Dollar and cents

Unlike our competitors when you purchase our filter systems they come complete with all the options and replacement parts you need to keep you going for years to come, so there's nothing more for you to buy or spend on to upgrade. Most other systems that appear to be cheaper to buy will actually cost more than double than the investment made in a Waters Co system in ongoing maintenance.

The Bio 400 comes complete with a filter kit & replacement componants to last up to 12,000 litres*. Based on 8 litres per day that works out to around 4 years.

  • The Bio 400 works out to $140 per annum or around 3 cents per litre (based on 3 year filter kit included)
  • Similar brands are up to $250 per annum or around 6 cents per litre (Only include filters for 6-12 months when new)

Natural alkaline mineral water

Our research team include World Peace Prize winning genetic scientists that weren't just satisfied with providing the best filtration. They research down to DNA levels to ensure that you get the best water for optimum hydration and cellular support to give you the best potential for health & longevity.

BIO stands for Bio Mineral Pot, adding over 60 bio organic minerals including calcium, magnesuim and all important silica. Derived from coral and silica sands, instead of inorganic minerals from rock and artificially coated alkalising stones or electronic alkalising ioniser machines.

Ideally drinking water should be close to our bloods natural pH of around 7.36 our filters systems and the minerals added are mildly alkalising to the body and our filtered water typically has a pH of around 7.6 - 8.2

The 60 plus minerals added are critical to our body's cellular health, functioning of vital organs and muscles.

Eco friendly alternative to bottled water

Store-bought bottled water isn’t just expensive. It contributes to the consumption of tonnes of environmentally un-friendly plastic waste made from non-renewable fossil fuel resources

When these bottles are emptied, the greater percentage become landfill - or garbage that ends up in waterways and oceans threatening marine life & much more.

Greenhouse gases are the by-products of manufacturing these disposable, store-bought plastic water bottles & many of the reusable bottles which still have a limited lifespan, so to are the carbon emissions from vehicles that transport these bottles to shops.

With the Bench top filters you can fill a water bottle at home before leaving for the day or consider a Waterman portable filter, which makes it easy to drink fresh alkaline water anywhere – without wasting your money or the planet’s resources in the process.

Activated water

Waters Co Mineral Pots feature Far Infrared Ceramics, which are made from a mixture of various metals and non-metal elements that have been treated at a temperature of between 900º-1300ºC. In the resulting ceramic, Ki (Chi or life energy) is generated, which is absorbed and stored in water. Drinking water is thus synonymous to drinking Ki.

Summary of the effects of far infra-red ray:

  • Production of Ki (Chi or life energy)
  • Increase in physiological activity
  • Regulates Perspiration
  • Relieves pain
  • Removes heavy metals from cells
  • Helps sleep
  • Effective deodorization (Bacteriostatic)
  • Suppress germ growth
  • De-humidifying property
  • Air purification
  • Slightly alkalising

Negative ion (Anion) water

Far infrared also creates negative ions (anions) that are hugely beneficial to our health & wellbeing. There are more than 1500-2000 particle anions/cm3 (Negative Ions) in the WATERS Bio Mineral Pot water purifier systems.

There are lots of anions in the air found in forests, around waterfalls, in grasslands, water fountains/features and at the beach. When people come into contact with these sorts of environments, they feel refreshed. There are stones in the mountains that generate many anions. In cells, anions combine ions with active acids, which reduces the generation of toxic active acids.

Benefits of Negative ions (anion) to the human body

  • Strengthens the immune system.
  • Anions vitalise cells in the whole body and increase the immunoglobulin that strengthens the immune system.
  • Provides oxygen to cells
  • Anions act upon the cell membrane, and provide nutrients and oxygen to the cells, discharging carbon dioxide and other wastes.
  • Blood Purification
  • Healthy blood has pH of approximately 7.4. Anions change acidic blood to the basic level that is found in a healthy person's body.
  • Helps recovery from fatigue
  • When anions are absorbed into the body, the body fluid vitalises the body’s metabolism, resulting in the decomposition of fatigue-causing substances that are accumulated in the body. This helps us to recover from fatigue.
  • Stabilises the autonomic nerve system
  • Autonomic nerves govern the body’s organs. The nerves that vitalise organ activity are known as sympathetic nerves, and the nerves that suppress organ activities are parasympathetic nerves. Anions act upon these autonomic nerves and stabilize their activities.
  • Improves the allergic conditions
  • It is verified that anions are beneficial treatment for allergies of the respiratory system. Anions affect the autonomic nerves that strengthen against allergies and improve the physical constitution, hence the popularity of air ionisers & salt crystal lamps.

