FilterCor pleated water filters are perfect for light industrial applications, swimming pools, spas, and well water applications. To replace FilterCor PE Series pleated filters, we recommend Harmsco WaterBetter Series Filters. They are made in the USA and meet or exceed the performance of the FilterCor cartridges, but are offered at a lower price. Please contact our helpful customer service representatives who would be happy to help you select the right filter for your water needs.
