Product Overview
The Culligan FM-25 water filter cartridge is engineered for households that demand pure, great‑tasting water straight from the tap. Constructed from durable plastic housing with a sleek chrome finish, the cartridge integrates seamlessly into the FM-25 plate‑mount faucet system. Measuring 2.75″ D × 2.75″ W × 3.5″ H and weighing just 4.8 oz, it is compact yet robust. Certified by ANSI and NSF to meet standards 42 and 53, the filter employs a multi‑stage media that targets a broad spectrum of contaminants, including atrazine, chlorine, lindane, lead, Class I particulates, turbidity, and off‑flavors or odors. Each cartridge is designed for a lifespan of up to 200 gallons or approximately two months, depending on water quality and usage patterns.

FAQ
How often should I replace the FM-25 cartridge?
The cartridge is rated for up to 200 gallons of water or roughly two months of typical household use. Replace it when the indicator light on your Culligan system signals a change is needed, or if you notice a decline in water taste or flow.
Will this filter remove all contaminants from my water?
The FM-25 targets a wide range of common contaminants, including atrazine, chlorine, lead, and particulates, but it does not remove dissolved minerals such as calcium or magnesium. For full‑scale softening, consider a dedicated water‑softener in addition to this filter.
Is the filter compatible with other faucet models?
This cartridge is specifically designed for the Culligan FM-25 plate‑mount faucet system. While it may physically fit other plate‑mount designs, optimal performance and certification are guaranteed only with the compatible Culligan model.
Do I need any tools or additional parts for installation?
No tools are required. The cartridge comes with a pre‑assembled plate‑mount that simply twists onto the faucet base. All necessary components are included in the package.
Can I install the filter myself?
Yes. The installation process is straightforward: turn off the water supply, remove the existing cartridge, align the new plate‑mount, twist it into place, and turn the water back on. Detailed step‑by‑step instructions are provided in the user manual.
