If you’re a casual hobbyist who just wants crystal-clear ice cubes, get a standalone DI cartridge. It’s cheap, cheerful, and you’ll feel like a mad scientist every time you fill a beaker.
If you’re an obsessive perfectionist who needs laboratory-grade water every single day without replacing parts every Tuesday, go RO+DI. Your future self will thank you when the resin lasts a year.
Me? I went with the RO+DI integration because I hate changing cartridges. Also, I like drilling holes in things. Don’t judge.
So, which one matches your level of crazy? Either way, you’ll be drinking (or testing) water that’s purer than a monk’s soul. Cheers to that.
