20" Replacement Filters

This category features large diameter (4.5") and small diameter (2.5") filter cartridges designed for standard 20 inch tall water filter housings. These high-capacity filters provide comprehensive filtration for whole-home or commercial water treatment systems.

The 20 inch size is a common standard that offers greater filter media surface area compared to their smaller 10 inch counterparts, resulting in extended filter life and higher flow rates. These filters are designed to remove contaminants, improve water quality, and ensure the longevity of water filtration systems. Shoppers can find a variety of filter media types including sediment, carbon, and specialty blends to meet their specific water treatment needs.
