    What Our Customers Say

    I recently had a water softener installed in my home and I couldn't be more satisfied with the service I received. They were knowledgeable and professional, taking the time to clarify all my doubts and explain everything thoroughly. Plus, I absolutely love the system!

    Maribel A.

    They were very thorough and did a wonderful job installing my water purification and softening system, very professional and knowledgeable. Would definitely recommend these guys to anyone that is thinking about purchasing a softening system.

    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!!
