Now we’re talking. Under-sink systems are the real workhorses. They hide away, they look clean, and they filter a ton of stuff. You get a dedicated faucet that looks fancy. Prices range from $60 to $300 for a decent one.
Installation? You can do it yourself if you’re handy. Or you can pay a plumber, maybe $50 to $150 extra. The filters themselves last six months to a year. Replacement packs cost $30 to $80 per year. So your first year might be $200 to $450 total. That’s a dinner date with your bank account.
Filtration System
Wait, what about the expensive ones?
Oh, we’re about to go off the rails. Reverse osmosis (RO) systems start at $150 and can hit $600. These things strip everything. Minerals, lead, fluoride—they’re like a vacuum for your water. But they waste a lot of water. Like, three gallons of waste for every one gallon of clean. Your water bill might nudge up.
Then there’s the whole-house filter. That’s the $600 to $2,000 range. It sits where your main water line enters the house. It filters water for every tap, shower, and toilet. Yes, even your toilet gets fancy water. Installation is no joke—you’re looking at another $300 to $500 for a plumber.
And finally, the luxury tier. This is where prices laugh at you. Water softeners? $600 to $4,000. Commercial-grade RO systems for the whole house? $5,000 to $15,000. At this point, your water is made of diamonds. It’s basically a spa in your basement.
