Haven’t completed our Water Quiz yet?
We recommend doing so before making your purchase. The quiz helps you choose the ideal PreFilter setup for your specific water source and needs, ensuring the best results for you and your family.

Our standard tank filter set includes an Ultra Filter (0.01 µm) and our Carbon Ultimate Filter. To maintain peak performance, remember to rinse the Ultrafilter regularly. For best results, install a 5-micron filter after the pump to prevent dirt and sediment from clogging the ultrafilter.

See below for more details on the key features and specifications of our tank water filters.

Additional Notes:

Contaminants removal data is based on manufacture specs, testing or information gathered.


  • Carbon Ultimate Filter is designed to last up to 6000L. The Carbon Ultimate Filter must have a sediment filter before it if your source water is known to contain lots of sediment otherwise they will get clogged up and have reduced flow and function.
  • Ultrafiltration depending on source water will require rinsing after a certain time frame such as 3 months.
  • Inline Ultrafiltration needs to be replaced after 3 months or sooner depending on source water.
  • Tank and Bore water should ideally have an additional 5 micron filter to capture sediment between the tank and the house otherwise the ultrafilter will be so full or sediment it will slow the flow right down.
  • A 5-micron filter removes dirt, rust, sand, and other visible debris to help protect the ultrafilter, improve flow, and extend system life. We recommend you get one locally, online or from your plumber. They are cheap and only do the job of removing sediment. We prefer the 5 micron poly pleated filters that can be washed.

Do you ever worry about the quality of the water you and your family are drinking?


Many households on tank water are unknowingly exposed to bacteria, viruses, and parasites such as E. coli, Giardia, and Cryptosporidium, which can cause gastrointestinal illnesses, diarrhoea, and other infections. During warmer months, tank water may be susceptible to algal blooms, especially if exposed to sunlight and nutrient runoff. River water can also be contaminated with bacteria, viruses, and parasites from various sources, including agricultural runoff, sewage discharge, and wildlife faeces. Consumption of untreated river water can result in gastrointestinal illnesses, infections, and waterborne diseases.

Our hand-crafted filter inserts are compatible with our below and above-sink / countertop water filter system to help eliminate these worries by providing you with pure, clean, and great-tasting water.


With our advanced filtration technology, every glass of water becomes a step towards better health, improving your well-being and peace of mind. Don’t compromise on your health — transform your tap water into a fountain of vitality with our trusted water filters.


Key Features of Our Water Filters:
Effective Filtration:

Transform your water’s taste and purity with our advanced filtration system. The first filter features a 5-micron washable pleated sediment filter that removes dirt, rust, algae, turbidity, and other particulate contaminants. The powerful second filter, a 0.01 µm ultrafilter, removes pathogens down to 0.01 µm. The final filter combines KDF55, catalytic carbon, and mineral-enhancing, pH-balancing materials to eliminate or neutralize harmful substances like chlorine, chloramine, trihalomethanes (THMs), pesticides, herbicides, VOCs, pharmaceutical chemicals, and heavy metals. It also retains essential minerals like calcium, potassium, and magnesium, improving taste and offering health benefits.


Health Benefits:

Tank water may contain harmful chemicals like pesticides, herbicides, and heavy metals from agricultural runoff, industrial pollution, and atmospheric deposition. These contaminants can pose long-term health risks, including cancer, neurological disorders, and reproductive issues. A UV system can also be added for ultimate protection, ensuring your water is free from these threats and supporting your overall health.


Versatile Usage:

Our filters provide more than just great-tasting drinking water. They’re perfect for washing produce, cooking, making beverages, filling pets' water bowls, and even watering plants. With mineral-enhanced, pH-balanced water, staying healthy and hydrated becomes simple, enhancing your daily routine.


Importance for Water Ionizers:

Our system is designed to reduce contaminants for up to 6000L and is optimized for Kangen water ionizers. It helps reduce contaminants, correct acidic water, add minerals, and control water hardness—key for maximizing the ionizer’s electrolysis process. Clean, mineral-rich water improves ionization and prevents scale buildup, enhancing both the health benefits and lifespan of your ionizer.


Convenience and Portability:

Easy Installation: Our Australian Watermark Twin Under Sink System fits compactly under your sink, with a tapered filter tap for easy Kangen water hose attachment. It requires a bench with a ~10mm hole for installation or an optional dual main tap upgrade.


Durable Materials: The system uses BPA/BPS-free food-grade plastic or 304 stainless steel and features compression fittings to prevent leaks.


Economical and Eco-Friendly:

Cost-Effective: Enjoy purified water at under 8c per litre—far cheaper than bottled water. Save money, reduce plastic waste, and avoid drinking microplastics from bottled water.


Local Assembly: Proudly assembled locally with high-quality parts, ensuring reliability and performance. Each filter cartridge is handcrafted with care for superior water purity.


Peace of Mind: Comes with a 12-month warranty. To maintain warranty coverage, ensure regular filter changes using our replacement parts.
