SKU: 015-027. This 5-inch carbon filter cartridge is a compact, high-performance replacement cartridge designed as a drop-in solution for standard 5" x 2.5" filter housings. Ideal as an under-sink post-filter, an RO pre-filter, or a portable/RV filtration cartridge, it provides reliable taste-and-odor improvement using activated carbon technology.

Performance highlights: engineered to reduce chlorine, unpleasant tastes and odors, and a range of organic contaminants (VOCs) while capturing fine sediment—delivering cleaner, better-tasting drinking water. Many 5" cartridges use coconut-shell or coconut-based activated carbon for superior adsorption of chlorinated compounds and improved flavor. This makes the cartridge a versatile replacement for household, RV, and countertop systems that accept 5" mini cartridges.

Compatibility & installation: designed to fit most standard 5-inch housings and common under-sink and reverse-osmosis housings, the cartridge installs quickly with minimal tools — a simple twist-and-seal or push-fit in many mini housings. Low pressure drop and compact size keep flow steady while maximizing contact time with the carbon media. Service life depends on local water quality and usage; typical replacement intervals range from a few months up to a year, or as specified by your system’s guidelines.
