The Pentek GS-10ALS-JG14 is a 5-micron granular activated carbon (GAC) inline filter with a rated capacity of 1,500 gallons or approximately 12 months of service life, whichever comes first. Its 5-micron rating effectively reduces chlorine taste and odor, sediment, and fine particulates, making it ideal for polishing water used in refrigerators, ice makers, RVs, and point-of-use drinking water systems.

The Pentek GS-10ALS-JG14 measures 10 inches in length with a 2-inch diameter and features built-in 1/4-inch John Guest (JG) quick-connect push-in fittings on both ends. This design eliminates the need for separate housings, adapters, or tools—simply push your 1/4-inch tubing into the fittings for a fast, leak-free installation in tight spaces behind refrigerators or under sinks.

The Pentek GS-10ALS-JG14 is manufactured by Pentair/Pentek using components tested and validated to NSF/ANSI Standard 42 criteria for aesthetic effects, including chlorine taste and odor reduction. The filter media and housing materials meet FDA requirements for food-contact applications, ensuring safe use with potable drinking water systems.

Pentek recommends replacing the GS-10ALS-JG14 every 12 months or after 1,500 gallons of throughput, whichever occurs first. Homes with chlorinated municipal water, high daily consumption, or ice makers running continuously may need to change it sooner if you notice reduced flow, returning chlorine taste, or cloudiness in ice cubes.

The Pentek GS-10ALS-JG14 operates at a maximum flow rate of 0.75 GPM, with a pressure range of 20–100 psi and temperature range of 40°F–100°F. These specifications make it perfectly suited for low-flow applications like refrigerator water lines, ice machines, and under-sink drinking water dispensers—not for whole-house or high-demand use.
