Description
The 3 Stage 20″ Big Blue Filter System on Frame (Excluding Cartridges) is a robust whole-house water filtration system designed to improve water quality for residential, commercial, and light industrial applications. Featuring three 20-inch Big Blue filter housings mounted on a heavy-duty powder-coated steel frame, this system allows you to customise the filtration process by selecting cartridges that best suit your water quality requirements.
By installing the appropriate sediment, carbon, or specialty filter cartridges, the system can effectively reduce sediment, chlorine, unpleasant tastes and odours, and other contaminants before water reaches your plumbing, appliances, or point-of-use treatment systems. The modular design makes cartridge replacement and maintenance simple while providing high flow rates for whole-house water filtration.
