The AMPAC USA 20" BB Carbon Block (CB-520-BB) is a high-capacity jumbo activated carbon block filter cartridge for Big Blue 4.5-inch x 20-inch filter housings, providing chlorine, chloramine, taste, odor, and VOC reduction for whole-house and commercial water treatment systems. The compressed carbon block matrix creates a uniform flow path that maximizes contact time and adsorption efficiency compared to loose granular activated carbon cartridges.
Specifications:
- Format: Big Blue 4.5" x 20" jumbo cartridge
- Media: Compressed activated carbon block
- Reduces: Chlorine, chloramines, taste, odor, VOCs, THMs, and disinfection byproducts
- Fits standard 20-inch Big Blue and Jumbo filter housings
The 20-inch Big Blue format provides significantly higher flow rate and longer service life than standard 10-inch carbon cartridges, making the CB-520-BB ideal for whole-house pre-filtration applications where maintaining household flow rates is essential. Carbon block construction prevents channeling that can occur in loose GAC cartridges, ensuring all water contacts the activated carbon media.
Install after a sediment pre-filter to protect the carbon block from particulate plugging. Replace every 6–12 months depending on chlorine concentration and flow volume. Contact AMPAC USA at (909) 548-4900.
