Here’s the thing: RO is thirsty. For every gallon of pure water you get, you might send 2–4 gallons down the drain. Sounds wasteful, right? But newer commercial units recover up to 80%. That’s like getting a bonus donut with every coffee.
Counterintuitive bonus: RO systems actually save energy in some businesses. Why? Because you don’t have to truck in bottled water. You make it on-site. Sustainability plus a side of smugness.
One more oddball detail: The membrane is alive-ish. It’s made of polyamide—the same stuff in bulletproof vests. Your water filter is basically wearing body armor.
Should You Worry About “Dead” Water?
Some wellness gurus claim RO water is “dead.” They say it has no minerals. Let me translate: It has no minerals, exactly as intended. Your diet is where you get minerals, not from your plumbing. Don’t let a yoga influencer scare you.
But here’s a playful twist: If you really miss your minerals, install a remineralization cartridge. It adds calcium and magnesium back in. It’s like buying a shirt, cutting the sleeves off, then sewing them back on for fashion. You do you.
