Pentair pool filters have long been a trusted choice for pool owners seeking crystal-clear water with minimal maintenance. Engineered for durability, efficiency, and superior performance, Pentair pool filters deliver reliable filtration across a variety of pool types — from compact residential setups to larger in-ground installations.
At the core of the Pentair filtration lineup are three main designs: cartridge filters, D.E. (diatomaceous earth) filters, and sand filters. Each type offers distinct benefits to suit differing maintenance preferences, water clarity goals, and pool sizes.
Cartridge filters, such as the popular Clean & Clear® Plus models, are designed for easy cleaning and high dirt-holding capacity. These filters use pleated fabric cartridges that trap debris efficiently and can be rinsed clean with a simple hose-off, reducing downtime and water waste compared with backwashing systems. Many feature robust fiberglass-reinforced polypropylene tanks and optimized internal flow design, ensuring long-lasting performance.
For pool owners seeking exceptional water clarity, Pentair’s D.E. filters like the FNS® Plus series provide superior filtration that captures microscopic particles traditional filters might miss. Diatomaceous earth media filters particles as small as 2–5 microns, delivering water that’s noticeably cleaner and clearer — ideal for swimmers who demand pristine conditions. These filters are engineered with curved grids and efficient internal designs to allow longer cycles between cleanings and lower operating costs.
Sand filters remain a classic solution for durability and low maintenance. Pentair sand models, such as Triton® II and Tagelus®, offer rugged performance with minimal upkeep. These systems leverage the natural filtering properties of sand — and in modern versions, enhanced media like glass can further improve filtration efficiency. Sand filters are especially appealing for large pools where longevity and simplicity are key considerations.
One standout attribute Pentair Pool Filters of Pentair pool filters is their Eco-Select designation and energy-efficient operation. Many models are designed to work with smaller pumps or lower speeds, reducing energy consumption and operating costs over time. Additionally, easy-access housings and streamlined maintenance procedures help pool owners spend less time servicing equipment and more time enjoying their water.
Whether you want low-effort maintenance, highest-level clarity, or durable long-life performance, Pentair pool filters provide versatile, high-quality solutions that keep your pool water sparkling clean year-round.
