Founded in 1975, Pleatco has evolved from a regional manufacturer into a global leader in high-performance pool and spa filtration. Known as "The Clean Water Company," Pleatco’s reputation is built on a relentless commitment to engineering and science. Unlike standard "off-the-shelf" replacements, Pleatco designs their cartridges with proprietary technologies like the Free Flow Core and Point Bonded Filtration Fabric, which maximize water flow and dirt-holding capacity. In 2021, the brand reached a new milestone by joining the Pentair family, combining their innovative spirit with the resources of a global water treatment giant. Whether you are looking for the standard-setting Pleatco Advanced line or the revolutionary ULTRA series featuring Pure Pleat technology, Pleatco products are engineered to provide families with cleaner water and longer-lasting performance between cleanings.
