Nelsen Dirt Cart, 9-3/4 Spn Poly, 50 Mic

The Nelsen Dirt Cartridge is a 9-3/4" spun polypropylene sediment filter rated at 50 microns, manufactured by Durable Mfg. Co. Wound from a durable polypropylene cord around a rigid polypropylene core, it captures coarser sediment effectively while offering broad chemical compatibility, all at an economical price point that makes regular replacement easy on the budget.

Dependable Sediment Removal

This spun-poly cord cartridge is ideal for removing fine sediment such as sand, silt, scale, unseen sludge, and rust particles from your water. Its 50-micron rating makes it well-suited as a first-stage or pre-filter that protects downstream equipment like membranes, softeners, and finer cartridges from premature fouling. Because it is built entirely from polypropylene, it is compatible with most acids, alkalis, corrosive fluids, and gases, broadening its usefulness well beyond standard residential water.

• Spun polypropylene cord wound over a rigid poly core
• 50-micron rating for coarse sediment capture
• Standard 2.5" diameter x 9.75" length
• Removes sand, silt, scale, sludge, and rust
• Compatible with most acids, alkalis, and corrosive fluids
• Economical choice for agricultural, photographic, and residential use
• Drops into standard slim-line 10-inch filter housings

The Nelsen brand cartridge drops into standard slim-line 10" housings, making it a versatile and affordable option for whole-house pre-filtration and many point-of-use setups. Using a coarse sediment filter ahead of finer media is a smart strategy, since it captures the larger particles that would otherwise clog and shorten the life of more expensive downstream cartridges and membranes. For best results, replace the cartridge when you notice reduced flow or a rise in pressure drop, which indicates it has captured its capacity of sediment. Keeping a fresh sediment filter in service extends the life of costlier components and helps your entire water-treatment system run cleanly and reliably.

Stocking several of these affordable cartridges makes it easy to stay ahead of maintenance, so you can swap a clogged filter the moment flow begins to drop. As a first line of defense in whole-house and point-of-use systems alike, this 50-micron spun-poly cartridge offers dependable sediment protection at a price that makes regular replacement effortless. For homeowners and farmers alike, it delivers practical, no-fuss sediment protection that quietly extends the life of everything downstream of it. Because it is built entirely from polypropylene, it also handles a far wider range of fluids than ordinary filters, broadening its usefulness well beyond standard residential water duty.
