You should consider the Microban version of this filter!
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.
I have a sta-rite cartridge filter. the replacement cartridge is WC108-53SIX. Also on the metal plate attached to to filter cover has eff. filter area 137 sq ft. I am not sure which replacement filter would be the correct one.

My present filter’s size is 8 1/2” x 31” x 4” center. My filter casing is a Teel. 135 sq ft & 150 psi. Which filter is the correct number?

Hi, Bob. This cartridge is close in dimensions but not exact, so it will NOT fit. We do not have a cartridge that matches your exact measurements, please provide the filter model so that we can locate the replacement.

I have a "Posi Flo" filter that specifies a "135 TXR" replacement cartridge. Does this filter qualify as a replacement?

Just to be sure ------------- I have a Sta-Rite PTM 135 that calls for a Posi*Flo ii filter, part # WC108-7052X. Is your NFC2570 the correct replacement? Thank you.

Yes that is the correct cartridge for your filter.
