The Stefani Twin Whole House 20 Inch Filter System provides high-capacity, dual-stage water filtration for medium to large households and suitable commercial or light industrial applications. Designed for properties with higher water usage, it filters the incoming supply before water is distributed to taps, fixtures and appliances throughout the property.

The dual-stage system combines a 5 micron sediment filter with a 5 micron carbon block filter. The first stage helps reduce sediment, rust, sand, silt and algae from incoming water, while the carbon block stage targets chlorine, chlorine by-products, unpleasant tastes and odours. It is also designed to reduce specified organic and volatile organic chemicals, pesticides and herbicides.

With a flow rate of 38–40 litres per minute, the Stefani Twin Whole House 20 Inch Filter System supports higher household water demands while maintaining whole-property filtration. Its 4.5 x 20 inch cartridge format provides high-capacity filtration, with dedicated Stefani sediment and carbon replacement cartridges available for ongoing maintenance.

Lead-free construction provides added confidence for everyday water filtration, while 3/4 inch inlet and outlet connections allow the system to integrate with compatible plumbing. It operates within a specified pressure range of 10–175 psi and requires professional installation by a plumber.

Combining 5 micron sediment filtration, carbon block technology and high-flow performance, the Stefani Twin Whole House 20 Inch Filter System offers a practical dual-stage solution for cleaner, better-tasting water throughout the home or facility.
