Different Types of Water Purification Tablets

The leading chemical ingredients in these choices are iodine, chlorine and chlorine dioxide. These chemicals swiftly exterminate parasites, viruses and bacteria that are found in contaminated water. Iodine and chlorine are very good in eradicating the giardia lamblia–parasite that inhabits and breeds in the small intestine. However, they cannot remove the cryptosporidium–a parasite that produces gastrointestinal indications and is contaminated and passed in the feces–from the source of water. On the other hand, chlorine dioxide is very efficient against viruses, bacteria and cysts even cryptosporidium.


Potable Aqua Water Purification Tablets With PA Plus - Two 50...

If you are using iodine products for water purification , you have to be cautious of the water’s temperature that you want to purify. You need no less than 30 minutes of purification if the polluted water has a temperature of about 75 degrees Fahrenheit. However, you need no less than an hour of purification if the polluted water has a temperature of 40 degrees Fahrenheit. Understandably, cooler water needs to be purified longer than warmer water. Iodine tablet for potable drinking water can produce a different flavor in the tongue. So, if you are consuming this option, you can put iodine neutralizer products to counterbalance the iodine’s taste. Iodine products can only be used by people with a standard thyroid function for a short period of time, approximately six weeks at maximum. Remember not to use iodine products if you already have thyroid complications, iodine sensitivity or when you are expecting a baby.


The most extensively used chemical ingredient in purifying pill is chlorine. Chlorine products are the swiftest pills to make the water decontaminated. However, one downside in the usage of chlorine is that the water that is treated with it will become inevitably contaminated again in the course of an elongated storage. Chlorine products for potable drinking water can have a different taste and in order to eliminate the chlorine flavor, one has to permit the preserved drinking water to sit unprotected. This option permits the chlorine to evaporate without problems.

Chlorine Dioxide

On the other hand, the most efficient chemical ingredient in some of these options is chlorine dioxide because it exterminates an extensive collection of microorganisms. Chlorine dioxide products work via oxidation and infiltrate the microorganism’s cell walls and then respond with vigorous amino acids in the cell’s cytoplasm to destroy the microorganism. However, one disadvantage of the usage of chlorine dioxide is that it takes longer to purify the contaminated water than iodine or chlorine. Chlorine dioxide based tablet requires a 4-hour treatment period before it takes effect. Note that these offers that hold chlorine dioxide only create chlorine dioxide when they come into interaction with moisture or water. When these choices are wrapped in a strong package they can be stored for years and can immediately be used when needed.
