Yes, a little. You have to change the pre-filters every six months. Then the membrane every two years. It’s like owning a pet that only drinks water and costs $50 a year.
If you ignore it, the membrane gets clogged with gunk. Then it mopes and produces slow-motion drips. You’ll notice when your glass-filling time goes from 30 seconds to 3 hours.
But the payoff? You can fill a glass and literally hold it up to the light. You’re looking at nothing. And that nothing is perfect.
Why You Should Be Curious
This technology is crazy when you think about it. We’re using physics to outsmart nature at its own game of diffusion. Your faucet is a laboratory.
Every drop of RO water has survived a high-pressure gauntlet. It’s the ultimate survivor. Even bacteria get left behind. (Fun fact: bacteria don’t swim through, but they can grow on the membrane if you’re not careful. So you need a UV light sometimes.)
People with fish tanks love RO water because it prevents algae from partying. People with humidifiers love it because there’s no white dust. It’s the water that politely declines to cause problems.
