Listing details to confirm
The listing’s 13.3 x 5 x 5 inches product dimensions and the separate filter specifications of 13 5/16" length, 5" outer dimension and 2 1/8" top/bottom opening use different levels of detail. The listing does not confirm that every named reference is an exact fit, so compare the installed cartridge’s part number and measurements.

There is only a single aggregate rating and no customer-comment summary. That small amount of rating evidence cannot establish a broader customer experience or confirm fit, filtration performance or durability. For buyers, checking measurements and part-number compatibility remains more informative.
