Pentair 155109-43 Gac Cartridge Filter 20 Micron

Product Description

The PENTAIR 155109-43 is a granular activated carbon (GAC) cartridge filter designed for inline plumbing filtration applications. It measures 2-7/8 inches in outside diameter and 9-3/4 inches in length, fitting standard cartridge filter housings used in residential and light commercial water treatment systems. Rated at 20 microns, this cartridge targets sediment while the activated carbon media adsorbs chlorine taste and odor compounds. It is installed by licensed plumbers and water treatment technicians performing point-of-use or point-of-entry filter maintenance. Operating temperature range is 40 degrees F minimum to 125 degrees F maximum.

This cartridge is suited for residential drinking water systems, under-sink filter assemblies, and whole-house filter housings that accept the standard 2-7/8 inch OD by 9-3/4 inch form factor. The GAC media provides broad-spectrum absorption for taste, odor, and fine sediment reduction, making it appropriate for municipal water supplies where chlorine and particulate loads are common concerns. Service intervals vary by water quality and flow demand; replacement is typically performed during scheduled filter maintenance.
