Watco CB0505-24 Carbon Block Filter Cartridge 5 Micron

Product Description

The WATCO CB0505-24 is a 5-micron carbon block filter cartridge designed for residential and light commercial water filtration applications. It measures 5 inches in length by 2.5 inches in diameter and delivers mechanical and chemical filtration in a single stage. The carbon block construction reduces chlorine taste and odor, sediment, and other common water contaminants down to 5 microns. Plumbers and water treatment technicians install this cartridge as a drop-in replacement in standard 10-inch or equivalent filter housings during routine service intervals.

This cartridge fits standard undersink, whole-house point-of-entry, and countertop filtration systems that accept a 2.5-inch diameter cartridge. It is suited for potable water lines in residential kitchens, utility rooms, and light commercial settings where chlorine reduction and sediment control are required. Replacement intervals vary based on water quality and flow demand, but routine scheduled change-outs are standard practice in water treatment service work.
