Alkalizer RO System — 5-Stage Alkaline Reverse Osmosis (Made in USA)

Every Alkalizer RO is made in the USA — and ours are built right here in Mesa, Arizona. Usually available same day; custom builds can take 3–4 days.

Standard reverse osmosis strips everything out of your water — including the healthy minerals. The Alkalizer puts them back. Two stages of remineralization after the membrane bring your water to a pleasant pH of 7.5–9.5, with a proprietary mineral blend developed by water-treatment experts with over 75 years of combined experience.

Five stages of filtration

1. Pre sediment filter — traps sediment, rust, and dust
2. Pre carbon filter — removes chlorine and other chemicals
3. 50 GPD membrane — removes most chemicals, microorganisms, sediment, and salinity (standard or high-efficiency “Green” membrane available)
4. Calcite filter — water drips through after the membrane for maximum mineral adsorption
5. Alkalizer filter — the final stage before your faucet: activated carbon polish, KDF 55, calcite, and the mineral blend

Why this one

• Removes 90–99% of most contaminants — lead, arsenic, fluoride, chlorine, nitrates, and more (full rejection chart in the spec sheet)
• Optional “Green” membrane wastes only 1 gallon per gallon produced — a quarter of the waste of a standard RO
• Every unit is leak- and water-quality-tested before it leaves the factory
• Faucet styles and finishes available to match your kitchen (603 / 905 / 888 series)
• Five-year manufacturer warranty
