The first refillable filter cartridge companyWe realised that not everyone was ready to replace their Brita jug with a Phox jug. So we decided to make a product that holds the refillable benefit of Phox but is compatible with Brita Maxtra+ and older Maxtra jugs. This Compatible filter slots into your current jug and is built to last years instead of the standard 30 days. Simply replace the filter granules every 45 days. Less waste, more taste.We are here to provide a solution to an ever increasing single-use plastic problem. In the pursuit of clean and tasty water, millions of filter cartridges go to landfill each year. In 2019 we decided to put an end to that by creating the first refillable filter cartridge. Traditional filters don't fit through the letterbox, that leads to missed deliveries and second attempts which increases the carbon emission of the delivery cycle. As we only have to send the filtration granules, they are designed to fit through the letterbox.. Refillable cartridge built for life..
