What customers say about our reverse osmosis

Just got an RO system installed by Shawn Parkes and I’m so happy I went with Clear Water for the install! He was extremely friendly, knowledgeable, and efficient. Would absolutely recommend Shawn and Clear Water to anybody in the San Tan Valley area looking for RO or other water solutions.

I cannot say enough good things about Clear Water Concepts/Absolute Osmosis! We live in North Tucson, where the water is extremely hard, so we shopped around and looked at several different companies before making our decision. Our sales representative, Moses, was excellent. He took the time to explain all of our options and discuss the different types of systems available on the market so that we could make a truly informed decision. At no time did we feel pressured to purchase anything, unlike some of the other companies we considered. The installation was exceptional as well. If you live in Tucson or surrounding area, ask for Mike as your installer! He has years of experience and took his time to make sure everything was done perfectly. I honestly don't think I've ever seen a plumber use a bubble level before—but Mike made sure every pipe was precisely level and professionally installed. He also carefully sealed any wall penetrations that were necessary and left the work area cleaner than it was when he arrived. After the installation, Mike took the time to thoroughly walk us through both our water softener and reverse osmosis systems to make sure we understood how everything worked. If you are looking for a stress-free experience purchasing and installing a water softener and/or reverse osmosis system, I highly recommend Clear Water Concepts/Absolute Osmosis. From the sales process to the installation, the entire experience was outstanding!

Jared was very conscientious and professional. He checked our reverse osmosis system and changed the filter. He advised us what to watch for and how to prolong the useful life of our system. Thank you Jared.

My reverse osmosis needed to be replaced. Clearwater had been changing the cartridges in the RO system, and when I called, they came out to inspect, and recommended a new unit based on the current condition of mine. I got a quote right away with discounts that they applied because I’ve been their customer in the past. The work then got scheduled. Mike showed up right on time and completed the installation in no time at all, very professional he was. Cleaned up after himself and put it in a position under the sink that made the area more usable. I was very happy and satisfied with the work that was done. And definitely recommend Clearwater.

Michael the tech was a little behind on arrival time but not his fault. Called to let me know that they had dispatched to a different address as i live in Rancho Sahuarita.When he arrived he explained the process of installing the equipment and got right to work. Michael did an excellent job explained how the Softener and the RO system worked . Thank you Michael and Clear Water Concepts for your excellent service and thank you Kyle for recommending this new system.

We had a RO system installed in our home in the Villages in Queen Creek, AZ by Clear Water Concepts. We were very happy with the quality of the unit, and with their employee Ari, who installed the system and described it’s use very clearly. He was on time and friendly, and he cleaned the space where he was working. I would definitely refer them to you. Having clean drinking water is so important. Ari tested our water from our refrigerator system and it was almost as high as our tap water!! Eek! Extra scary as we live near the golf course (pesticide..). 💯%

About Reverse Osmosis

Reverse Osmosis Drinking Water Systems in Phoenix & Tucson

Phoenix and Tucson tap water is safe to drink by EPA standards, but the dissolved-solids load — calcium, magnesium, sodium, chlorides, sulfates, occasional nitrates from agricultural runoff — gives our local water its distinctive mineral taste and leaves spots on glassware. A reverse osmosis system installed under your kitchen sink fixes both. RO membranes filter water at the molecular level, removing 95–99% of dissolved solids along with chlorine, fluoride, lead, arsenic, and the chloramines that typical pitcher filters can't touch. The result is bottled-water clarity and flavor at a fraction of the cost of buying jugs, plus an unlimited refill rate so you never run out.

Clear Water Concepts has designed reverse osmosis systems for Arizona homes since 1998. We size the membrane to your household demand and the storage tank to your peak draw — important in the desert Southwest where high TDS levels stretch RO membrane lifespans if undersized. Our systems include high-quality pre-filtration to protect the membrane from sediment and chlorine, post-carbon polishing for taste, and a leak-detection auto-shutoff so a slow drip doesn't become a kitchen-floor flood. Connect to your refrigerator's ice and water dispenser, your kitchen faucet, or a dedicated drinking-water tap — most of our customers do all three.
