Product Description

20" x 4.5" Whole House Water Filter Replacement Cartridge Set

Complete 3-Stage Advanced Filtration Set

This complete 20" x 4.5" whole house replacement cartridge set includes three specialised filtration cartridges — MLSF Series, HFMF Series and EPC Series — engineered to work together as a complete high-performance whole-house filtration solution.

Combining progressive sediment filtration, high-flow multi-function filtration and advanced electropositive filtration, the system provides broad contaminant reduction while maintaining the high flow required for whole-house applications.

The three-stage combination targets sediment, chlorine, chloramine, PFOA, PFOS, fluoride, heavy metals, VOCs, cysts, bacteria, viruses and scale build-up, while improving water taste and odour.

3-Stage Advanced Filtration

Stage 1 – MLSF Series Progressive Sediment Protection

The MLSF Series provides the first stage of filtration through a multi-layer progressive filtration structure.

It captures dirt, rust, sand, silt, algae and other suspended particles, helping protect the advanced filtration stages that follow and maintain overall system performance.

Stage 2 – HFMF Series High-Flow Multi-Function Filtration

The HFMF Series combines advanced contaminant reduction with the high flow required for whole-house applications.

It targets chlorine, cysts, fluoride, VOCs, heavy metals and scale build-up, providing broad water treatment without unnecessarily restricting household water flow.

Stage 3 – EPC Series Advanced Electropositive Filtration

The EPC Series is an advanced final-stage cartridge combining electropositive filtration media with nano silver catalytic sintered activated carbon.

Unlike conventional silver carbon filters, where silver is primarily used to help inhibit bacterial growth within the filter media, the EPC Series is designed to go significantly further.

Its electropositive filtration technology actively captures and removes bacteria and viruses from the water, rather than simply helping suppress bacterial growth inside the cartridge.

The specialised nano silver catalytic sintered activated carbon provides additional reduction of chlorine, chloramine, PFOA, PFOS and VOCs, while also improving taste and odour.

This combination of electropositive filtration and advanced catalytic carbon technology provides a significantly broader level of treatment than conventional silver-impregnated activated carbon cartridges.

More Than Conventional Silver Carbon

Many conventional silver carbon cartridges use silver primarily for its bacteriostatic properties, helping inhibit bacterial growth within the carbon media.

The EPC Series is different.

Its advanced electropositive media is specifically designed to capture and remove bacteria and viruses from the water, providing an additional physical filtration barrier against microbiological contaminants.

Combined with nano silver catalytic sintered activated carbon, the EPC Series delivers advanced treatment for both microbiological and chemical contaminants in a single high-performance cartridge.
