First off i want to thank all the members that helped me on my camp stove question. I was wondering what people are using for water purification in the back country. One of my cousins has the stery pen he said i could use but should i get a pump filter as well. Are the tablets worth bringing. I supose to be safe just bring all four but who has room for that lol. again just looking for some guidence dont want to be buying junk or unnessesary things. Thank you
