20 Inch Water Filters

Our 20 inch water filters offer high-capacity filtration for medium to large flow systems, providing longer service life, improved sediment retention, and greater chemical absorption than standard 10" filters. Suitable for residential, agricultural, commercial, and light industrial applications, these cartridges are ideal for whole-house, borehole, tank-fed, and pre-filtration setups.

Available in both Slimline (standard diameter) and Big Blue (high-capacity) formats, our 20" filter range includes a variety of options such as string wound, melt-blown, pleated sediment, carbon block, GAC, and specialty media cartridges like iron removal, scale prevention, and ceramic filters.
