HydroTech 20" Triple Whole House Water Filtration System Advanced Whole House Filtration for Cleaner, Better Water Throughout Your Home The HydroTech 20" Triple Whole House Water Filtration System is a premium high-capacity filtration system designed to provide comprehensive water treatment throughout the entire home. Featuring three specialised filtration technologies — MLSF Series, HFMF Series and EPC Series — the system combines progressive sediment filtration, high-flow multi-function contaminant reduction and advanced electropositive filtration. Designed for Australian homes, the system uses full-size 20" x 4.5" cartridges, providing excellent contaminant holding capacity while maintaining strong whole-house water flow. With a filtration capacity of up to 400,000 litres, the HydroTech system is designed for long-lasting whole-house filtration and reliable everyday performance. For superior durability, both the structural frame and protective outer cover are manufactured from 304 stainless steel and powder coated, providing excellent strength, corrosion resistance and long-term protection. Advanced 3-Stage Filtration Stage 1 – HydroTech MLSF Series Multi-Layer Sediment Filter The HydroTech MLSF Series provides the first stage of filtration, capturing sediment and suspended particles before they reach the more advanced filtration stages. Its multi-layer filtration structure provides progressive filtration from approximately 10 micron on the outer layer to 5 micron on the inner layer, delivering excellent dirt-holding capacity while maintaining good water flow. The MLSF Series is designed to help reduce: Dirt Rust Sand Silt Algae Sediment Suspended particles By removing larger contaminants first, the MLSF cartridge helps protect the downstream HFMF and EPC filtration media and supports longer-lasting system performance. Micron Rating: 5 Micron Stage 2 – HydroTech HFMF Series High-Flow Multi-Function Filter The HydroTech HFMF Series provides the primary multi-function treatment stage of the system. Designed specifically for high-flow whole-house applications, the HFMF Series combines advanced contaminant reduction with extremely high dirt-holding capacity, helping maintain strong household water flow while providing broad-spectrum filtration. The HFMF Series is designed to help reduce: Chlorine Cysts Fluoride VOCs Heavy metals Scale build-up Its high-capacity filtration media makes it particularly suitable for whole-house applications where both effective contaminant reduction and high water flow are important. Micron Rating: 0.22 Micron Stage 3 – HydroTech EPC Series Electropositive Advanced Filter The HydroTech EPC Series provides the final advanced filtration and polishing stage. Unlike a conventional activated carbon cartridge, the EPC Series features a specially treated electropositive non-woven outer filtration layer, combined with nano silver catalytic sintered activated carbon. The positively charged outer media helps attract and capture extremely fine negatively charged contaminants, providing an additional filtration mechanism beyond conventional mechanical filtration. The EPC Series is designed to help reduce: Bacteria Viruses PFAS Chlorine Chloramine VOCs Fine suspended contaminants Unpleasant taste and odour The combination of electropositive filtration media, nano silver technology and catalytic sintered activated carbon provides an advanced final filtration stage for comprehensive whole-house water treatment. Micron Rating: 0.5 Micron Three Specialised Filtration Technologies Unlike conventional whole-house systems that rely primarily on sediment and standard carbon filtration, the HydroTech system combines three specialised filtration technologies, with each stage performing a different role. MLSF Series – Progressive Sediment Protection The MLSF Series captures dirt, rust, sand, silt, algae and other suspended particles through its multi-layer filtration structure, helping protect the advanced filtration stages that follow. HFMF Series – High-Flow Multi-Function Filtration The HFMF Series provides broad contaminant reduction while maintaining the high flow required for whole-house applications. It targets chlorine, cysts, fluoride, VOCs, heavy metals and scale build-up. EPC Series – Advanced Electropositive Filtration The EPC Series provides the final advanced treatment stage using electropositive media together with nano silver catalytic sintered activated carbon, targeting fine contaminants while providing additional reduction of PFAS, chlorine, chloramine, VOCs, bacteria and viruses. Together, these three technologies provide a more comprehensive filtration solution than a conventional sediment + carbon + carbon whole-house filtration system. Up to 400,000 Litres Filtration Capacity The HydroTech system is designed for long-term whole-house use, with a filtration capacity of up to 400,000 litres under suitable incoming water and operating conditions. The full-size 20" x 4.5" cartridges provide significantly greater filtration media volume and contaminant holding capacity than smaller filtration systems, helping deliver long service intervals while maintaining excellent water flow. High-Flow Whole House Performance Whole-house filtration requires more than effective contaminant reduction — it also needs to maintain sufficient water flow for everyday household use. The HydroTech system uses full-size high-capacity cartridges specifically designed for whole-house applications, allowing filtered water to be supplied to multiple outlets throughout the property. Suitable for: Kitchen • Showers • Baths • Bathroom Taps • Laundry • Appliances This makes the system ideal for households requiring comprehensive filtration without unnecessarily sacrificing everyday water pressure and flow. Full-Size 20" x 4.5" Filter Cartridges The system uses commercial-size 20" x 4.5" filter cartridges, providing substantially more filtration media than standard 10" filtration systems. The larger cartridge format provides: Greater contaminant holding capacity Longer filtration intervals Higher water flow Lower flow restriction Better suitability for whole-house applications Heavy-Duty 304 Stainless Steel Construction The HydroTech system is built for long-term whole-house installation. Both the main structural frame and protective outer cover are manufactured from 304 stainless steel, then finished with a durable powder-coated surface. This construction provides: Excellent structural strength High corrosion resistance Additional environmental protection Premium appearance Long-term durability Technical Specifications Specification Details Filtration Stages 3 Stage Cartridge Size 20" x 4.5" Stage 1 HydroTech MLSF Series Stage 1 Micron Rating 5 Micron Stage 2 HydroTech HFMF Series Stage 2 Micron Rating 0.22 Micron Stage 3 HydroTech EPC Series Electropositive Filter Stage 3 Micron Rating 0.5 Micron Filtration Capacity Up to 400,000 Litres* Maximum Pressure 550 kPa / 80 PSI Maximum Temperature 38°C / 100°F Housing Connections 1" BSP Frame Material 304 Stainless Steel Protective Cover Material 304 Stainless Steel Surface Finish Powder Coated Application Whole House Water Filtration Key Benefits Advanced 3-stage whole-house filtration Up to 400,000 litres filtration capacity 5 micron multi-layer progressive sediment filtration 0.22 micron high-flow multi-function filtration 0.5 micron advanced electropositive filtration Reduces chlorine Reduces chloramine Reduces PFAS Reduces fluoride Reduces heavy metals Reduces VOCs Reduces bacteria and viruses Reduces scale build-up Improves taste and odour Nano silver catalytic filtration technology Full-size 20" x 4.5" high-capacity cartridges Designed for high-flow whole-house applications 304 stainless steel structural frame 304 stainless steel protective cover Durable powder-coated finish A More Advanced Approach to Whole House Water Filtration From visible sediment to extremely fine contaminants, the HydroTech Triple Whole House Water Filtration System uses three complementary filtration technologies to provide comprehensive water treatment before water is distributed throughout your home. The MLSF Series provides progressive sediment protection, the HFMF Series delivers high-capacity multi-function contaminant reduction, and the EPC Series adds advanced electropositive and catalytic filtration as the final treatment stage. The result is a premium whole-house filtration system designed to provide cleaner, better-tasting water throughout your home while maintaining excellent water flow. Important Information Filtration capacity of up to 400,000 litres depends on incoming water quality, contaminant levels, water consumption and operating conditions. Filters may require earlier replacement where incoming water contains elevated sediment or contaminant levels, or where a noticeable reduction in water flow or filtration performance occurs.
