Minus is a fully circular tap water filter that fits in your pocket. It uses pressure from the tap to push water through an all-natural charcoal filter that removes chemicals, bacteria and odour, providing the user with instant access to clean drinking water. Natural indigo colourant acts as an end-of-life indicator. It washes out with use to let the user know when it is time for a replacement, eliminating guesswork. The used filter can be dropped off at any post box to be sent to the factory, cleaned, recharged and sold again to be reused, making for a complete zero-waste experience.
