The Pentek R50 is a 50-micron rated string-wound sediment filter. Its spun polypropylene yarn construction around a tin-plated steel core provides true graded-density filtration, trapping larger particles on the outer layers and finer particles closer to the core. This makes it ideal for reducing rust, sand, silt, scale, and dirt from well water or heavily sedimented municipal supplies before they reach your plumbing and appliances.

The Pentek R50 should typically be replaced every 3 months, though the exact lifespan depends on your incoming water quality and household usage. If you notice a drop in water pressure or visible discoloration on the filter cartridge, replace it sooner. For homes with heavy sediment or well water, more frequent changes may be necessary to maintain optimal flow and protect downstream filtration equipment.

The Pentek R50 measures 9-7/8" in length with a 2-1/2" outer diameter, making it compatible with standard 10-inch Big Blue-style and slim-line whole house filter housings. It is a drop-in replacement for Pentek/Pentair standard-size housings and fits most industry-standard 10" sumps from other manufacturers that accept 2.5" x 9.75" cartridges.

The Pentek R50 supports a maximum flow rate of up to 8 GPM in standard applications, with a maximum operating temperature of 165°F (74°C) and a maximum pressure rating of 125 psi. These specifications make it suitable for both cold and hot water whole house applications, delivering whole-home sediment protection without significantly restricting household water flow.

No, the Pentek R50 is a dedicated sediment filter and does not remove chlorine, chemicals, lead, or improve taste and odor. It is specifically engineered for mechanical particulate removal down to 50 microns. For chlorine, taste, or chemical reduction, pair the R50 with a carbon-based whole house filter downstream, such as a Pentek carbon block or GAC cartridge, for complete multi-stage whole house filtration.
