Overview
The Glacier Fresh GF-009X is a NSF-certified replacement water filter sold in a 4-pack, built with carbon fiber media and sized about 9.96 x 1.73 x 1.73 inches, weighing under a pound each.
The slim, cylindrical dimensions here are typical of an inline or refrigerator cartridge rather than a pitcher or under-sink system, and the 4-pack format suggests this is meant for buyers replacing filters on a recurring schedule. NSF certification points to third-party testing, though the listing doesn't specify which appliance models the cartridge is built to fit.
- NSF certified filtration
- 4-pack of replacement cartridges
- Carbon fiber filter media

Who it's for
Fits buyers who've confirmed the GF-009X's slim cartridge shape matches their appliance's filter slot and want four on hand for ongoing replacement. Not a fit without confirming that compatibility first.
