Discard used filter cartridge. Remove the sump o-ring, wipe clean and set aside.
Wash housing with dish soap and warm water using a nonabrasive sponge or cloth. Rinse thoroughly
If unpleasent odor is present disinfect filter housing. Fill 1/3 with water. Add about 1 tablespoon of bleach and scrub to disinfect. Rinse thoroughly
Lubricate o-ring with clean silicone grease and place back onto the sump housing. (Check for cracks or imperfections on the o-ring while lubicating, and replace o-ring if damaged.)
Insert new filter cartridge ensuring that it is seated properly in the sump housing.
Screw the sump housing back onto the cap and hand-tighten. Do not use the filter wrench to prevent over tightening.
Turn on the water supply and check for leaks before leaving the installation.

Product Details

USWF-MB30-1025 is a 30 micron 10"x2.5" melt blown sediment replacement filter that is proudly manufactured in the USA. It is made from FDA Title 21 compliant 100% melt blown polypropylene and doesn't use any surfactants, binders, or adhesives to create an exceptional product independently tested to NSF / ANSI standards 42, 61, and 372.
USWF melt blown filters utilize staged depth loading for maximum dirt holding and filter efficiency. The outermost layers of the filter are made of larger fibers to trap larger particles while the innermost layer traps the fine particles down the filter's micron rating. Most of the competition only has 3 stages of filtration, but USWF melt blown filters include an additional layer. This fourth layer of filtration provides a more consistent distribution of dirt through the filter improving its efficiency without sacrificing any dirt holding capacity.
This American made filter is a compatible replacement for other popular polypropylene sediment filters like the Pentek P30, Hydronix SDC-25-1030, and more.

Frequently Asked Questions

What is the micron rating of the USWF 30 Micron 10"x2.5" Melt Blown Sediment Filter, and what does it remove?

The USWF 30 Micron 10"x2.5" Melt Blown Sediment Filter has a 30-micron nominal rating, making it ideal for reducing larger sediment particles such as sand, silt, rust flakes, scale, and dirt from your water supply. Its melt blown polypropylene construction provides gradient density filtration, capturing coarse particles on the outer layer and finer particles toward the core. This filter is well suited as a pre-filter in whole-house systems or as the first stage in multi-stage setups where heavy sediment loads are present.

How long does the USWF 30 Micron Melt Blown Sediment Filter last before replacement?

The USWF 30 Micron 10"x2.5" Melt Blown Sediment Filter typically lasts 3 to 6 months, depending on your incoming water quality and daily usage. Households with high sediment levels or well water may need to replace it closer to the 3-month mark, while homes on municipal water with lower turbidity can often stretch it to 6 months. A noticeable drop in water pressure is the most reliable indicator that it’s time for a replacement.

What size housing is this USWF sediment filter compatible with?

This USWF filter is built to the industry-standard 10" x 2.5" size, making it compatible with virtually all standard under-sink, countertop, and whole-house filter housings that accept 9.75"–10" cartridges with a 2.5" outer diameter. It fits popular housings from Pentek, Culligan, Watts, American Plumber, and most other 10-inch slim-line systems, offering a universal replacement option for sediment pre-filtration.

Is the USWF 30 Micron Melt Blown Sediment Filter NSF certified?

The USWF 30 Micron Melt Blown Sediment Filter is manufactured from 100% pure polypropylene that is FDA-compliant for food-contact applications. While the cartridge itself is not NSF/ANSI 42 certified, it is produced in facilities using NSF-listed materials, ensuring safe, food-grade performance for potable water sediment reduction. It contains no binders, adhesives, or surfactants that could leach into your water supply.

Should I use the 30 micron USWF filter alone or pair it with a finer filter?

For best results, the USWF 30 Micron 10"x2.5" Melt Blown Sediment Filter should be used as a first-stage pre-filter paired with a finer 5-micron or 1-micron sediment or carbon block filter downstream. The 30-micron rating handles the bulk of large debris, extending the life of your finer filters and any carbon or reverse osmosis stages that follow. If your water has only light sediment, it can also be used as a standalone whole-house sediment filter.
