Remington Ceramic Water Filter OBE L(67mm) 2 in 1 Carbopure - Ceramic with Carbon Block Remington Ceramic Water Filter OBE L (3" x 9.75"/9") 2 in 1 Carbopure. Ceramic filters are no novelty in the water filtration industry, they have a long-standing history of being used as a filter media thanks to their effectiveness in removing bacteria, turbidity, viruses, protozoa, cysts, and other contaminants. How Carbopure works; 1. Tap water under pressure, flows from outside toward the inside of the sub-micron ceramic element. 2. Impurities unable to penetrate through the microscopic channels of the ceramic matrix, such as bacteria, Cryptosporidium and other micro organisms, are simply trapped on or near the surface of the element. Activated extruded carbon block inside ceramic shell. Bacteria-free water enters through the core of the highly activated extruded carbon block - another natural component of Remington ceramic element, which is used to reduce chlorine, pesticides, herbicides, toxic chemicals, as well as taste and odors which may be present in your water. The Carbopure element is capable of producing approximately 1,000 gallons (4,000 liters) of the highest quality drinking water - good for about nine months to a year for most families. Actual usage depends on the amounts and kinds of impurities in tap water. Cartridge replacement is as simple as changing a light bulb. Halal Certified by Jakim Malaysia
