MF FIX Pre-Filter Housing 20 Inch Cartridge PP Spun for Water Purifiers Solid Filter Cartridge  (5, Pack of 1)

A water filter cartridge is the central component of a water filtration system, designed to remove unwanted particles, sediments, chemicals, and contaminants from water as it flows through the filter housing. Cartridges are typically made from various materials such as polypropylene, carbon, ceramic, and stainless steel, allowing them to address different filtration needs—from sediment removal and chemical absorption to elimination of bacteria and dissolved solids. These cartridges work by trapping impurities within their media or on their surfaces, effectively producing clearer, cleaner water suitable for drinking, cooking, or industrial use. The cartridges come in many types, including spun, pleated, wound, membrane, and activated carbon filters, each serving specific purposes such as sediment removal, taste and odor reduction, or high-efficiency contaminant capture. Filter cartridges are easy to replace and maintain, making them ideal for household, commercial, and industrial water treatment applications.
