Why These Carbon Filters Can Be Inter-Changed Will It Fit My Existing Water Filter? Benefits Of Our Filter Anti SCALE Option Ordering Details WAIT My filter looks more like this Why These Carbon Filters Can Be Inter-Changed Firstly: in the bad old days water filters would come in all shapes and sizes. The aim was to force customers to return to particular manufacturers. However in recent years there has been a growing move to standardise the sizes of filter cartridges. Now about 80% of all cartridges are the "universal ten inch size". (Note: Why they are called "ten inch" is a mystery as they are actually 9 and three quarter inches high!) Secondly: the great majority of water filters are made from carbon. And the great majority of carbon filters basically consist of burnt coconut shell. It is a question of exactly how it is moulded into the required filter shape during the filter manufacturing process. For example, the carbon might be cut into grains and placed inside a hard cartridge case (Granular Activated Carbon / AC). Or they might be compressed into Carbon Block and typically be surrounded by a mesh - as is the case with our specially made "10 inch" types - see above right. While Carbon Block is now generally seen as being a superior method of filtration over GAC, they basically do the same job. The point is that as long as the size of the cartridge is correct, one type can be changed for the other. Benefits of Your New Replacement Filter Top quality US designed filter Green!
