Mineral Water In Your Home

Start drinking clean healthy water with the minerals you need like Calcium, Magnesium and Potassium. Keep your energy up with antioxidants and increased oxygen levels in your water. RO Alkaline water features higher pH than an ionizer can produce to balance your water. Choose the only alkaline filtration with 5 stages of mineralization. Start drinking healthy today!

5 Stages of mineralization combine with 5 stages of RO filtration to make the only 10-stage system offering the most complete water!

• Express Water’s 1st stage is a Sediment filter that targets dirt, dust, sand, and rust.
• The 2nd and 3rd stages are Granular Activated Carbon and Activated Carbon Block Filters which focus on pollutants like chlorine, volatile organic chemicals, and odor causing compounds.
• These early stages help extend the life of the 4th stage, the Reverse Osmosis Membrane. The membrane focuses on the most difficult impurities like lead, arsenic, chromium, fluoride, TDS, radium and others.
• The Alkaline Filter then adds 5 stages of mineralization, antioxidants, and oxygen to your water. One for each Active Mineral stage your water flows through. Our minerals are ionically activated so your water picks up more mineral content as it passes through five stages of mineral rocks. The same way the healthiest natural springs on Earth add minerals.
• The 10th stage is a Post Activated Carbon Filter which does a final pass on your water, right before it comes through the faucet, removing any possible taste or odor.

It’s the combination of these stages that has given countless customers water purer than bottled water straight from their faucet.
