The Pentek product range includes sediment filters, carbon block cartridges, granular activated carbon filters, radial flow cartridges, deionization filters, lead reduction cartridges, reverse osmosis membranes, undersink drinking water systems, and a broad variety of replacement housings and accessories. These products are available in Standard, Slim Line, Big Blue, inline, bag filter, and quick-change formats to support both low-flow and higher-capacity filtration applications.

Big Blue heavy-duty housings are designed for large-capacity, high-flow, and heavy-sediment applications, while Standard and Slim Line housings offer practical filtration options for more compact residential and undersink installations.
