Founded in 2020 by Charles Robinson, Water2 is a fast-growing home water filtration brand. Based in London, Charles launched the company after leaving university and worked with professors to improve tap water quality and reduce reliance on single-use plastic bottles. His goal was to create a simple system that made ‘cleaner, better-tasting water available straight from the tap’. Bear Grylls first became an investor in the business in 2024 after buying a Water2 filter for his own home. Now in over 200,000 homes, their drinking and showerhead filters work to filter out microplastics, fluoride, chlorine and other elements.
