Medical devices are intimate—they go inside people. That means any leftover minerals or bacteria in your water are a giant no-no. DI water strips away the nasty ions, leaving you with the purest H₂O on the planet.
Think of it as a spa treatment for your manufacturing process. Your devices get a squeaky-clean rinse, and your quality audits become a breeze. Plus, you get to sound super smart when you talk about “resistivity” at parties. (Okay, maybe not parties, but definitely at industry conferences.)
