NP5-BB-20 Nelsen Dirt Cart Filter Cartridge – Enhance Water Quality by Efficiently Removing Sediment

The NP5-BB-20 Nelsen Dirt Cart filter cartridge is designed to provide reliable sediment filtration for water treatment systems. Unlike generic filter cartridges, it features a 20-inch, 5-micron spun polypropylene construction that effectively captures dirt and particles, ensuring cleaner water flow. As a trusted component within filter cartridges and housings, this cartridge offers consistent performance and durability, reducing maintenance needs in your water softener or filtration setup.

Key Benefits

• Protects your water system from sediment buildup, extending equipment life
• Delivers precise 5-micron filtration for clearer, cleaner water
• Easy to install and replace in standard big blue housings
• Durable spun polypropylene construction resists tearing and degradation
• Maintains steady water pressure by preventing clogging
• Compatible with a wide range of residential and commercial water softeners

How It Works

The NP5-BB-20 filter cartridge operates by forcing water through its tightly wound spun polypropylene layers. These layers trap dirt, rust, sand, and other suspended particles down to 5 microns in size. By capturing sediment before it reaches sensitive components, the cartridge helps maintain the efficiency of your water softener or filtration system.

Installed inside a standard 20-inch big blue filter housing, this cartridge creates a reliable barrier that keeps impurities from circulating through your plumbing. Its design ensures minimal flow restriction while maximizing sediment removal.

What to Expect

Once installed, you will notice an immediate improvement in water clarity and quality. The filter reduces visible particles and sediment, protecting downstream equipment. During the first few weeks, the cartridge efficiently traps debris without impacting water pressure.

Over time, the cartridge will collect sediment until it reaches capacity, at which point replacement is recommended to maintain optimal filtration. Regular changes will keep your water system running smoothly and prevent costly damage or downtime.

What’s Inside

• Spun Polypropylene Media – Provides 5-micron filtration for effective sediment capture
• 20-Inch Big Blue Size – Fits standard large-capacity filter housings for broad compatibility

• Core Support Structure – Maintains cartridge shape and flow characteristics during use

How to Use

1. Turn off the water supply to your filter housing.
2. Relieve pressure by opening a nearby faucet or using the housing’s pressure release valve.
