Pure, Reliable Whole-House Filtration with PUREPLUS CTO20BB

Upgrade your home water experience with the PUREPLUS CTO20BB filter cartridge. Designed for standard 20" x 4.5" housings, this 5-micron coconut shell activated carbon block targets common water quality concerns found in municipal supplies. Expect water that tastes cleaner, looks clearer, and feels more refreshing from every faucet and shower. If your water source is well water, results may vary, and you may want to explore other options in our range.

What makes this filter effective

  • Filtration capacity: Reduces chlorine, as well as sand, rust, sediment, and color, helping improve taste and odor in tap water.
  • High-quality media: Made from 100% coconut shell-activated carbon blocks with a vast surface area. The carbon blocks work with advanced sintering technology for finer filtration of suspended particles and dirt.

Quality you can trust

Every filter is produced under ISO 9001 standards and undergoes rigorous testing. With 34 production steps, 400 PSI pressure tests, 10,000 water hammer tests, and 6 independent verifications, this cartridge is built for consistent performance in daily use.

Long-term use & maintenance

  • Filter up to 100,000 gallons, depending on water quality and household usage.
  • Recommended replacement every 6–12 months for typical home use to maintain peak performance.

Compatibility and installation

Fits any standard 20" x 4.5" heavy-duty filter housing and is compatible with models like FC25B, CB-BB-20, EPM-20BB, 155783-43, CBC-20BB, and other similar housings. A straightforward swap can help keep your home’s filtration system running smoothly.

Practical benefits for everyday use

From morning beverages to cooking and laundry, consistent filtration can contribute to a more approachable water experience. This cartridge is designed to be a dependable first stage in a broader filtration setup, potentially helping to protect downstream filters and appliances over time.

Environmental and value considerations

Choosing a reusable filtration cartridge can reduce bottled-water usage and support a cleaner kitchen routine, while providing a consistent level of filtration across daily tasks.
