Enjoy fresh, great-tasting water every day with a compact, convenient filtration system installed discreetly beneath your kitchen sink.
Whether you're looking to reduce chlorine taste and odour, improve the clarity of your drinking water or target specific water-quality concerns, under-bench filtration offers a practical way to upgrade the water you drink and cook with.
At WTS, we supply a range of quality under-bench water filters, from simple activated carbon systems to advanced multi-stage filtration and reverse osmosis solutions.
Better water for drinking, cooking, tea and coffee — without cluttering your kitchen.
Why Choose Under-Bench Water Filtration?
Good-quality drinking water should be convenient, enjoyable and readily available. Under-bench filtration improves your everyday water experience without requiring a large or complicated installation.
Unlike jug filters or bottled water, an under-bench system provides filtered water directly from your tap, making it a convenient long-term addition to your home.
Explore Under-Bench Filtration Technologies
Not all water filters work in the same way. Different filtration media are designed to target different substances, and choosing the right combination can make a significant difference to your water quality.
WTS offers filtration solutions for a range of household needs, from everyday taste improvement to more specialised water treatment.
Activated Carbon Filtration — Fresher Taste, Less Odour
Activated carbon is one of the most popular technologies for improving household drinking water. Available in granular activated carbon (GAC) and solid carbon block formats, it uses an extensive porous surface to adsorb chlorine and selected organic compounds that can affect water taste and smell. Key benefits - Reduces chlorine taste and odour. - Improves the everyday drinking-water experience. - Can reduce selected organic chemicals, depending on the cartridge. - Available in compact, economical systems. - Works well as the final polishing cartridge in multi-stage filtration. Ideal for: Town-supply homes, offices and households wanting better-tasting water straight from the tap.
GAC + KDF Filtration — Enhanced, Targeted Treatment
Combining granular activated carbon with KDF media brings together two complementary filtration technologies. KDF uses a copper-zinc medium to reduce certain substances through an electrochemical process, while activated carbon provides additional treatment for taste, odour and selected organic compounds. Key benefits - Combines complementary filtration methods. - Can reduce chlorine and selected dissolved metals. - Supports treatment of specific water-quality concerns. - Provides additional options beyond conventional carbon filtration. - Can be incorporated into multi-stage systems for more comprehensive treatment. Ideal for: Households seeking enhanced chemical or metal reduction where the selected cartridge is rated for the substances of concern.
Multi-Stage Filtration — Multiple Benefits, One System
Multi-stage filtration combines different cartridge technologies to address several water-quality goals within one compact installation. Each stage performs a particular function, allowing the system to progressively treat the water before it reaches your tap. A typical three-stage arrangement may include: 1. Sediment- Particles and debris 2. KDF / Specialty- Targeted treatment 3. Carbon- Final polishing Key benefits - Combines sediment removal with additional treatment functions. - Can address several water-quality concerns in one installation. - Helps protect downstream filtration media from particles. - Uses activated carbon as the final cartridge for taste and odour polishing. - Available in compact systems suitable for many kitchen installations. Ideal for: Households wanting several filtration benefits in a single under-bench system.
Reverse Osmosis — Advanced Drinking-Water Filtration
For households seeking a higher level of treatment for selected dissolved substances, reverse osmosis (RO) offers an advanced filtration solution. RO systems use a semi-permeable membrane to separate water from a wide range of dissolved substances, including salts and certain metals. Key benefits - Significantly reduces total dissolved solids. - Can reduce a broad range of dissolved contaminants. - Provides advanced treatment for specific water-quality requirements. - Offers a dedicated source of highly filtered drinking and cooking water. - Available with additional pre-filtration and final carbon polishing stages. Ideal for: Households with particular dissolved-contaminant concerns or those seeking advanced drinking-water treatment. RO systems require appropriate feed-water conditions and produce a wastewater stream during treatment. WTS can help determine whether reverse osmosis is the right choice for your water.
Filtration performance depends on the selected product, water conditions and maintenance. Where microbial contamination is a concern, an appropriate disinfection system may also be required.
How Does Under-Bench Filtration Work?
Under-bench water filters connect to your cold-water supply and treat the water before delivering it to your kitchen tap.
Depending on the system, water may pass through one cartridge or several stages of filtration.
For a typical multi-stage system, the process is straightforward:
-
Sediment filtration: Captures suspended particles such as sand, silt and rust.
-
Specialty media filtration: Provides targeted treatment using media such as KDF.
-
Activated carbon filtration: The final cartridge improves taste and odour and reduces selected chemicals.
The filtered water is then delivered directly to your chosen tap, ready for everyday use.
Which Under-Bench Filter Is Right for You?
The best filtration system depends on what you want to improve about your water.
If your water comes from a rainwater tank or bore, the correct solution may involve additional treatment beyond a kitchen filter.
WTS can assess your requirements and recommend a suitable approach.
Not sure what your water needs?
Our water-testing service can help identify concerns and guide the selection of an appropriate treatment system.
Installation Options to Suit Your Kitchen
Under-bench filtration can be incorporated into many existing kitchens without major changes.
WTS can help you select the appropriate installation arrangement based on your filter system, available space, water pressure and kitchen layout.
Servicing & Maintaining your Under-Bench Filter
Keep Your Drinking Water Fresh, Clean & Great-Tasting
Regular servicing is essential to keeping your under-bench filtration system performing at its best. Over time, filter cartridges collect sediment, impurities and other contaminants, gradually reducing their effectiveness and potentially restricting water flow.
Replacing your filters at the recommended intervals helps maintain water quality, protect your filtration system and ensure you continue enjoying the benefits of filtered water every day.

Under-Bench Filtration for Mains Water and Rainwater
Mains Water Supply
For households connected to treated town water, under-bench filtration is an excellent way to improve drinking-water taste and reduce chlorine odour.
Carbon filtration is often a practical starting point, with multi-stage systems and other technologies available for additional treatment requirements.
Rainwater and Private Water Supplies
Rainwater and bore water can have different water-quality challenges, including sediment, organic matter, microorganisms or dissolved minerals.
Under-bench filtration can play a valuable role in improving drinking-water quality, particularly when used alongside appropriate whole-house filtration and disinfection.
For properties using private water supplies, WTS can help design an integrated treatment solution that addresses both household water quality and drinking-water requirements.
