Big Blue Water Filters

Big Blue water filters are heavy-duty, high-capacity filtration systems designed to treat large volumes of water at the point of entry (POE)—making them ideal for whole-house, borehole, commercial, and light industrial applications. Built to accommodate large-diameter cartridges, Big Blue housings deliver excellent flow rates with reduced pressure drop, longer service life, and fewer cartridge replacements.

We stock complete Big Blue filter housings in 10” and 20” sizes, along with a wide range of compatible cartridges for sediment removal, chlorine reduction, taste & odour improvement, iron control, and scale prevention. Available in single, dual, or triple-stage configurations, these systems can be tailored to suit your specific water quality needs—whether sourced from municipal supply, borehole, or rainwater harvesting systems.
