The USO-3 Ozone Water Purifier purifies your tap water with safe, sterilizing ozone, right at home.

With a USO-3 you no longer need to have water delivered to your home; no lifting, no more wasted money and no valuable storage space filled with large bottles.  Tap water is exposed to ozone inside the unit, run through a special filter, and then sent to your faucet automatically.  A periodic filter change is the only maintenance the unit will need.

Ozone cleans water effortlessly and is great for municipal and treated deep well water.  It's not for use with untreated well water contaminated with iron bacteria, sulfur or iron.  With this system you can safely reduce:

  • Chlorine taste and odor
  • Trihalomethanes and chloroform
  • Heavy metals, lead, cadmium and mercury
  • Giardia cysts and cryptosporidium

It pays for itself

If you're using bottled water, the USO-3 can save you a lot of money and hassle over time.  The operating cost is just pennies every month and you use all the water that passes through - there isn't wasted water like with reverse osmosis.  A reverse osmosis system may only give you one gallon of pure water for every four gallons used - you don't have to worry about that with this ozone system.  

It's very easy to have clean water that meets and can exceed standards for bottled water and the US Clean Water Act.  You don'y need special tools and there's no complicated setup.  It's portable and free standing.  If you move, you can take it with you.
