The Big Blue filtration systems can be used on Borehole water, subject to a water analysis being submitted to us.

3 Stage Big Blue Water Filtration System With 55W UV Sterilizer, Sediment Filters & Carbon Filter (Whole House, 20 Inch) Aluminium/Stainless Steel Bracket

• The CBB-4N is a comprehensive whole-house water filtration system featuring three 20-inch Big Blue filter housings mounted on a durable aluminium/stainless steel bracket, combined with a powerful 55W stainless steel UV sterilizer. This system efficiently removes sediment, chemicals, and harmful microorganisms to provide safe, clean, and fresh-tasting water throughout your home.

  Key Features:

  • Four-stage water purification for whole-house protection

  • Stage 1: 50-micron sediment filter removes sand, rust, and silt

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

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

  • Stage 4: 55W stainless steel UV sterilizer destroys 99.99% of harmful bacteria, viruses, and pathogens without chemicals

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

  • Lightweight and corrosion-resistant aluminium/stainless steel bracket for easy and secure mounting (Bracket choice is dependent on availability)

  • Filtration stages require no electricity; UV sterilizer requires power

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

  Stages of Water Treatment:

  • Stage 1: 50-micron sediment filter traps large particles, 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 sediment for polished water clarity

  • Stage 4: 55W UV sterilizer inactivates bacteria, viruses, and other pathogens for microbiologically safe water

  Sterilization Filter Details:

  This system uses a stainless steel UV light unit to disinfect your water naturally and efficiently. UV rays destroy 99.99% of harmful micro-organisms without adding chemicals or affecting water taste or odour. Ultraviolet light is a natural part of sunlight and is a widely accepted, environmentally friendly method for water disinfection.

  The UV lamp emits radiation at a wavelength of 254 nm, using a highly efficient UV radiator to disrupt microbial DNA. Water flows through a specially designed chamber, ensuring intimate contact with the UV light. This exposure destroys or inactivates bacteria and other organisms, preventing reproduction. Additionally, UV energy breaks down certain chemicals and organic compounds into harmless molecules, improving overall water quality.

  Technical Specifications:

  • Maximum pressure: 6 bar

  • Maximum flow rate: 2720 litres per hour

  • Big Blue filter housing port size: 25 mm (1 inch BSP)

  • UV sterilizer power consumption: 55 watts

  • Recommended cartridge replacement: Every 6 to 12 months depending on water quality and usage

  • UV lamp replacement: Annually

  What’s Included:

  • 3 x 20-inch Big Blue filter housings

  • 1 x 50-micron sediment filter cartridge

  • 1 x Carbon block filter cartridge

  • 1 x 5-micron sediment filter cartridge

  • 1 x 55W stainless steel UV sterilizer unit

  • 1 x Aluminium/Stainless Steel Bracket mounting bracket with screws (Bracket choice is dependent on availability)

Disclaimer: Big blue filters are intended for fine filtration and limits apply to water quality and quantity. Have your water tested before installing a big blue filter to ensure that it is the right solution. It is important to note that the volume of water put through the unit as well as the quality of the water will greatly influence the lifetime of the filters.
