We’ve written about the lovely glass carafe and sustainable water filter designed by San Francisco-based Soma in a previous post, but it’s worth noting their current collaboration with Charity: Water, the non-profit group which has made clean drinking water for everyone its goal. Soma has launched this limited edition yellow filter to help raise funds for Charity: Water’s initiatives in Cambodia. For each Soma carafe and limited edition filter purchased, Soma will donate $12.50 towards providing clean water to every family in 3 Cambodian villages. If you weren’t tempted to buy a Soma water filtering system before, we hope you will be now. The new limited edition filter (and glass carafe) can be purchased here.
