In the pursuit of clean, great-tasting water, millions of disposable filter cartridges end up in landfill every year. At Phox, we set out to change that with the world’s first refillable water filter cartridge - a UK-made, sustainable alternative designed to reduce plastic waste without compromising on performance. Tested for proven filtration you can trust, it’s built for cleaner, better-tasting water and a lighter impact on the planet. Just refill with fresh granules every 45 days or 200 litres, and keep the cycle going.
