What does reverse osmosis remove?

RO removes 90%+ of total dissolved solids (TDS), including lead, arsenic, fluoride, nitrates, pharmaceuticals, and microplastics. It produces water that's purer than most bottled water brands.

What's the difference between the three Thirst RO systems?

The Pure ($795) delivers standard 5-stage purification. The Restore ($895) adds alkaline remineralization to keep trace minerals and electrolytes. The Thrive ($995) provides enhanced alkaline filtration with balanced pH for the healthiest water. All include NSF certification and professional installation.

Do I need a water softener with RO?

While RO works without a softener, pairing them extends the life of your RO membrane significantly. Hard water can foul RO membranes faster. Our Softener + RO bundle saves you $450 and gives you complete water treatment.

“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 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.
