We absolutely loved the process of getting a whole house water filter system. From the first text, Mason, the salesman was great, informative and super helpful. Also seems like a great guy.

Installation day was quick and smooth - only took a couple of hours and Thomas the plumber explained everything in detail.

Great initial water evaluation, installation and soon to be follow up.
We recently had a whole home system installed and LOVE it- just wish we did it sooner! From start to finish, the process was seamless. Our plumber Joe explained everything and was very knowledgeable about the product! We were amazed at how much sediment was in our copper pipelines-gross!! It’s a great feeling knowing we can drink water from the tap- no more plastic bottles! You can 100% taste the difference when drinking and our skin feels better after a shower. Highly recommend, you won’t regret the investment.

I had a great experience with pHountain Water Filtration. From the initial consultation to installation, everything was professional, efficient, and transparent. The team took the time to explain the system, answered all my questions, and made sure everything was set up perfectly.

The difference in water quality was noticeable immediately—cleaner taste, better clarity, and peace of mind knowing my family is using high-quality filtered water. Customer service was excellent, pricing was fair, and the whole process was seamless.

Highly recommend pHountain Water Filtration to anyone looking to improve their home or business water quality.
