Better-tasting tap water – Thanks to granule-based softening and filtration

Filter granules capture contaminants while adjusting water hardness to reduce chalky mouthfeel, and carbon felt discs help trap particles during refills. The granule sachets are designed for 45-day cycles to maintain filtration performance over time.

Softer-feeling water with reduced chalkiness makes drinks and boiled water taste cleaner. Regular sachet changes keep the filtration consistent without complicated parts.

Lower plastic waste – With a refillable cartridge system

A refillable cartridge was developed to replace single-use cartridges, allowing filter granules to be topped up rather than discarding an entire plastic cartridge. The refill pack supplies granules and carbon discs so replacements occur without new plastic housings.

Significantly less household plastic waste compared with disposable cartridges over repeated refills. Refill cycles make sustainable sourcing practical for regular users.

Simple maintenance – With two 45-day sachets and carbon felt discs

The pack contains two 45-day sachets and two carbon felt discs with full setup instructions included. The refill routine involves disposing of used granules and pouring in fresh granules, while the Phox app helps track when to replace them.

Quick, low-mess swaps that do not require special tools, and app reminders reduce the chance of missed changes. An easy routine keeps the water tasting consistent with minimal fuss.
