Carbon Block Water Filters: Model, Media and Compatibility

This guide explains the Carbon Block Water Filters model and the details to check when choosing a replacement. Match the media, dimensions and connection code to your equipment; similarly named cartridges may have different fittings or treatment applications.

Carbon Block Water Filters are made of Coconut Shell Activated Carbon.

Model Number Breakdown CB-2025-5

CB ► Carbon Block

2025 ► Size, 20” by 2.5”

5 ► 5 Micron Carbon Block

The part number on our filters represents the media (first two letters); the length and diameter (first two numbers); and micron rating (last number).

What are the Carbon Block Water Filters applications?

• Ideal for use in drinking fountains as well as under the counter systems with 10" x 2.5" housings.
• Ideal for whole house water filters and higher flow rates (10" x 4.5" or 20" x 4.5" filter).
• Work for treated water (municipal, town, government water).

Recommendations

• • If installed under the sink, this filter needs a dedicated drinking faucet to filter water at 2.8 LPM.
  • If installed for the whole house, this filter needs a pre-filter (sediment filter) to protect the carbon filter.

• • If installed without a sediment pre-filter, dirt will cover the carbon pores and will prevent them from adsorbing impurities and chemicals.

Specifications

• • Reduce Chlorine, Taste, Odours.
  • Flow Rate:
    • 10" x 2.5" filters work at flow rates of 2.8 LPM.
    • 10" x 4.5" filters work at flow rates of 30 LPM.
    • 20" x 4.5" filters work at flow rates of 60 LPM.
  • Operating Temperature: 2°C to 38°C
  • Maximum Pressure: 125 psi
  • Model: Element filter for housings
  • Certification: ANSI and NSF 42 for chlorine taste and odours.

What's the Carbon Block Filtration Media?

• When water passes through the Carbon Block Filters, water is forced through the small pores of the Coconut Shell Activated Carbon Block Cartridge, where mechanical filtration and physical/ chemical adsorption reduce chlorine, taste and odour, sediments, and a wide range of contaminants of concern including VOCs.

How often should I replace the filters?

• Replacement Frequency depends on water quality and usage.
• Recommendation:
  • 10" x 2.5" Every Year.
  • 10" x 4.5" Every 6 months.
  • 20" x 4.5" Every Year.
