We are talking about water purification tablets. These tablets are useful for killing pathogens in water, which becomes safe and healthy for drinking for humans. 

Water purification tablets are becoming a common source of water among international travelers and people staying in flood-affected areas. These tablets are portable and effective in deactivating bacteria, viruses, and other pollutants in the water.

What Do Water Purifiers Protect Against?

The risk against pure water is increasing drastically, in this case, water purifiers prove to be more useful. Usually, there are three major risks against water – sediments, biological organisms, and chemicals, or toxins. Here are some pollutants, which water purifiers provide protection –

  • Sediments – Sediments are common pollutants in water. It usually contains solid things such as dirt, sand, silt, plant, and some animal matter. This can be easily removed using a filter or a cloth filter such as cotton, wool, or a t-shirt. 
  • Algae – Due to increasing industrial waste and worsening of climate change has resulted in the formation of green, blue, or brown slime to grow in still water. Algae can be mitigated and removed by using chlorine-based products, boiling, UV light, distillation, and other solutions.
  • Bacteria – Bacteria appear in water from namely a few reasons such as fecal waste of humans and animals, like cholera, shigella, and others. One can easily kill it by using chlorine and iodine compounds, UV light, reverse osmosis, and more conventional methods.
  • Protozoa – Protozoa are advanced single-cell organisms reliant on organic matter. In North America, a common example of Giardia, cryptosporidium, and cyclospora has been observed majorly. The issue of Protozoa can be resolved using iodine.
  • Cysts – Cysts are a different type of water risk. These are present in inactive forms holding a resemblance to bacteria and protozoa. The inactivity of cysts come to halt once they enter our body. It can not be treated with iodine.
  • Viruses – Viruses are one of the major reasons causing Hepatitis A, SARS, polio, and other diseases. Viruses can be killed and handled by using iodine.
  • Chemical waste – The most common pollutants in rivers are chemical waste. Several factors are responsible for chemical waste such as pesticides, oil, industrial waste, and much more. Some particles can not be completely removed, however, you can use reverse osmosis, water purification tablets, flocculants, and more.

Features To Consider Before Buying Water Purification Tablets

Before settling for any water purification tablet, you must look beyond the price, brand, and online reviews. There are several factors like shelf life, access to clean, weight, and water systems you must consider before shopping for any product. Here, we have lined out some necessary features you can look for.

Process of Purifying

If you are a traveler and stay away from home, you will most likely face the situation of getting proper drinking water. In such cases, you can rely on water purification tablets. Most of the brands offer quick and easy methods to purify water. For instance, several tablets start working within 30 min and you can save your time and energy in purifying the water. Take a water purifier test and use the process at home to ensure that the process is suitable for you and your health.


Water purification tablets have close to no weight. However, the weight can be varied if you are storing these in large quantities. Most of the wanderers store these necessary items in advance, which might be useful but can affect the traveling weight of luggage and backpacks. Look out for different water purification tablets and how less it will impact the luggage’s weight while also managing to purify the water.

Taste and Smell of water

When it comes to drinking water, most of the people neglect the issue of taste and smile, rather cherish the privilege of drinking water. However, if you are planning to use the tablets for a long time, then you must consider how its taste and smell would impact you. To normalize the smell, you can use a neutralizer, but it would be suitable if you buy a tablet that offers proper taste and smell. Additionally, if the water purifying tablet you are willing to buy comes with a smell of chlorine, then you can remove it by letting the purified water sit uncovered, which will allow the chlorine to evaporate from the water.

What can the tablets fight against

This is the most important factor to consider before buying any water purification tablet. You must be aware of the bacteria viruses the tablet can fight against. Although, you must look for those tablets containing elements that are capable of combating bacteria viruses cysts, giardia lamblia, and cryptosporidium cysts. Most of these tablets consists of chlroine dioxide, iodine, and other elements with a shelf life of three to five years.

What Types of Water Purification Tablets and Drops Are There?

There are several types of products used for the purification of water. Most of them have a close resemblance to distillation and reverse osmosis. Here we have listed some of the most common types of water purification tablets and drops.

Solid Chemical Tablets

Solid chemical tablets are individually wrapped and closed tablets just like other medicines. These are usually coin-sized and easily portable. You can drop these in your water container to get purified water.

 Liquid Chemical Drops

The liquid chemical drops hold a similar idea as solid chemical tablets. These drops are individually stored in the liquid form and can be used using an eyedropper. Drop a few drops according to the requirement to purify the water.

