Water brings along with it a number of very dangerous water borne diseases, especially in remote, underdeveloped areas. To get around this problem, an Irish company called Aqua-Nu has developed the PURITYCAPSULE water filtration system. The PURITYCAPSULE comes in the form of a filter that can be fitted onto most bottles. The filters contain anti-bacterial coatings and activated carbon to purify water. These filters which can purify different quantities of water come in small sizes which makes them inherently portable. To make the PURITYCAPSULE more eco-friendly, Aqua-Nu has made it with plenty of recylable materials and also have a policy of recycling the filter after it has been fully used. All these factors in conjunction make the PURITYCAPSULE a very effective water purifying device, especially for trekkers and people in underdeveloped countries.
