The Waters BioMax 4-stage under sink water filter system delivers high-quality drinking water directly from your tap, without taking up valuable bench space. Designed for homes where space is limited and water quality matters, BioMax provides clean, great-tasting alkaline mineral water at the point of use.

Developed over more than two years to closely replicate the performance of Waters Co benchtop systems, BioMax reduces unwanted taste and odour while targeting common tap-water contaminants. The system operates without electricity and delivers a steady flow rate of approximately 0.75 litres per minute, making it ideal for everyday drinking and food preparation.

Please note, the tap/faucet is not included and must be selected separately to suit your kitchen setup/design needs.

FAQs

Waters Co filters go beyond simple contaminant removal. Using multi-stage technology, including ceramics, activated carbon, bio-ceramics, magnets, and coral, they not only purify but also remineralise and alkalise water. This creates “living water” that hydrates more effectively than standard filtered water.

Yes. Independent laboratory testing shows Waters Co filters remove up to 99% of fluoride, as well as heavy metals such as lead, mercury, and cadmium. They also reduce chlorine, pesticides, industrial chemicals, and microplastics.

No. Unlike reverse-osmosis systems that remove everything, Waters Co filters preserve and reintroduce beneficial trace minerals. The result is water that not only tastes better but also supports bone health, pH balance, and hydration at the cellular level.

Waters Co filters are designed for longevity. Depending on the system, filters can last up to 4 years with average household use. This means far fewer replacements than most pitcher or countertop brands, saving money and reducing waste.

Yes. Waters Co holds certifications from NSF International, ISO, CE, FDA, and the Water Quality Association, among others. They’ve also won global awards for quality and environmental stewardship, ensuring proven performance and trust.

Absolutely. Customers consistently report cleaner, fresher, and smoother-tasting water. By removing chlorine, pesticides, and organic contaminants, and adding back minerals, Waters Co water often tastes like natural spring water.

Waters Co filters are eco-friendly. With long filter life and BPA-free designs, they reduce plastic waste from bottled water and require fewer cartridge changes compared to other brands. They’re also non-electric, using natural processes instead of power.

No. When you calculate filter life, Waters Co water costs as little as 3 cents per litre, far cheaper than bottled water and many competing filtration systems that require frequent cartridge replacements.

Yes. Waters Co offers a range of portable options, including bottles and jugs, perfect for travel, work, or the gym. This makes it easy to enjoy clean, mineral-rich water anywhere.

Yes. By removing harmful toxins and enriching water with natural minerals, Waters Co supports better hydration, gut health, immune function, and overall wellbeing. Studies show that clean, mineral-balanced water is linked to lower risks of gastrointestinal illness and certain cancers.

    Healthy Water Made Easy

    Knowing our water is filtered and minerals are not missing is incredibly important to us. Our Waters BioMax was easy to install and the price was fair. Can you really put a price on great tasting water? Quick delivery.

    BioMax helped us turn our acidic rain water into healthy drinking water

    Installed the BioMax undersink about 3 months ago. Despite initially leaving a somewhat chalky taste (quite probably from the calcite filter working overtime with our highly acidic rain water - PH5.3), the filter now provides us with clean, pure water for drinking and cooking. Living off-grid and relying entirely on rainwater for our farm homestead - the BioMax has helped us turn our health around.
