Pentek C1 Carbon Filter Cartridge, 9-3-4 x 2-1-2, 5 Micron (4, 1 Pack)
C1 Carbon Filter Cartridge
Carbon-impregnated cellulose cartridge that handles both sediment and chlorine in a single 9-3/4 x 2-1/2 inch form factor. Pack of 4 cartridges for residential chlorinated water supplies.
Dual-purpose filtration in a single cartridge
Carbon-Impregnated Media
Cellulose fibers infused with activated carbon reduce chlorine taste and odor while capturing sediment particles down to 5 microns in a single pass.
Low Pressure Drop
Open fiber structure allows high flow rates without sacrificing filtration efficiency. Good for whole-house or point-of-use applications where flow matters.
Reinforced Construction
Polyester backing and external netting give the cartridge structural integrity and extend dirt-holding capacity beyond standard carbon blocks.
General Purpose Design
Built for chlorinated municipal water. Handles taste, odor, and fine sediment in a single economical cartridge. Pentek C Series reliability.
Standard 9-3/4 inch cartridge housings
The Pentek C1 fits any standard 10-inch filter housing with a 2-1/2 inch outer diameter. Compatible with Pentek, Culligan, GE, Omnifilter, and most residential filter housings using the 155002-43 or equivalent cartridge size. Confirm your housing accepts 9-3/4 x 2-1/2 cartridges before ordering.
Replacement schedule for the C1 cartridge
Standard Residential Use
Replace the Pentek C1 cartridge every 3 to 6 months depending on water quality and usage. Chlorine levels, sediment load, and flow rate all affect service life.
High-Sediment Conditions
If you notice pressure drop or reduced flow before the 3-month mark, replace sooner. Heavy sediment will clog the carbon-impregnated media faster than chlorine alone.
Pack of 4 Cartridges
One year of filtration coverage for most households at quarterly replacement intervals.
Dual-Action Media
Carbon and sediment filtration in a single cartridge reduces housing footprint and cost.
Drop-In Replacement
Standard size fits most 10-inch housings. No modifications or adapters required for installation.
