321 water is a reusable water bottle that filters tap water using a unique carbon filter and plunger system to remove chemicals and bacteria, making the water clean. Its slogan "pure by design" suggests the bottle provides pure water through thoughtful design. The bottle's name, 321 Water, refers to the 3 to 1 ratio of water needed to produce one liter of bottled water, hoping to raise awareness of bottled water's environmental damage and encourage people to use the reusable, filtered bottle instead.
