Here’s the secret sauce to making your system live to a ripe old age. Change your pre-filters on time. Set a reminder on your phone. If you can’t remember, the filters will get clogged, the water flow will drop, and you’ll start getting salty (and not the good kind).
Sanitize the system once a year. Yeah, it’s a tiny chore—like flossing, but for your water. You can buy a $5 sanitizer kit. It kills bacteria and biofilm that can shorten the membrane’s life. Do it after every filter change, and your RO will thank you with crisp water.

Another trick: don’t let it sit idle. If you go on a two-week vacation, your system might grow a science-fair project in the filters. Flush it when you get back. Better yet, drain the tank and let the system “rest” while you’re sipping piña coladas. A dry system is a happy system.
