If you want to go from “tap mystery” to “pristine spring,” a reverse osmosis (RO) system is your best friend. It forces water through a semi-permeable membrane that blocks up to 99% of dissolved solids, including lead, fluoride, and nitrates.
Yes, it’s a splurge—around $150 to $600 installed—but it’s the same tech used to make bottled water for your favorite influencer’s Instagram story. The trade-off: RO systems waste about three gallons of water for every one they filter. But modern units are getting smarter, some recycling that waste for your garden.
