The CBB-4N-S-25W is a complete whole-house water purification system combining multi-stage filtration with efficient ultraviolet (UV) sterilization. Featuring three 20-inch Big Blue filter housings mounted on a durable powder-coated steel bracket, plus a reliable 25W stainless steel UV sterilizer, this system removes sediment, chemicals, and harmful microorganisms to deliver safe, clean, and great-tasting water throughout your home.

Key Features:

• Four-stage water purification for whole-house protection

• Stage 1: 50-micron sediment filter removes large particles such as sand, rust, and silt

• Stage 2: Carbon block filter reduces chlorine, chemicals, odours, and organic compounds

• Stage 3: 5-micron sediment filter removes finer particles for clearer water

• Stage 4: 25W stainless steel UV sterilizer destroys bacteria, viruses, and pathogens without chemicals

• Suitable for municipal and borehole water (borehole use requires water analysis submission)

• Powder-coated steel bracket offers corrosion resistance and secure wall mounting

• Filtration stages require no electricity; UV sterilizer requires power

• Ideal for whole-house installation, ensuring clean, microbiologically safe water at every tap

Stages of Water Treatment:

• Stage 1: 50-micron sediment filter traps coarse debris, protecting downstream filters and plumbing

• Stage 2: Carbon block filter removes chlorine, bad tastes, odours, pesticides, and volatile organic compounds (VOCs)

• Stage 3: 5-micron sediment filter captures fine particles for polished water clarity

• Stage 4: 25W UV sterilizer inactivates bacteria, viruses, and other pathogens for microbiologically safe water

Sterilization Filter Details:

This system’s sterilization filter is a stainless steel UV light unit designed to disinfect your water efficiently and naturally. UV rays can destroy 99.99% of harmful micro-organisms without adding chemicals or altering your water's taste or odour. Ultraviolet light is a natural component of sunlight and is widely recognized as an effective, environmentally friendly solution for water disinfection.

The UV lamp operates at a wavelength of 254 nm, using a highly efficient UV radiator that kills microorganisms by disrupting their DNA. Water passes through a specially designed chamber ensuring intimate contact with the UV light. Bacteria and other living organisms absorb the UV energy, which destroys their ability to survive and reproduce. Additionally, chemicals and organic compounds absorb the UV energy and break down into smaller, harmless molecules, improving overall water quality.
