Quality of TasteShould you be using a system with a long life filter we recommend regular maintenance and decontamination of that filter to help prevent organic bacteria growth and odours. Our concern over long life filters is without laboratory or high level decontamination processes such as autoclave sterilisation you cannot be 100% sure the growing bacteria inside the filter has been killed, not to mention the repeated cleaning processes and down time required. These high temperature decontamination methods whilst highly effective against bacteria can in turn damage the filter media. Therefore it is good working practice to change the filter once every 2 months, or when the filter becomes hard to pull water through even if it is advertised as a long life filter. Pure Clear Filters does not manufacture or use long life filters for the reasons mentioned above and we consider anything over 1000 litres to be long life, we would also recommend that you change our filters on a 2 month basis.
