Coffee Filters Clean Waters A person can buy Water Purifying Systems, they have filters and you pump the water through the filter. I have never seen anybody on planet earth carry one for longer than three months before they stopped using them.
Buying water is easier than using these systems, however, expensive, about 3 US Dollars per day to drink three liters, I have trouble believing countries can be so cruel as to not provide free waters to their people.
I do not buy water often, I would just as soon die early, however I have started to boil water, I am slowing perfecting a system to boil water, and I also boil the purified water, because I do not trust companies that bottle water. I will soon make another video explaing a simple system to boil water for drinking, however today I was excited.
Coffee Filters, I can replace the sock system.
Buying them stupid filters for all the silly water purification systems above is close to impossible, I do not return home, they do not see them anywhere on the planet.
However, coffee filters, they do sell them anywhere on the planet for the most part, sometimes difficult, and maybe cheesecloth, whatever that is?
I can stop with the sock idea and move up to the coffee filter, there is no such thing as perfectly safe water, there is water that optimized for safety. I truly trust boiling water more than I trust a bottle of purified water. Getting the water to cool is the biggest problem with boiling.
Note, I would still just continue to drink the water, it has not killed me in 10 years of travel, and I have drunk the water in every country. However, I am starting to think that drinking the water causes my immune system to work overtime, I think maybe it will work less if I boil the water.
I need a water testing laboratory to send samples, if you know of a water testing laboratory in the USA that can do this job, please click on contact an write Andy of HoboTraveler.com. I am wanting to test the water around the world.
