Nelsen Dirt Cart 9-3/4 50mic Spn Ply

The Nelsen NP50 sediment cartridge is a 9-3/4" melt-blown polypropylene filter rated at 50 microns, an economical, high-performing choice for removing dirt, sand, silt, and rust from household and light-commercial water. Manufactured by Pureteck and built to the standard 2.5" x 9-3/4" housing dimensions, it drops into a huge range of common filter housings, making it one of the most versatile sediment cartridges available.

Graded-Density Depth Filtration

What sets melt-blown cartridges apart is their graded density. The media is wound progressively denser toward the center, so the filter uses its entire depth to trap particles, capturing larger debris on the outside and progressively finer particles toward the core. This depth-loading design translates directly into high dirt-holding capacity and longer service life compared with surface-only filters that clog at the face. The thermally bonded fibers are locked in place and will not migrate into your water, an important assurance for potable use.

• 50-micron rating for general sediment removal
• Melt-blown polypropylene with graded-density depth construction
• Standard 2.5" diameter by 9-3/4" length housing fit
• NSF certified for confidence in potable applications
• Self-supporting media requires no separate center support tube
• No adhesives, binders, or anti-static agents used

Because the thermally fused fibers are self-supporting, there is no separate center core that could fail or contaminate the water, and the all-polypropylene construction offers broad chemical compatibility across a wide range of applications. As a pre-filter, the NP50 protects downstream carbon, softeners, and RO membranes from particulate fouling, extending their life and keeping your water clear, which makes it a smart first line of defense in almost any treatment train. NSF certified, budget-friendly, and widely compatible, the Nelsen NP50 is a dependable everyday sediment cartridge that delivers reliable performance changeout after changeout.

At 50 microns, the NP50 is well suited as a primary sediment stage for municipal water or as part of a staged setup on well water, where it captures the visible grit and rust that protect everything downstream. Replacement is simple and economical, and a climbing pressure drop or visibly loaded cartridge tells you when it is time. Because it fits the ubiquitous 9-3/4-inch housing standard, it slots into the vast majority of residential and light-commercial systems without adapters. Affordable, NSF certified, and reliably effective, the Nelsen NP50 from Pureteck is a sediment cartridge you can buy and use with complete confidence.
