ICEPURE 1 Micron 20" x 4.5" Whole House CTO Coconut Shell Activated Carbon Filter Cartridge Replacement (1 Pack)

Overview

Meet the ICEPURE CTO20BB cartridge, a 1 micron coconut shell activated carbon filter designed for whole-house filtration in standard 20" x 4.5" housings. It aims to reduce chlorine taste and odor at every tap, helping water feel cleaner and more inviting for drinking, cooking, and bathing.

Certified materials and safe filtration

The cartridge carries IAMPO NSF/ANSI 42 certification for material safety and uses BPA-free materials. It aligns with global standards such as EC1935-2004, RoHS, and REACH, making it a solid choice for typical tap water filtration. If your water source is well water, note that large particulates like mud or sand may clog the filter more quickly, possibly affecting performance.

• NSF/ANSI 42 certification supports safe materials and chlorine reduction.
• BPA-free and RoHS/REACH compliant construction for everyday use.

Filtration technology and performance

This coconut carbon cartridge uses an advanced sintering process to help cut chlorine and related tastes and odors. It also captures finer particles and sediment to improve clarity and overall water quality. The design supports a high life span, with up to 100,000 gallons of filtration possible depending on water quality, and a recommended replacement window of 6–12 months.

• High-efficiency filtration that targets chlorine, tastes, and odors.
• Potentially long life between changes, based on water quality.

Quality standards and brand

ICEPURE applies stringent testing across multiple stages to ensure reliability. As an independent brand, the filter is designed for compatibility with a wide range of 20" x 4.5" whole-house systems and is suitable for models like FC25B, CB-BB-20, DB20P, EP-20BB, and more.

• Five inspection and testing stages support consistent quality.
• Independent brand focused on compatibility and performance.

Usage and compatibility

This cartridge is built for standard 20" x 4.5" entire-house filtration setups. If you own a compatible system, ICEPURE is widely interoperable with numerous housing units and associated model lines. Always verify fitment with your specific housing and model list.

• Compatible with multiple standard whole-house housings.
• Easy replacement in compatible systems.

Usage note

For well water, filtration results may vary and performance could be reduced if the water contains large particulates. You may consider pre-filtration or alternative solutions if the water has significant sediment, mud, or sand content.
