Reverse Osmosis Filter Replacement Scheduleの要点や背景を専門的かつ分かりやすくまとめました。全体像を一目で把握できます。

Pre-filters: every 6–12 months. Membrane: every 2–3 years. Post-filter: every year. And when in doubt, buy a TDS meter—it’s a $10 gadget that tells you exactly how much gunk your membrane is missing. If the number jumps above 50, your membrane is toast.

So go ahead. Mark your calendar. High-five your faucet. Your RO system will reward you with water so pure, it’s basically a hug in a glass. Just don’t forget to swap those filters—your future self (and your mouth) will thank you.
