Some time ago I corresponded with Doug regarding his use of Potable-Aqua Iodine tablets used to purify water in his mini-kit. These required a glass vial for safe storage.<br><br>I was just wondering if the Katadyn Micropur tablets might be a better option? They are much smaller and would consequently take up less space and they come in a plastic bottle so storage in small plastic vials (much more readily available) should not be a problem.<br><br>Just a thought/comment/query<br><br>John M

well here in europe (the netherlands to be axact ) ionide is not approved so the the only waterpurification tablets we can get here are cholerine tablets ( or drops ) like the Katadyn Micropur tablets, so we don't have packeging problems round here with corosife ionide tablets. Personally i perfer aquaclear tablets or puritabs in my PSK, since the come in foil packeting witch is easyer to pack, but they aren't aproved in the US...<br>

Actually Katadyn Micropur tablets are silver based.

They have some advantages like easier storage and a long shelf life. They do not change the taste of the water. You just have to deal with their disadvantages. They need a long contact time and you shouldn´t use aluminium bottles for storage. Because of the silver, it´s not recommended for use Micropur over a long period (for survival or camping this shouldn´t be something to worry about). I use Micropur tablets for their advantages.

ohw.. but ehh...are they as effective a chlorine and iodine ?<br><br>

Katadyn claims that they kill bacteria reliably. It takes more time though.
