Description

Big Blue/High Flow Triple 20″x4.5” Whole House Water Filter

High-flow water filtration for residential, commercial and industrial applications.

Big Blue filtration systems are designed for properties requiring high water flow and reliable filtration throughout the entire premises.

Installed on the main water supply, these systems help reduce sediment, chlorine, unpleasant tastes and odours, delivering improved water quality to taps, showers and appliances throughout your property.

Available in single, twin and triple configurations, with flow rates of up to 150 litres per minute on suitably rated systems.

Key Benefits

5 Micron Pleated Washable Sediment Filter

  • Reduces dirt, rust, sand and suspended sediment.

  • Helps protect plumbing, tap washers, hot water systems and appliances from sediment buildup.

  • Washable and reusable, helping reduce ongoing maintenance costs.

5 Micron Carbon Block Filter

  • Reduces chlorine, improving water taste and odour.

  • Helps reduce certain organic contaminants, depending on cartridge specifications.

  • Provides additional fine particulate filtration for clearer water.

5 Micron Silver-Impregnated Carbon Block Filter

  • Incorporates silver for bacteriostatic protection, helping inhibit bacterial growth within the filter media.

  • Provides additional carbon filtration to improve taste and odour.

  • Particularly suited to selected rainwater and whole-house filtration applications.

Note: Silver-impregnated carbon is not a substitute for UV disinfection or other appropriate treatment of microbiologically unsafe water.

Choosing the Right Filtration System

The ideal filtration system depends on your water source, water quality, household water demand and the contaminants you need to address.

Our single, twin and triple Big Blue systems can be configured with different cartridges to suit your individual filtration requirements.

Better water for your home, family and future.

Actual flow rates and filtration performance depend on the system configuration, cartridge selection and operating conditions.
