RonaquaSediment Water Filter Cartridge 6 Pack 5 Micron RA-6S-5

Q: Will these fit my ge model gxwho4f housing ?

It fit my Culligan water filter with no problem. The filter measures 10 inches by 2 1/2 wide. Try taking your old one out and take it's measurement. They usually fit all standard filter models.

Q: Will this replace a whirlpool whkf-gd05 standard capacity cartridge?

This is the Whirpool description. "Fits Whirlpool WHKF-DWHV and many major brands of standard capacity whole home water filtration systems (2.5" x 10" systems)." So yes, it should. My old filter is actually 9.75 x 2.5 but this one also fits.
