What customers say about our reverse osmosis

We recently had the RO system in our Casa Grande home serviced by Clear Water Concepts. Clear Water installed the RO and softener system in 2023, and it has worked like a charm since installation. The technician (Jace) who did the RO service was excellent. He arrived early, answered all questions and promptly completed the servicing. If you need a great soft water system and a company that provides great service and reasonably pricing, don’t hesitate to call Clear Water Concepts.

Reliable and knowledgeable company. Our home is in Oro Valley. Mike did a fantastic job, arriving on time and explaining how the RO system worked. He examined my soft water system as well. He said an 18 month filter replacement was all that is needed, based on our water usage and filter particle accumulation. I will keep using them.

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.
