Every filter is capable of filtering 40 gallons of water and comes with an approximate life span of two months . The filter has been thoughtfully designed, be it the white oak handle to the fridge-friendly size. Every time someone buys a Soma, the team will donate to water projects because they believe that clean drinking water is a basic human right for all. Even the Water Quality Association has tested and certified the Soma filter to NSF/ANSI Standard 42 requirements for the reduction of chlorine, taste and odor. Natural water filtration technique is always worth a buy.
