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.

    Tip - Wait till they are on sale

    I love my BioMax filter. have had it a couple of years now.

    I like to drink nano/micro plastic and free of chemicals and heavy metals water.

    So you need to ensure you change the filters at the 6 month intervals.

    So I write the changed date on the filters with a permanent marker...then set a Google Calendar reminder.

    Then I go looking if the replacement filter set are on sale.

    If they aren't on sale I usually keep a check out for a few months until they are.

    At any one time I usually have two sets of replacements on hand so it's not critical that I buy when the time is exact...i just buy a set for my spares when a sale is on.

    It would be really nice if Waters Co would have a members rate to buy the filters at equal to any sale price so I didn't have to play this "waiting for a sale game" or give you a non expiring discount code to use for next purchase. If they have a members login page for loyal customers...who knows we might even shout a family member a kit for their water needs.

    Pure water, but quite the delay!

    Filter is great and provides us with clear and clean water vs. tap water. Just make sure you order in good time, there's been shortages and took over 6 months to receive the product - but glad it finally arrived
