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.

    Wonderful water

    I initially purchased a waters filter because I searched fir a few years for a good filter, one that could take out fluorine especially. There are many types of water filters and I’ve had a few, but I looked on line and found only 2 brands, and the bio waters was the best one. I went to their shop in Wellington and met Phil the owner of the business. Because of his passion for pure water and sincerity, I was really impressed. He also told me that the filter I came to replace which supposedly takes out fluoride, dies take out some, but uses an aluminum filter which gives you another type of poisoning. So that was it for me , I purchased the bio waters and my family are very happy after 3 years. Recently bi purchased another one for my son’s home in Melbourne.

    Cover up

    I have attempted quite a few times to purchase a cover, they either go quick or there is a big demand. Whilst it is great I do believe it’s quite overpriced in terms of bang for your buck

    Hi Tracey,

    They are definitely overpriced, however this is due to our ex supplier raising the price on us without notice and we have sold them at almost cost price. We are looking for a new supplier to produce these in the future at a more reasonable cost.

    Regards,
    Scott

    Love it!

    So happy with the wrap for my waterfilter. There isn't a spot in the kitchen that doesn't get direct sunlight at some point of the day. Having this wrap now prevents the ceramic insert turning green.

    Great UV cover

    This cover fits perfectly and does exactly what’s it’s supposed to do. The thing I find annoying is the Velcro join is around the back. It would be more convenient if the join was around the front as that is the only way of checking the water level. Or perhaps a flap at the front to check the water level??
