It wastes water. A lot of it. For every gallon of pure water, the system might send two to four gallons down the drain. It’s like a diva who throws away perfectly good backup dancers.
How Do Water Filters Work? Types & Benefits Explained
Some modern systems are much better. They are trying to be less wasteful. But it’s still a little thirsty.
Also, it’s slow. Very slow. You can’t just blast five gallons in a minute like a garden hose. It trickles. Good things come to those who wait. Or, you just install a storage tank so you never notice.

Ah, here’s the kicker. RO water is so pure it removes minerals like calcium and magnesium. You know, the “healthy” stuff. Your water becomes a bit of a blank canvas.
