How Cloud RO Works

A lot of science 🧑🏽‍🔬 and a little magic. 🪄 Let’s take a look under the hood.

  • 99%Toxin
    (Kicks hundreds of toxins to the curb)
  • 1:1Low

    (80% better than traditional ROs)
  • 2xFaster

  • 8pHAlkaline
    All The Time
    (Added minerals provide an optimal 7-10 pH range)
  • Better Filtration

    ⛑️ Powered by reverse osmosis, our multi-stage filtration process kicks toxins to the curb. Cloud uses internal sensors to control the flow of water in the system to maximize filtration effectiveness, providing best in class contaminant removal. Cloud removes 99% of toxins in your tap.

  • Faster Flow

    ⏱️ The worst part about traditional RO systems is the trickle at the faucet. No more waiting around for your glass to fill, Cloud maximizes tank pressure and fills a typical 10oz glass in six seconds.

  • Less Waste

    ✌️ Cloud RO wastes 80% less water than a traditional reverse osmosis system. A permeate pump sends those toxins to your drain and fills a 2.8-gallon holding tank with pure water. Competitors waste up to 10 gallons of water for every gallon filtered, Cloud delivers an industry leading 1:1 waste ratio.

  • More Alkaline

    🔮 After your water has been purified it passes through one final ‘remineralization’ stage. Healthy minerals like calcium, magnesium and potassium are added back into your water. These minerals naturally raise the pH to an ideal 7.5-9.5 range, leaving your water perfectly alkaline.

Pure, healthy water, every single time.

Now that’s smart.

Smart sensors send water quality and filter performance right to your phone. Your water, at your fingertips. 🤌

  • Monitor Quality & Performance

    Filter replacements are recommended based on your household usage, not some arbitrary timeline.

  • Track Gallons Consumed

    Track how much your family is drinking and how many plastic bottles you have saved in the process.

  • Keep It Alkaline

    Keep tabs on your pH to ensure the water you are drinking is both pure and perfectly alkaline.

  • Toxins Out, Nutrients In
