Let’s keep it real. RO systems are not sprinters; they are marathon runners. They produce water slowly. You’ll fill a glass in about 30–60 seconds. If you need to fill a pot for pasta, you might want to use the regular tap and wait for the filtered water to top it off.
Also, they produce waste water. For every gallon of clean water, a few gallons go down the drain. It sounds bad, but new systems are getting way more efficient. Think of it as a small price for a gold-medal drinking experience.
And yes, they take up space under your sink. You might have to evict that old bottle of floor wax you never use. It’s a storage purge that’s totally worth it.
