Supplemental Renal System
Renal failures have taken too many lives, especially after the legalization of most hallucinogen substances years ago. To aid the low-willpower-high-stress-corporates of our society Saedor Krupp devised the Supplemental Renal System. The system is a pair of highly effective toxin filtration units connected to both of the user's kidneys or completely replacing them.
Because the system is so effective, it purifies much more of the bodies water supply effectively halving the user's need for water intake. As you can imagine, this cyberware is popular among most desert explorers.
