So, does reverse osmosis waste water? Technically, yes. But does it “waste” it in a way that should keep you up at night? Not really. It’s a trade-off. You trade a few gallons of water for incredibly pure, delicious, bottle-free hydration.
It’s like asking if your lawnmower “wastes” gas. It does, but you’re using it for a purpose. You wouldn’t mow your lawn with scissors to save fuel, right? Same logic applies here. Don’t let the perfect be the enemy of the good—and good water is delicious, healthy, and easy.
So go ahead, fill that glass. The water is crisp, the planet is fine, and your fern is thriving. That’s a win-win-win in my book.