Magnetised structured micro cluster water

Magnetised water's biological effects:

  • Promotes growth, fitness and metabolism
  • Strengthens the resistance of the living body due to its high activation in the body.
  • Helps with digestion and the helps bowel activities.
  • Prevents or treats gallstones and urolith (Urinary tract stones) generation.
  • Helps to discharge bodily waste and increases liver function.
  • Maintains the tears, sweat, saliva, and the intestinal fluid.
  • Suppresses germ growth.
  • Solubility, cohesion, and conductivity are increased.
  • Maintains longer cohesion.
  • Magnetised water does not evaporate easily.
  • Due to its molecular structure being densely crowded, it is slow to freeze and slow to melt.
  • Due to its particular molecular structure, concentrated water colonies are formed.
  • Cancer preventative. Water treated at the N Pole creates a higher ratio of hexagonal water. Therefore, there are studies that claim it suppresses the growth of cancer cells.
  • Create more hexagonal micro-clustered water.

Frequently Asked Questions

What makes Waters Co filters different from other water filters?

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.

Do Waters Co filters remove fluoride and heavy metals?

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.

Will the filter strip out essential minerals like calcium and magnesium?

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.

How long do the filters last?

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.

Are Waters Co filters certified or tested?

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.

Do Waters Co filters improve the taste of water?

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.

What is the environmental impact of using a Waters Co filter?

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.

Are Waters Co systems expensive to maintain?

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.

Can I take a Waters Co filter with me on the go?

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.

Is the water really “better for my health”?

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.

    The best tasting water

    Our tap water is absolutely atrocious. The smell of chlorine is overwhelming. I bought the Waters filter for our family of 3 after much deliberation.

    And we cannot be happier. Our water has no smell and no chemical aftertaste. Just clean and fresh tasting water. Even my sourdough starter is happily accepting it and thriving. Before I had to use bottled water. I’m confident I’ve done my best by purchasing this filter. Thank you Waters, one very happy water drinking family

    Finally found the perfect filtered water solution

    We’ve spent years and hundreds of dollars buying Pureau filtered water boxes from the supermarket, so it was time to find a more sustainable long-term solution. After some research, we chose the BIO 400 5.25 Litre and are really pleased with the decision.

    We ordered during the mid-year sale and were impressed by the fast delivery and the clear written and video instructions. Installation was simple and straightforward.

    The peace of mind of not having to drink heavy metals, fluoride, bacteria and microplastics is unparalleled. The taste of the water is noticeably better, smooth, clean and free of any chlorine smell or aftertaste.

    The 5.25 litre capacity is ideal for our family. It fits neatly on the benchtop without taking up much space and holds enough water to avoid frequent refills. This has been a great investment in both health and convenience.

    Benchtop filter

    I love my 5.25 litre benchtop filter.

    I have been using my portable Waters filter for many years and decided it was time to get one that would last me all day without multiple refills.

    A Game Changer!

    We saved and saved for a benchtop water filter and hoped we were making a good choice-turns out it is THE BEST! My tummy loves the fresh filtered water! The water from the kitchen tap SMELLS different, but by the time it goes through the benchtop WaterCo filtration system it’s pure- it’s completely insane how different it is! Easy to put together with excellent instructions. Fabulous customer service with prompt email reply (when i enquired about best practice when we move house). Couldn’t recommend this unit and this company more!

    Completely worth the investment!

    Tastes the way water should.

    Great size for one person. I prefer my water cold and it’s so easy to fill up several bottles to keep in the fridge. You know it’s excellent when there’s no taste or smell, just pure hydration. I saved for a while and it’s so worth it. Very happy.
