HIGH QUALITY POOL & SPA REPLACEMENT CARTRIDGES
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’ve 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.
My cartridge filter says it is a Sta-Rite Posi-Flo II model PTM 50. It says that the replacement cartridge is WC 108-56S2X but that filter does not reach the top of the filter housing and water is allowed to go all around the cartridge and not through the filter. I'm confused. Any ideas?
Usually pool filter cartridges do not reach the top of the filter. The water enters the filter and then penetrates the cartridge before returning to the pool. Part number WC 108-56S2X is the correct cartridge for the PTM50.
