The Dolphin will produce 20 liters (a little over five gallons, for those who don't speak metric) of water per day at 70% humidity, which is enough for your office if you go through one of those ungainly water cooler jugs per day or less plus, without the plastic waste, and avoiding other associated costs of water jug transportation (emissions, namely).
