  • “Huge mahalo to Dave for answering all of our questions and to bradda Pono for a smooth and quick installation. My wife and I love our X12. We fill our Yetis up in seconds. Used to take forever with the fridge. Huge peace of mind knowing we’re getting clean water, especially with the two keiki.”

    Kawika and Jordyn, Honolulu residents

  • "I love our water filter so much! We got the X16 and I could not be happier–just the peace of mind knowing what is and is NOT in my drinking water, tea, and the water I cook with. I don't even drink bottled water or restaurant water anymore. I only trust what comes out of my X16. Thank you!!!"

    Shayna, Kaimuki resident

  • "Filtered Hawai’i changed our entire outlook on the importance of how having an efficient reverse osmosis system can impact our entire lives! It started with the education we received from the web site and their representatives. After learning about the abundance of heavy metals that were found in our tap water system, it was a no brainer to have a system installed."

    Alex and Lila, Koa Ridge residents

  • "We can taste and feel the difference with our new system.. we now use it not only for drinking water but also for washing fruits and cooking. Now as we want to expand our family, this gives us even more peace of mind that having clean water for our health and generations to come will add years of great health to our lives!"

    Alex and Lila, Koa Ridge residents

  • "I have low water pressure at my house and [after installing the 3-stage whole house filter] can't tell the pressure loss. It’s not blazing out the tap but has good flow. Can taste the difference."
