Description
Product Overview
Culligan’s 5‑micron sediment filter is engineered to capture fine particles such as rust, sand, silt and scale that can compromise water quality and strain plumbing fixtures. Housed in a robust white plastic shell, the filter measures 5.25″ D x 9.75″ W x 2.88″ H and features a 2.5‑inch cutting diameter for plate‑mount installation. Certified by IAPMO and meeting NSF/ANSI Standard 42 for material safety, each filter provides up to 8,000 gallons of service, roughly two months of typical household use.
Usage
This filter is ideal for residential whole‑house systems, especially in areas with city or well water that contains visible sediment. Install it in Culligan models HF‑150A, HF‑160, HF‑360A or HF‑365 to protect downstream appliances, extend the life of reverse‑osmosis membranes and improve the taste of tap water. Homeowners, renters and property managers will appreciate the straightforward plate‑mount design that requires no tools beyond a screwdriver and the included change‑reminder sticker.

FAQ
How often should I replace the filter?
The filter is rated for up to 8,000 gallons of water, which typically translates to about two months of use in an average household. Replace it when the change‑reminder sticker indicates or if water flow noticeably decreases.
Is this filter compatible with other brands?
This specific model is designed for Culligan whole‑house systems listed above. While the dimensions may fit other plate‑mount filters, we recommend using it with the specified Culligan models for optimal performance.
Does the filter remove chemicals or improve taste?
The 5‑micron sediment filter targets physical particles such as sand, rust and silt. It does not remove dissolved chemicals or improve taste beyond eliminating gritty or cloudy water. For chemical reduction, pair it with an activated‑carbon or reverse‑osmosis system.
Can I install the filter myself?
Yes. The filter comes with a plate‑mount design that requires only a screwdriver. Follow the included instructions, ensure the water supply is shut off, and secure the filter in the designated housing.
What does NSF certification mean?
NSF certification verifies that the filter meets strict standards for material safety and structural integrity. It does not imply testing for contaminant removal beyond the sediment rating.
