Since I have joined this forum I have heard a lot of bashing on filters (easy to cross contaminate, heavy, hassle to use, etc.) and I have heard a lot about not filtering or purifying at all. I have used a filter every time I go backpacking and have never been sick. Personally, I like filtering my water and don't understand all the bashing of filters. I don't see anyone sticking up for filters and everyone leaning towards purification or nothing at all (typically from ultralight backpackers).....Is there anyone on this forum who still uses filters?.....Is there anyone on this forum that isn't an ultralight backpacker?
