First up, the filter system itself. This is the main character in your water story. A basic sediment and carbon filter system runs about $300 to $800. It catches rust, dirt, and chlorine. Your water will taste better, and your skin will thank you.
Then you get into the fancy territory. Salt-based water softeners? That’s an extra $500 to $1,500. Reverse osmosis for the whole house? Buckle up—that’s often $1,500 to $3,000 just for the hardware. You’re basically buying a mini science lab for your basement.
And don’t forget UV filters. They kill bacteria with light—like a tiny, water-based tanning bed. Those add another $400 to $800. Perfect if you’re on well water and paranoid about creepy-crawlies.
