I've developed a habit of carrying a few water purifying tablets in my possibles pouch plus two or three in my wallet for those occasions when boiling is not convenient. I carry a millbank bag and a pump purifier in my pack on long trips and overnighters, but when out for a stroll I like have a few tablets in my pocket to add to my water bottle when I refill it from a mountain stream. I find that I often need to drink more than the one litre I'm prepared to carry so I need some purification system for refills.
When checking over my kit the other day I found the tablets I carry are well past their sell by date. On going to buy a new supply at a well-known high street camping shop, I found that they only offered one brand at a very high price and began to think about alternatives. My wife has an iodine intolerance and I don't like the taste much anyway so I have always used chlorine based tablets. I recall that when we used to live in the tropics, we used to purify our drinking water by adding a drop or two of ordinary household bleach to a litre of suspect water. I'm thinking about carring a small dropper bottle of chlorine in the pouch, although I worry about leakage, but can't think of a substitute for tablets in the wallet.
Does anyone know of cheap source of tablets? What system of water purification do you use for short trips?
