Is Iodine Effective?

I have always used the "Potable Aqua" pills to treat water in the wilderness. Now I hear that they won't kill one or two specific water-borne diseases. Is this true, and if so, what can I do to kill the extra germs?

Answer:

Yes, sir, iodine tablets have a very poor kill rate for cryptosporidium—microscopic bugs that are really hardy. You can use a relatively inexpensive water filter first—the kind that removes only the larger critters, such as crypto and giardia—then use the Potable Aqua to kill bacteria and viruses. Or you can switch to chlorine dioxide tabs (Potable Aqua makes these too), which will, unlike iodine, kill everything. But be aware: Chlorine dioxide takes up to four hours to kill crypto.  —Buck

    I found out the hard way that I had become very sensitive to Iodine products many moons ago, back in the 70′s. I found or it found me, the 1st Need Deluxe Water Purifier..Most of the Units sold in stores are “Filters” not “Purifiers” so you have to buy add on’s to get what 1st Need does automactically…I have never been sick and if desperate you can run your own urine through it.Though urine is sterile when voided it just contains too much diluted salts which will make your thirstier and sicker.
