Let the World Be Your Water Bottle™

Whether your adventures bring you to a quaint sidewalk restaurant in a foreign land, or you just want to quench your thirst from a cold mountain stream, or you are not sure of your water source in a remote location, you can rely on the Roving Blue O-Pen™ to ensure that the water is safe to drink.

The O-Pen™ is the latest advancement in pocket water purifiers. It makes water safe by infusing it with tiny bubbles of ozone gas.  When its job is done, ozone reverts to oxygen in minutes, leaving no chemical residue, odors or tastes.

Approved by the FDA and the USDA for use in drinking water, ozone is more powerful than chlorine and is highly effective against bacteria, viruses, giardia, cryptosporidium, typhoid fever, coliform, dysentery, cholera, infectious jaundice, hepatitis, influenza virus, e-coli, enteric and many other dangerous microorganisms.

TSA approved to bring on board, you can be sure that the tap water in your hotel room, FOB or nearby stream, is safe to drink, because with the O-Pen™, you CAN drink the water!
