Hello Mike,

This is simple example as of how the CP100 works. You simply remove your faucet aerator (end of the spout), attach the filter diverter and you are done. Two adapters are included if our diverter does not match your spout thread. If you are not using the filter over the winter time make sure you remove and dry the ceramic candle for at least 24 hours. Also if the filter is not used for a period of 3 days and longer we recommend that you run the filter for about a minute, eliminating the stale taste of stagnant water.

This data, from tests conducted by independent laboratories, demonstrates the removal capabilities of Doulton's purification element. This does not imply that these contaminants are present in individual water supplies. Detailed test results available on request.

It should be clearly understood that the concentration of bacteria fed to the filtration element is artificially high in order to simulate a challenging test for the ceramic element. The most aggressive "real life" condition would normally be at least 1000 times less severe.
