Nothing is more important to human existence than safe drinking water. Many remote places, where outdoor lovers venture, offer only lake or river water. Many parts of the world do not have safe water supplies. Visitors to these areas may not have the same immunity that residents have developed and may suffer tremendously without a way to purify their drinking water. Having the best water purification tablets is one way to be sure you can make potable drinking water virtually anywhere.
1. What Are Water Purification Tablets?
Water purification tablets are packaged products that enable people to purify specific quantities of water in a short amount of time. The best water purification tablets are packaged securely in single application doses to keep them dry until needed. They are easy to use by mixing with water and waiting the prescribed time before drinking: from 30 minutes to four hours depending on the product.
2. What Are the Types of Water Purification Tablets?
There are several different chemical formulations for purification tablets, including chlorine based, chlorine dioxide based, iodine crystals tablets and iodine tablets. Only the chlorine dioxide based tablets have the ability to handle cryptosporidium. The other types work well for other contaminants.
3. How Do These Tablets Work?
These tablets mix with water and make water safe from bacteria, viruses, protozoa and other organisms. Many work in 30 minutes. Those made with chloride dioxide will even take care of cryptosporidium, but it will take four hours before the water is safe from this organism. Tablets can be usedin conjunction with water filtering systems, many of which are also portable solutions. Some filters will screen out cryptosporidium cysts, complimenting the work of iodine or chorine based tablets.
4. Can You Keep Water Purification Tablets on Hand?
The best water purification tablets have long shelf lives; as much as five years for the packaged product. The user should follow package directions for how soon they should be used once they are opened and exposed to air. The tablets are easy to pack in tackle boxes, backpacks and suitcases. The package specifications will give guidelines for how long water can be stored. For some products, the shelf life of the purified water is as long as five years.
5.How Does Water Treated With Purification Tablets Taste?
The best purification tablets are designed to produce safe, drinkable water. With safety as the first consideration, taste is still an important factor. Humans need about a half gallon of water a day and even more in hot, dry conditions. Drinking the right amount of water is much easier if it tastes good.
The chlorine-based tablets generally get positive reviews on their good taste or the absence of foul tastes or odors. The iodine-based tablets need help to overcome taste, odor and some discoloration issues. Some products have two stages: one to purify the water and the second to take care of taste and odor.

Where to Buy
Most of the best water purification tablets are designed to be easily carried and ready for use when needed by a single person purifying water for himself or herself. Some are designed to treat more water at one time, either for immediate use by a small group or for storage to have an emergency supply ready. The price range per quart or liter of water ranges from just pennies to a price close to that of a soft drink.
All Are Reasonably Priced
Given the important function these tablets serve, the price should hardly ever be a consideration in making a purchase decision. The products cheaper by the quart are the ones that treat a larger volume of water at a time. The most expensive are the chlorine dioxide based products that can handle cryptosporidium as well as the entire range of bacteria, viruses and other organisms that the other types of tablets also take care of.
Filters Work, Too
There are a variety of water filtering products designed for the same kinds of situations where tablets would be used. A good filter can strain out cryptosporidium cysts from water. When this combination of treatments is used, the less expensive chlorine and iodine based purifying products should do the job.
