, sediment, and asbestos. Cartridge can be washed up to 30 times. Flow rate of the ceramic filter can be restored by gently brushing the outer surface with a stiff toothbrush, plastic brush, or soft scouring pad under running water. As the top layer of ceramic and trapped contaminants are removed, a fresh filtering layer is exposed. Main ingredients: Kieselguhr and inorganic antibacterial agent. Note: Do not use soap, detergents, or steel wool.
