San Antonio Water Filtration Solutions
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

Joseph E.
We recently purchased a new home and we knew that we were going to want and need a water softener, so we contacted Dupure and could not be happier with the response we have had. I couldn't or wouldn't recommend another company to combat San Antonio's hard water issues.
Irma H.
We have had a Dupure Reverse Osmosis system for 10 years and I don't think I'll ever go without one again. It's been amazing to see what food tastes like now using pure water to make it, and their customer service has been great over the years.
Gabriel V.
We’ve had our system for around 6 months now and we couldn’t be happier! My daughter has had terrible eczema her whole life and within a month of installing the softener/carbon filter it was completely cleared!!
