Ecolo Blue gives you an alternative to bottled water. EcoloBlue Atmospheric Water Generators extract pure drinking water straight from the humidity in the air. Ecolo Blue makes three different models of water generators. Each model can produce up to around eight gallon of waters a day as long as there is at least 35% humidity in the air. Unlike bottled and delivered water, EcoloBlue water is completely sustainable and costs just $.20-$.45 per gallon.
