Unicel UHD-SR50 50 Sq. ft. Replacement Filter Cartridge

Why Microban Protection? Water and an ample food source provide the ideal condition for bacteria to quickly multiply and grow. In fact, on an unprotected surface, some microbes can double in number every 20 minutes. And only when they鈥檝e multiplied to hundreds of thousands, can they actually be seen by the naked eye. The images below show bacteria growth on a standard pool filter cartridge versus a pool filter cartrdge infused with Microban antimicrobial protection over a 24 hour period. After viewing these images, you can see how Microban protection begins to work immediately, disrupting key bacterial cell functions so that bacteria are unable to grow or reproduce on the surface. While on the unprotected surface, bacteria quickly multiply.
