The Pentek HFPP-PR20 is a pleated polypropylene whole house filter cartridge with a 1 micron nominal rating. This fine micron rating makes it highly effective for reducing sediment, silt, sand, rust particles, and scale from your whole house water supply, delivering cleaner water throughout your home.

The Pentek HFPP-PR20 measures 20" in length with a 4.5" outer diameter (Big Blue size). It is specifically designed to fit Pentek Big Blue housings and other standard 20" x 4.5" whole house filter systems. The pleated polypropylene construction provides more surface area than standard spun or string-wound cartridges, resulting in higher dirt-holding capacity and longer service life.

The Pentek HFPP-PR20 typically lasts 3 to 6 months depending on your incoming water quality, sediment load, and household water usage. Homes with well water or high sediment levels may need to replace the cartridge more frequently. A noticeable drop in water pressure is the clearest sign that it's time for a replacement.

Yes, one of the key advantages of the Pentek HFPP-PR20 pleated polypropylene cartridge is that it can be rinsed and reused multiple times before needing full replacement. Simply remove the cartridge, rinse the pleats with clean water to flush out trapped sediment, and reinstall. This makes the HFPP-PR20 a cost-effective option compared to single-use sediment filters.

The Pentek HFPP-PR20 is rated for a maximum operating temperature of 145°F (62.8°C) and a maximum pressure of 125 psi. Its all-polypropylene construction contains no binders, adhesives, or surfactants, making it FDA-compliant for food-contact applications and ideal for whole house potable water filtration.
