Sustainability
We believe a water filter should solve one problem without creating another. Here's how we're thinking about the full picture — honestly.
Natural clay materials
Our filter element is made from naturally occurring clay minerals — one of the most abundant materials on the planet's surface. Clay requires relatively low-energy processing compared to synthetic polymers, activated carbon from petrochemical sources, or reverse osmosis membranes. It comes from the earth and, at the end of its useful life, can return to it.
A plastic cartridge alternative
Most home water filters rely on disposable plastic cartridges that are replaced every few months and end up in landfill or incineration. Billions of these cartridges are discarded annually. Our clay filter element is designed to be cleaned and reused for an extended period — and when it eventually reaches end of life, it contains no bonded plastics or composite materials that prevent recycling or safe return to the environment.
We are also actively exploring options for the housing vessel. Our ambition is a product that is fully recyclable at end of life, with no permanently bonded dissimilar materials.
No electricity required
Our filter is gravity-fed. Water flows through the clay element by its own weight — no pump, no power cord, no battery. This means zero operating energy and zero carbon emissions during use. It also means the filter works anywhere: on a kitchen counter, at a campsite, or in a setting where electricity is unavailable or unreliable.
A lower-disposable philosophy
We reject the subscription model that treats filters as recurring consumables to be thrown away every month. Our filter element is designed to be scrubbed clean and reused. When it eventually requires replacement — measured in months or years, not weeks — the spent element is inert ceramic, not a plastic composite destined for landfill.
We are also exploring whether spent filter elements can be crushed and reincorporated into new clay bodies, creating a closed-loop material cycle. This is an ambition, not yet a proven capability.
An honest caveat
We are still in the development stage. The sustainability characteristics described on this page represent our design intentions and material choices — not verified lifecycle claims.
A full lifecycle assessment (LCA) requires a mature product, established supply chains, and real-world usage data. We commit to commissioning such an assessment when we have a final product to evaluate, and to publishing the results regardless of whether they flatter us.
In the meantime, we believe the most honest thing we can do is choose materials and methods that we have strong reason to believe are more sustainable than the incumbent alternatives — and be transparent about what remains to be proven.
