Water Purification Crystals

USP Iodine in 1 Ounce bottle

Each amber bottle contains 8 grams of USP Resublimated Iodine Crystals.  It may be reused to treat up to 5000 quarts. Once the crystals are dissolved, the bottle is finished. This may take years!

Each fill of the bottle will give you a saturated solution of 8 ppm (parts per million). This solution strength will disinfect water according to the following table:

Iodine is light sensitive and must always be stored in a dark bottle. It works best if the water is over 68° F (21° C). Iodine has been shown to be more effective than chlorine-based treatments in inactivating Giardia cysts. It is important to note that you are using the iodine solution to treat the water, not the iodine crystals. The concentration of iodine in a crystal is poisonous and can burn tissue or eyes.  Fill the bottle with some of the water to be treated, cap it, shake, and let it sit for a few minutes.  Decant the solution ( not the crystals) into a one quart ( 1 litre) container holding water to be treated. Let the treated water stand for 30 minutes before drinking. In order to destroy Giardia cysts, the drinking water must be at least 68° F (20° C). Be aware that some people are allergic to iodine and cannot use it as a form of water purification. Persons with thyroid problems or on lithum, women over fifty, and pregnant women should consult their physician prior to using iodine for purification. Also, some people who are allergic to shellfish are also allergic to iodine. If someone cannot use iodine, use either a chlorine-based product or a non-iodine-based filter, such as the PUR Hiker Microfilter, MSR WaterWorks, or the Katadyn Water Filter.

Always ensure the bottle is tightly capped, as iodine crystals sublime into the air quite quickly, and may stain surrounding items. They will also cause corroding of most metals. Leaving water in the bottle is okay, and will not create a superstrong solution. Any residual iodine aroma in the treated water may be neutralized by adding drink crystals containing vitamin C.

These items are for water purification use only, and are being offered for such purpose solely.
