<p>There are a few questions regarding safety of water purification, one regarding expiration date, another regarding iodine, but I know that there are more than one types of water purficiation tablets.</p> <p>If I am using a water-pump filter. Is it necessary to combine this with a water purification tablet? Katadyn, a water filter company, suggests doing so.</p> <p>However, this makes me question the safety of putting such chemicals into my drinking water. In general, is it best to just avoid it? Or are there any water purification tablets that are proven safe?</p>
