“⭐⭐⭐⭐⭐ We had an excellent experience with Clear Water Concepts from start to finish. Zack and Shaun came out to install our new water softener and reverse osmosis system, and they did an outstanding job. They were professional, knowledgeable, respectful of our home, and took the time to make sure everything was installed correctly and neatly. They also explained how the entire system works and made sure we understood everything before they left. What really stood out was the quality of their work and attention to detail. You can tell Zack and Shaun take pride in what they do instead of simply rushing through an installation. The difference in our water was noticeable right away. We are extremely happy with both the water softener and RO system and feel confident that we made the right decision going with Clear Water Concepts. Thank you to Zack, Shaun, and the Clear Water Concepts team for making the whole process easy and stress-free. I would absolutely recommend them to anyone in Arizona looking for a quality water treatment system and a company that actually stands behind its work. Five stars all the way!”

“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!”

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.
