The
O-PenŽ is a pen-sized water purification device that you can take anywhere. It can purify
16 ounces of water in under a minute using the power of ozone.
Ozone gas is approved by the USDA and the FDA for drinking water. It's more effective and powerful than chlorine without some of the health concerns of chlorine gas. Ozone is simply O3, three oxygen atoms that provide a punch against microbes and other contaminates. Since oxygen atoms group in pairs, the third atom breaks off and attaches itself to viruses, bacteria, and microorganisms that cause giardia, coliform, typhoid fever, cryptosporidium, cholera, dysentery, hepatitis, infectious jaundice, e-coli, influenza, enteric fever, and many more, inactivating them and removing the threat. Ozone also removes odors and bad tastes.
Because it's so small, the
O-PenŽ is easy to take anywhere. It only weighs 1.2 ounces. It comes with a USB cable and rechargeable battery. You can clean about 25 liters per charge, and the stainless steel cartridge makes it durable enough to pack and carry.
