Clean, soft, and safe water for every home in San Antonio—with Dupure’s expert water softeners, reverse osmosis systems, and drinking water filtration.
Cleaner, Softer Water Where It Matters Most
San Antonio has a lot going for it—rich history, amazing food, and a culture all its own. Unfortunately, the tap water doesn’t live up to the rest of the city. With some of the hardest water in the country, San Antonio homeowners deal with everything from dry skin to cloudy glasses.
At Dupure, we provide under-the-sink water filtration, reverse osmosis, and water softener systems designed specifically for San Antonio’s tough water. If you're sick of dealing with bad-tasting water or crusty faucets, you're in the right place.

Why Is San Antonio Water So Hard?
Most of the city’s water comes from the Edwards Aquifer, which is full of naturally occurring limestone. That means the water is packed with minerals like calcium and magnesium—a recipe for hard water.
How hard water hits your home:
-Mineral buildup on faucets and dishes
-Skin and hair that never feel clean
-Dry laundry and worn-out appliances
-Off-tasting water straight from the tap
