www.waterfilters.net Aquaman tests the Katadyn Vario by drinking filtered water from a pond. The Katadyn Vario is capable of filtering out dangerous microorganisms like cryptosporidium, giardia, and coliform bacteria all while making the water taste great regardless of the source. If you are camping, hiking, backpacking, or otherwise in situations where you need to filter water of an unknown quality, you can trust the Vario. Built tough for expeditionary use, the Vario is heavy duty without being heavy. It's small, lightweight design is perfect for portability and it delivers on what it promises. The Vario uses a ceramic filter, combined with a pleated polyester and carbon cartridge to produce really good filtered water from really nasty, contaminated sources. With an aging infrastructure and boil water advisories increasing annually, every home should own a Vario for emergency situations. Like a fire extinguisher that you hope never gets used, the Vario offers the assurance of pure, safe drinking water should an emergency present itself.Aquaman is a Water Quality Association Certified Water Specialist.
