Someone dropped a leaflet for one of these RainCloud C-15 Water Generators into my postbox last week, which piqued my interest. The machine is a desktop de-humidifier with an integrated water purification system, at a home user price of £719.90. Room air is sucked in via a fan, the water extracted and then run through a series of ultra-fine filters and a final Ultraviolet bug zapper and then served to you just like a conventional water filter device. It holds 20 litres. More here.
Price of RainCloud C-15 equals the price of bottled water usage for 20 months. By keep using bottled water You will continue to pay same price, year after year. Switching on to RainCloud C-15 you could start saving £327.00 a year.
