So, how much? For a decent under-sink setup with installation and first-year filters? Expect $350 to $700. For whole-house? You’re looking at $2,000 to $5,500, easy.
Now here’s the funny part: is it worth it? If your tap water tastes like a swimming pool, yes. If you live in Flint, Michigan, definitely yes. If your water is already great, you just bought a very expensive plastic ornament.
A Quirky Final Thought
Reverse osmosis water is so pure, it can leach minerals from your pipes. Old homes? That pure water might dissolve lead from soldered joints. You buy a system to remove lead, but it makes the water more aggressive. Irony tastes delicious.
Also, the water is so clean, plants hate it. They need the minerals. So your RO water is for you, not your ficus. The ficus gets tap water. It’s a social hierarchy in your kitchen.
