Product Details

USWF-PP50-2045 is a 50 micron 20"x4.5" pleated polyester sediment replacement filter that is proudly manufactured in the USA. It is made from FDA Title 21 compliant polyester fabric pleated around a polypropylene core to provide a high quality filter independently tested to NSF / ANSI standards 42, 61, and 372.
Pleated filters offer the lowest pressure drop and highest flow rate of all sediment filter types by providing as much filtration surface as possible to maximize water flow. However because pleated filters offer no filtration gradient or depth they are best suited to filter sediment of uniform particle size.
USWF only carries pleated polyester filters. The synthetic filter media is bacteria resistant so that it can be used on both treated and untreated water supplies. The pleated polyester is also highly durable meaning that you may rinse and clean the filter once it becomes clogs to extend the filter life.
This American made filter is a compatible replacement for other popular pleated sediment filters like the Watts FM-BB-50-20, Hydronix SPC-45-2050, and more.
Proudly made in America

Choosing American-made products means investing in quality you can trust, while also supporting jobs and communities across the United States. American manufacturing is held to strict quality and safety standards, ensuring durable, reliable products built to last.

Frequently Asked Questions

What is the micron rating of the USWF 20x4.5 Pleated Polyester Sediment Filter?

The USWF 50 Micron 20x4.5 Pleated Polyester Sediment Filter has a 50-micron rating, making it ideal for capturing larger sediment particles such as sand, silt, rust flakes, and dirt from your water supply. This coarser micron rating allows for high flow rates while serving as an effective pre-filter to protect finer downstream filters and extend the life of your whole-house filtration system.

What are the exact dimensions and compatibility of this USWF sediment filter?

This USWF filter measures 20 inches in length and 4.5 inches in diameter (20" x 4.5"), commonly known as a "Big Blue" size. It is compatible with standard 20" x 4.5" whole-house filter housings, including popular systems from Pentek, Big Blue, American Plumber, and similar-sized housings. Always confirm your housing dimensions before purchase to ensure a proper fit.

How long does the USWF 50 Micron Pleated Polyester Sediment Filter last?

The typical service life of the USWF 50 Micron 20x4.5 Pleated Polyester Sediment Filter is approximately 6 months or up to 75,000 gallons, depending on your water quality and usage. Homes with high sediment levels, well water, or heavy water consumption may need to replace the filter more frequently. Regularly inspecting the filter and monitoring for reduced flow or pressure drops will help you determine the optimal replacement schedule.

What is the pleated polyester media and why is it beneficial?

The USWF filter uses high-quality pleated polyester media, which offers several advantages over traditional spun or melt-blown filters. The pleated design significantly increases the surface area, allowing for greater dirt-holding capacity, longer filter life, and improved flow rates. Polyester media is also highly durable, resistant to bacterial growth, and performs reliably across a wide temperature range (40°F to 125°F), making it an excellent choice for whole-house sediment filtration.

Can the USWF Pleated Polyester Sediment Filter be cleaned and reused?

Yes, one of the key benefits of the USWF pleated polyester sediment filter is that it can be rinsed and reused multiple times before replacement, making it a cost-effective and eco-friendly option. Simply remove the filter from the housing, gently rinse it with clean water to wash away trapped sediment, and reinstall it. However, once the pleats show signs of damage, discoloration, or reduced flow even after cleaning, it's time to replace the filter to maintain optimal filtration performance.
