Let’s get real about installation. A basic DI system is dead simple—screw it onto a faucet adapter, run the hose, done. You can do it in five minutes while half-asleep.
An RO+DI system? You’ll need to drill a hole for the drain line, mount a tank, run tubing, and maybe add a booster pump if your water pressure stinks. It’s a weekend project, not a coffee break.
But once it’s set up, it runs itself. The RO membrane lasts 2-3 years, and the DI resin only needs swapping every 3-6 months. You’ll feel like a water wizard.
Myth-Busting: Both Get Bacteria
Here’s something they don’t tell you in the ads: both systems can grow bacteria if you don’t use them regularly. Pure water with no minerals? Bacteria love that environment. It’s like a luxury spa for microbes.
So if you go on vacation for two weeks, come back and flush the system for 10 minutes. Or invest in a UV sterilizer. Yes, it’s a whole ecosystem under your sink now. Congratulations.
