What customers say about our reverse osmosis

Mike came to my home today to inspect and perform maintenance on my water softener and RO system. He was punctual, friendly, and efficient. I highly recommend calling Clear Water Solutions/Absolute Osmosis if you’re serious about having fresh, clean water without all the buildup from the hard water here in Red Rock Village. Two thumbs up! Great job Mike!

We live in Sun Lakes AZ, and after extensive research we decided to go with Clear Water Concepts, there upfront pricing on there website and a very thorough explanation of the system was exactly what we were in need of. On installation day our technician Ted was on time and very informative regarding the installation process. Ted installed a water softener and RO system in our home, the work performed was very impressive and detailed oriented. We are very pleased and would highly recommend them.

Clear Water Concepts installed both a water softener and an RO system for us and we couldn't be more pleased. Both Moses and Mike were fantastic to work with - friendly, efficient and knowledgeable. The communication from the time of quote through install was great. Our RO water tastes delicious and the soft water makes a noticeable difference in our hard water in Vail, AZ. Highly recommend this company & their products!

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 1985. 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.
