One small 2" bottle contains 50 water purification germicidal tablets of 20mg tetraglycine hydroperiodide. Provides safe drinking water when used with proper filtration. Shelf life of unopened bottle is 5 years; but only 6 months after bottle is opened. Note: Iodine does not definitely kill cryptosporidium unless you combine treatment with proper filtration. Not Recommended for people with sensitivity or allergy to iodine.

What is Potable Aqua?
Potable Aqua® Drinking Water Germicidal Tablets make water bacteriologically suitable for drinking. They contain iodine in a proprietary compound called TGHP. Each tablet contains 20 milligrams of TGHP, which liberates 8 milligrams (ppm) of titratable iodine. As indicated by label directions, the recommended dosage of Potable Aqua is two tablets in one liter or quart of water. When the tablet dissolves in water, it releases both free iodine and hypoiodous acid. Both are effective germicidal compounds. Potable Aqua tablets also contain a buffering agent that brings the pH of the water to a slightly acidic level to optimize the disinfecting properties of the iodine.
How Does Potable Aqua Work?
Each Potable Aqua tablet contains 20 milligrams of TGHP, which liberates 8 milligrams (ppm) of titratable iodine. Dissolving Potable Aqua tablets in water releases the iodine bound in the TGHP molecule. When dissolved, both diatomic iodine (I2) and HIO are released. Because the tablets contain a buffer, the treated water is maintained at acidic conditions with an approximate pH level of 5.5. Diatomic iodine is more abundant than hypoiodous acid.
This mixture provides adequate disinfection of most waters. Chemical reaction rates, and consequently germicidal effects, are subject to variables such as water temperature and level of contamination in the water. For this reason, two tablets of Potable Aqua and a 30-minute waiting period are required before drinking the water. The iodine works by penetrating the cell wall of the microorganism, therefore rendering it inactive.
How Long Can I Use Potable Aqua?
Potable Aqua tablets are to be used as a short-term, emergency treatment for disinfecting drinking water. Potable Aqua should not be used on a long-term, continuous basis. According to label directions, the recommended dosage of Potable Aqua is two tablets in one liter or quart of water. This dosage is equivalent to 16 ppm of elemental iodine in the water. Since this product is intended for use in emergency situations, extended daily use should be kept to a limited basis and not exceed six weeks.
