I wouldn't think that it would be much different in taste than water treated using iodine crystals........or most types of water purification tabs. <br><br>I have and use both. In my mini tin kit, I use tabs in the small glass vials with teflon lined caps as suggested by Doug.....and have for a couple of years. I just have a very small, flat Omniseal waterproof wallet that contains some items, and I had thought about using the pad for its possible dual roles, since it is nearly impossible to pack tablets in any manner that would be flat (for a wallet or otherwise) that wouldn't result in their crumbling or going bad.<br><br>
