This is a follow up to my earlier posting about various water purification methods in the field. Please note that everyone has their own particular field water purification needs and one-size does not fit all.
In my case, I occasionally travel through urban and semi-rural areas in East and Southeast Asia, and not always the most developed areas. I stay at hotels and hostels and there is usually running water although it may be suspect. I eat at street-side restaurants that may not be that hygienic. The food is usually ok because it's been cooked but the water/lukewarm tea that gets served is suspect.
So my water needs are to to easily purify tap and street bought water (clean but maybe virus or parasite laden). As noted in my previous post, the obvious and best solution for this is UV-C water purification. Iodine / chlorinated tablets leave a bad taste and take too long and water filters are a pain to use.
