Triple Undersink Water Filter System (GT1-38TF)

This Triple Undersink Water Filter System is built for superior sediment removal and high-quality chlorine and odour reduction — perfect for households on mains or rainwater supply seeking a step up from standard 2-stage systems.

The filtration train starts with a 5 micron pleated washable sediment filter, followed by a 5 micron polyspun depth filter, and finishes with a 0.5 micron premium coconut carbon block. This configuration delivers both coarse and fine particle removal, extending the life of the final carbon stage and ensuring consistently clean, fresh-tasting drinking water.

Each component is assembled on a white powder-coated steel bracket with WaterMark Certified housings, 1/4" push-fit ports, and a full fitting kit that includes a modern chrome faucet, 350 kPa Pressure Limiting Valve, and Leak Shut-Off Valve. The system is suited for water supplies with higher sediment loads or customers wanting the extra confidence of a triple-stage design.

Filter 1: 5 Micron Pleated Sediment Cartridge

This washable pleated filter traps larger sediment and debris such as dirt, rust, and silt. With high surface area and low pressure drop, it acts as the first line of defence — ideal for homes with visible particles in the water or when dealing with older plumbing or roof-fed tanks.

Filter 2: 5 Micron Polyspun Depth Filter

The second stage uses a true depth polyspun filter to catch smaller suspended solids not removed by the pleated cartridge. Its multi-layered melt-blown structure allows for effective particulate removal while maintaining a smooth flow.

Filter 3: 0.5 Micron Premium Coconut Carbon Block

Made from 100% coconut shell carbon, this high-performance carbon filter adsorbs chlorine, taste, odour, and a wide range of chemical by-products. Its ultra-fine 0.5 micron rating also helps remove fine particulate matter and polishing the water for drinking and cooking.

Manufactured under the High Performance Filtration (HPF) line, this cartridge delivers excellent flow with minimal pressure loss and is suitable for long-lasting chemical protection.
