What Are the Risks?
Undertreated water is a wonderful home for microorganisms such as viruses (polio, hepatitis), bacteria (cholera, salmonella, streptococcus), and parasites (Giardia Lamblia, Cryptosporidium). Exposure to these organisms can cause serious illness, and in some cases may be fatal.
These risks are avoidable when using the proper method of filtration. If you or someone you know travels internationally they need to look into a biological filter. The easiest to use are the filtered water bottles.
Filtered water bottles are great because you don’t make a scene and offend someone because your refusing to drink their water. They allow you to safely drink the water that you wouldn’t under normal circumstances.
