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.

    Best Decision Ever!

    I recently bought this water filter for my kitchen bench, and it’s been amazing! It was super easy to set up and fits perfectly without taking up too much space. The water tastes so much better now—clean, fresh, and way better than tap water.

    I also love how simple it is to use, and the filters are easy to change. It works quickly too, so I’m never waiting long for clean water. The design is nice and feels sturdy, which gives me confidence that it’ll last a long time.

    This filter has made such a big difference for me, from drinking water to cooking. I’m so happy with it and would definitely recommend it to anyone looking for a reliable, easy-to-use water filter. Five stars for sure!

    Delighted with my recent purchase, nice and easy to put together and now sits proudly and prominent on my kitchen bench top! Water tastes amazing, just knowing that you are putting the best clean chemical free water into my body is such a great feeling. Highly recommended for ease of use and the cost effectiveness is bang for buck.

    A worthy investment!

    Clean tasting water with a filter that needs no replacing for many years. My only regret is that I didn’t buy the biggest one! Also, the customer service is amazing. I think it’s 24/7?? They reply to me even when it’s late at night and I’ve always resolved my queries thanks to their fast response. Highly recommend!

    I recently purchased the BIO 400. MAX Grey 7L Bench Top Water Filter. I am really enjoying this water filter. Only downside is the water tap can be a bit slow and fiddly.
