High-Performance Nelsen Dirt Cart Filter Cartridge for Superior Sediment Removal

Designed for water treatment systems that demand reliable sediment filtration, the NP1-BB-20 Nelsen Dirt Cart offers exceptional particle capture with its 20-inch 1-micron spun polypropylene construction. This filter cartridge efficiently protects your water softener and filtration setup by removing fine dirt and debris, ensuring cleaner water and prolonged system life. Its robust build and trusted filter cartridge design make it an essential component for maintaining optimal water quality.

Key Benefits

• Protects your water system from sediment buildup, reducing wear on downstream equipment
• Removes particles as small as 1 micron, ensuring superior filtration performance
• Durable spun polypropylene media withstands varying water conditions without degradation
• Easy to install and replace, minimizing system downtime and maintenance effort
• Compatible with standard 20-inch big blue housings for versatile system integration
• Enhances overall water clarity and quality by capturing dirt and fine particulates

How It Works

The NP1-BB-20 functions as a sediment filter cartridge within your water treatment system's housing, trapping dirt, rust, and other suspended particles. Water flows through the tightly wound spun polypropylene layers where contaminants are mechanically captured, preventing them from reaching sensitive components like water softeners or membranes.

Its 1-micron rating means even very fine particles are filtered out, which helps maintain system efficiency and reduces the frequency of costly maintenance or repairs. The cartridge’s pleated design maximizes surface area, allowing for longer service life before replacement.

What to Expect

Once installed, you will immediately notice clearer water with reduced sediment content. Over the first few days and weeks, the filter continues to capture smaller particles, improving water quality consistently. This cartridge is designed for steady long-term performance, with gradual pressure drop indicating when replacement is necessary.

Regular monitoring and timely replacement ensure your system stays protected, maintaining reliable flow rates and preventing sediment-related damage or clogging.

What’s Inside

• Spun Polypropylene Media – provides effective 1-micron filtration and resists clogging for prolonged use
• 20-Inch Big Blue Form Factor – fits standard housings, enabling easy integration and replacement
• Robust Core Structure – maintains cartridge shape under pressure, ensuring consistent filtration
• Seamless Construction – prevents bypass and ensures all water passes through the filter media

How to Use

1. Turn off your water supply and relieve pressure by opening a faucet downstream of the filter housing.
2. Remove the existing filter cartridge from the big blue housing by unscrewing the housing carefully.
3. Dispose of the old cartridge according to local regulations.
4. Insert the NP1-BB-20 cartridge into the housing, ensuring proper alignment and seating.
5. Reassemble the housing and tighten securely to prevent leaks.
6. Turn the water supply back on and check for leaks around the housing.
7. Flush the system briefly by opening a faucet until water runs clear before normal use.
