4. 20" x 2.5" Standard Universal Size
Membrane Solutions 20" x 2.5" universal string wound filter cartridge fits most 20-inch filter housings, as a prefilter of reverse osmosis (RO) systems and whole house water filtration, as well as a variety of commercial and industrial water treatment systems. For the specific filtration precision, you can choose 1/5/10/20 microns according to your needs.
5. Long-Life Filter With Higher Dirt-Holding Capacity
Our high dirt-loading capacity sediment filters can last up to 40,000 gallons. The filtered capacity and change-out cycle depend on the inlet water quality. Replace the filter at least every six months to maintain performance. The string wound filter has a deep-graded honeycomb structure, dense near the inside core and more open and sparse near the outside edge, forming an effective depth filtration filter, catching larger particulates first and then smaller near the center core, effectively increasing the dirt holding capacity of the filter.
