Below I’ve discussed this question – Are water purification tablets safe? Water purification options come in water purification tablets, powder, or liquid form.
They contain iodine and chlorine as disinfectants. You can add these tablets to untreated water to fight harmful microbes.
Therefore, make the water safe for human consumption. Also, check this guide that examines if water purification tablets expire.
So, Are Water Purification Tablets Safe?
Yes, water purification tablets are safe. They’re a great choice if you suspect your water has been contaminated. Water purification tablets are among the best and effective methods for purifying water.
These tablets come in handy while camping or hiking in the wilderness where access to safe water is a challenge.
For starters, your bottled water can run out while going hiking or camping in the wilderness. Your best or only option to quench your thirst can be a stream, lake, or waterfall.
Nevertheless, most backcountry hikers and those that love remote camping trips depend on such water bodies to replenish their water source.
But, such waters contain plenty of microbes that can cause serious health issues to humans.
Therefore, drinking such untreated waters can cause mild diseases. These diseases include:
- Or even more severe diseases such as meningitis and hepatitis.
According to McClung et al. (2017), in 2013–2014 the United States reported 15 waterborne disease outbreaks. These outbreaks resulted in 289 cases of illness, one hundred and eight hospitalizations, and seventeen deaths.
Legionella (a type of bacterium found naturally in freshwater environments, like lakes and streams) was responsible for 94% of hospitalizations, 63% of the outbreaks, and all deaths.
McClung et al. also reported another outbreak of giardiasis. This outbreak was caused by drinking untreated water from a spring, river, and stream.
Application of Water Purification Tablets
Therefore, it is crucial to disinfect all water prior to consuming it. You can add water purification tablets to unsafe or untreated water.
This way you fight disease-causing microbes like viruses, bacteria, & protozoa. Thus, make water safe for consumption.
Most people prefer these tablets because of their simplicity and portability. Using these tablets is quite simple;
- Filter the untreated/dirty water through a cloth or filter
- Drop one tablet in two liters of water
- Wait thirty minutes
- Drink your water without fear.
These tablets work by releasing essential chemicals into the water which kill harmful microorganisms.
They are used when a natural disaster occurs and interrupts the distribution of safe water. They are also used during hiking and camping in far-off places where access to clean water is limited.
Hence, adding these tablets directly to untreated water destroys microorganisms.
Water purifying chemicals have different action mechanisms. Each of the said actions has a specific period needed for it to dissolve properly and show desired results.
Different factors determine how well a purifying chemical can act and kill harmful microbes. Thus make untreated water safe for consumption.
Such factors include;
- The time is given for the tablet to dissolve
- The level of dirt in the water.
However, not all microbes or pathogens get completely removed by the Water purifying chemicals.
Backer, (2019) insists that boiling untreated water is the only recognized and recommended way of treating water.
However, boiling water is not always practical or possible especially after a disaster or while traveling in remote locations.
Therefore, ensure you use water purifying tablets each time you suspect the water is unsafe.

How Do Water Purification Tablets Work?
These purification tablets are generally iodine and chlorine. These two are very effective and are a great choice for the water purification process.
The active ingredients in these tablets work by deactivating micro-organisms like bacteria, viruses, and protozoa found in rivers, streams, or springs to make the water safe for drinking.
Such micro-organisms facilitate the entry of diseases into the body to cause mild to severe illnesses or even death.
Water Purification Tablets Side Effects
Some Water Purification Tablets have negative health outcomes for some people.
For example, iodine water purification tablets can cause health risks to pregnant women, individuals with thyroid conditions, or those with iodine allergies.
Water purifying chemicals will not completely eliminate all microorganisms. Over time, some of these chemicals can lose their effectiveness, especially if kept improperly.

Iodine water purification tablets can also affect the overall health of a user, especially when used for longer periods.
Known side effects of prolonged iodine intake include stomach pain, headache, nausea, diarrhea, and metallic taste.
Individuals with autoimmune thyroid disease are particularly sensitive to iodine and its harmful side effects.
The threat of poisoning by water purifying tablets is dependent on various factors like type and amount of product consumed, the user’s age, and their overall health.
Water purifying tablets have become a quick choice for many. They have proved useful in eliminating water-borne diseases. However, a person especially children can mistakenly consume them because of their edible nature.
