Go green and save money by investing in one of these simple yet brilliant bottles. The Water Bobble’s cap contains a carbon filter, which removes all the chlorine and organic compounds found in tap water, giving you a drink that tastes great. Many plastic water bottles end up at landfill sites. The Bobble is made from recycled plastic and the filter lasts three months or 300 uses before it needs changing – producing 150 litres of filtered water.
