The 'Sustainable Filtration Kit' is a new product that helps people build their own DIY water filters from local materials. The new kit is designed to provide an affordable solution for purifying polluted water from local sources. For countries without a reliable source of filtered water, this kit could be a life-saving solution.

In order to use the Sustainable Filtration Kit, all you need is a piece of scrap wood for the carbon and a plastic bottle that can act as the water filter. The kit comes with a container that you fill with wood and heat over an open fire. Once the container cools, the carbon can be crushed into a fine powder and added to the provided filter. The use of oxygen to cook the wood helps to produce a high purity carbon that is similar to that found in most household water filters. Because the DIY water filters do not use any additional chemicals, it is a cheaper and more accessible option for the vast majority of people to use.
