Product Details

USWF-PP50-1045 is a 50 micron 10"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 Pentek R50-BB, Hydronix SPC-45-1050, and more.
Proudly made in America

Frequently Asked Questions

What is the micron rating of the USWF 10x4.5 Pleated Polyester Sediment Filter, and what does it capture?

The USWF 50 Micron 10"x4.5" Pleated Polyester Sediment Filter has a 50-micron rating, making it ideal for capturing larger particulates such as sand, silt, rust flakes, scale, and coarse sediment from your water supply. It is best used as a pre-filter in whole-house systems to protect downstream filters, softeners, and appliances from heavier debris, extending the life of finer filtration stages.

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

The USWF 50 Micron Pleated Polyester Sediment Filter typically lasts 3 to 6 months, depending on your household's water usage and incoming sediment levels. Because the pleated polyester media is washable and reusable, you can rinse the filter multiple times to extend its service life before replacement — a cost-effective benefit over standard spun or melt-blown sediment cartridges.

What housings is the USWF 10"x4.5" Pleated Sediment Filter compatible with?

This USWF pleated polyester filter features standard Big Blue dimensions of 10 inches in length and 4.5 inches in diameter, making it compatible with most 10" Big Blue-style whole-house filter housings. It fits popular housings from brands such as Pentek, Pentair, Culligan, American Plumber, and similar 10" x 4.5" systems used in residential and light commercial whole-house filtration setups.

Is the USWF 50 Micron Pleated Polyester Sediment Filter reusable?

Yes, one of the key advantages of the USWF 50 Micron Pleated Polyester Sediment Filter is that it is washable and reusable. Simply remove the cartridge, rinse off the trapped sediment with clean water, and reinstall it in your housing. This reusability makes it more economical and environmentally friendly than disposable sediment filters, though replacement is recommended once the pleats show visible wear or reduced flow.

Where should the USWF 50 Micron Sediment Filter be installed in my water system?

The USWF 50 Micron Pleated Polyester Sediment Filter is designed to be installed at the point of entry (POE) as the first stage of a whole-house filtration system. Placing it before carbon filters, water softeners, or reverse osmosis systems protects those components from coarse sediment damage and clogging, improving overall system performance and extending the lifespan of finer-rated downstream filters.
