“When I called ONIT Water I was genuinely amazed at how helpful they were. Even though it became clear within minutes of the call that I was asking about a service they didn't even provide, Brad stayed on the phone with me for another 30 minutes just to help me find my own solution. He didn't try to sell me anything; he was just kind, transparent, and extremely helpful through and through. I don't think I've ever written a review for a company before, but they definitely earned my future business should I ever need their services. ONIT just REALLY want's everyone to have clean water, full stop.”

“Our home inspection company offered us a free water test and since we were new to the area we thought it would be a great idea just to see the results. Brock was our representative and he was awesome! He was very knowledgeable and personable! It was an exciting experience almost like a science experiment but it was also scary to hear that there are acceptable levels of toxic chemicals allowed to be in the water we use everyday! It was a no brainer for us to invest in the water filtration system and we love!!! It has saved us so much money and it has done wonders for our skin and hair! I would highly recommend you setting up an appointment to allow Brock to come perform a water test at your home! You would be surprised!”
