Abstract
The present invention relates to a replacable cartridge for use in a photocatalytic fluid purification system. The cartridge is capable of modifying impurities in a fluid flowing through the cartridge in the presence of light. The cartridge includes a flexible, porous element having a semiconductor coating associated with it and a rigid support structure which supports the element. The cartridge may be used in a variety of fluid purification applications where photocatalysis has not heretofore been utilized.
