Doulton ceramic water filters are designed to convert raw water into highest quality drinking water that meets the most stringent potable water standards.
Due to rapid urbanization, chemical run off from industry, agriculture and private households is increasing.
Although it has seldom an immediate effect on the human organism it is very dangerous if ingested over an extended period of time. Most chemical contaminants can be reduces by the means of a carbon filter (GAC, compressed or extruded block form filters). Doulton water filter will remove 100% protozoa like amoebae, giardia and cryptosporidium. If ingested over an extended period of time it can be harmful to your health. Chlorine is used in many countries for the treatment of drinking water. It is a known fact that chlorine will react with organic matter in the water to form the cancer causing thihalomethanes (THM's). Just like iodine chlorine is not effective in killing protozoa. They will both decompose quickly and can not offer a long term protection. KDF filters are effective for chlorine reduction and are better than solid block carbon.
Doulton filtration technology is the most advanced in removal contaminants all 100% naturally.
