Your tap water isn't as clean as you think

The S6 offers a cost-effective solution for your family.

Standard water filters struggle to remove microplastics, some heavy metals, chlorine and fluoride – all which can be found in our tap water and are linked to long-term impacts on hormonal health and fertility.*

Meet the S6 - our flagship water filtration system

Four-stage reverse osmosis filtration with natural remineralisation. No plumbing. No installation. Just clean, balanced drinking water from your benchtop.

Why The Clean Water Co

We built what we couldn't find on the market

A water filter that does the full job — removes the bad and adds back the good.

Removes what others can't

Most water filters don't remove fluoride or heavy metals. Our RO membrane filters to 0.0001 microns — one of the most thorough methods available.

Adds back what you need

Pure RO water is clean but stripped bare. We remineralise every litre with calcium, magnesium, potassium, and more — closer to natural mineral water.

No plumbing required

No installation. No plumber. The S6 sits on your benchtop and goes with you when you move house.

NZ-owned and operated

Founded in New Zealand, built for New Zealand homes. Local support and a 2-year manufacturer's warranty.

Why we started

The Clean Water Co was founded by a Kiwi who got curious about what's actually in our tap water. After getting our tap water independently tested by Hills Laboratories, the results made us look harder at what was on the market - and what we found didn't go far enough. So we built our own - taking years of research and working directly with manufacturers, to get better water for our families.