UV Light

Many purification methods include UV light as portable water purifiers. This type is present in the form of a wand or pen, which can stick into the water. Or, it is usually built into a bottle wall or cap.


This process is quite different from other methods. It uses a kind of gel that circles contaminants, which cause them to merge, collect, and solidify into a bigger size. These chunks fall to the bottom that can be easily removed and filtered.

Why Do You Need Water Tablets?

With increasing issues of people drinking contaminated water, water purification tablets are becoming a prime source to purify water. Here are some reasons why you need water purification tablets.

  • Water purification tablets are responsible for cleaning harmful pathogens from water. As most of the tablets consist of iodine, chlorine dioxide, or chlorine, which is robust enough to kill disease-causing bacteria, viruses, and more. Apart from killing the viruses, water purification tablets also keep the water pure and bacteria-free for a longer tie. This process ensures that there will be no further growth or development of any harmful elements.
  • The best reason for buying water purification tablets is the mobility factor. These portable solutions are easy to carry and can be used while traveling. You will not need any additional baggage or previous set-up to get pure water. With these tablets, you can take water from a lake, pond, or any place and drink it after purifying.

  • Along with portable features, water purification tablets are favored due to its easy to use and hassle-free factors. There is no need to conduct any previous set-up or process to begin the purification process. Some traditional methods used to take time with their process like ultraviolet radiation, filtration, or boiling, which is not the case in water purification tablets.

How Do Water Purification Tablets Work?

The purification chemicals comprise iodine, chlorine, or compounds relevant to these elements. These elements are effective in purifying water without any hassle. However, it is usually said that mixed compounds are effective and preferred than pure elements. The mixed compounds are responsible for increasing shelf life for almost five years, easy to use, and reliable.

The process of killing pathogens begins with the usage of iodine, chlorine, or chlorine dioxide. These elements attack proteins, amino acids, and cellular structures to remove impurities. Their effect can be severe enough to disrupt a microorganism’s metabolic function. 

To discuss the elements present in the purification tablets, chlorine holds a significant position. This compound consists of chlorine dioxide, sodium dichloroisocyanurate, sodium chlorite, and sodium hypochlorite. These elements, specially sodium hypochlorite, are usually found in household bleach and commonly used in most water purification methods and tablets.

Will Iodine Work Instead Of Water Purification Tablets?

Iodine and silver holds numerous qualities to kill and remove impurities from the water. However, their purity and properties usually get hindered with peddling or some other biological reasons. This can impact their performance of purifying water.

Iodine is a good solution for treating water, but it can be problematic for people with thyroid problems or pregnant women. This compound is effective in eliminating bacteria, giardia, or viruses within 35 min, but will not stand a chance against cyst and cryptosporidium. 

Iodine usually comes in liquid or crystal form, whereas the market consists of iodine tablets too. But these can expire after opening in three months. Iodine can be sensitive to water temperature too. If you are planning to visit cold places, then you might find it difficult to purify the water in cold temperatures.

How Silver Appears In The Process of Water Purification

When it comes to using silver for water purification, it comes with some technicalities too. Silver consists of antimicrobial properties, which has created some impregnated silver filters too. However, this scenario comes to shamble due to the exploitation of silver and turning it into colloidal silver. The impure silver works technically but can be unhealthy to your cells. This is why experts prefer and advise on chlorine-type products.

Guidelines By World Health Organization For Emergency Treatment Of Drinking Water

From western countries to Asia, the transmission of waterborne diseases has increased drastically. The list of diseases is neverending, and their treatment seems to be improving in tiny steps. To prevent the development of diseases, the World Health Organization has worked rigorously and globally. WHO has produced and worked on a series of guidelines to enhance the emergency treatment of drinking water.

The response toward this global issue works upon the implementation of Water Cleaning Plans, which would manage risks from different carriers, catchment to consumer. The plan targets providing health-based and effective measures to ensure the safety of the public. WHO also focused on the development of guidance materials and providing direct support to various countries. With strengthened surveillance practices, the security of water purification system will be boosted to a new and safe level.

How Global Organization Come Up Together To Provide Pure Water Across Countries

The World Health Organization has been globally responding and testing household water treatment products. Two main practices have been observed mainly – WHO International Scheme to Evaluate Household Water Treatment Technologies and another project with UNICEF. The first practice focuses on protecting users from the pathogens in water and the second practice is working on sanitation and hygiene in medical facilities. Along with these organizations, several international government parties and communities are riogrously running campaigns to provide proper drinking and clean water facilities.
