Molecular sieve type 13X has a 12% higher water capacity and a larger pore size. This larger pore allows the water to adsorb faster than the 4A and will adsorb larger molecules as well. Depending on the quantity and type of molecules present, these could react on the surface of the 13X during regeneration and not come off, thus reducing the sieves capacity over time. 13X is subject to contamination which renders it ineffective.
