What Are Water Purification Tablets?
Backpackers, outdoor enthusiasts, international travelers, and people in natural disasters often use water purification tablets. They are small tablets you put into the water that help kill any pathogens. As a result, you’re guaranteed to have safe drinking water available.
How Do Water Purification Tablets Work?
Purification tablets usually contain chlorine, chlorine dioxide, or iodine. These chemicals can break down and disarm harmful bacteria, viruses, and parasitic protozoans common in contaminated water sources.
The chemicals work by breaking down the cell membrane of harmful microorganisms, which allows the chemicals to enter and deactivate the cells. After the tablets have done their work in the water, you can safely drink without worry.
How Long Do the Tablets Take to Work?
How to use water purification tablets can differ between products. Always look at the instructions carefully before using water purification tablets. The time to fully purify the water sample can be from 30 minutes to 4 hours.
In general, you check the mixture ratio for your product. Place the correct amount of tablets into your water. Wait for 30 minutes or so, and you’ll have potable water.
Some people say the tablets make the water taste bad because of the iodine or chlorine. There are iodine neutralizer tablets to help with the iodine flavor. If you want to remove a chlorine flavor, just let your water breathe. The chlorine will evaporate from the water, and you’ll have a clean, flavorless product left behind.
What Are the Pros And Cons of These Tablets?
Pros: There are many pros and cons of water purification tablets. Some pros include convenience, portability, and a long hold time. Many purification tablets stay good for many months, making them essential in emergency and survival kits.
Also, you don’t need to be able to build a fire to achieve potable water when you have water purification tablets. In a survival situation where you are at serious risk of dehydration, easy access to safe, drinkable water will help greatly. A person can only go up to 3 days without water, so it is essential to have multiple ways to get this vital resource.
Cons: There are some health concerns regarding the long-term use of water purification tablets. They’re sufficient for a quick lifesaver in a pinch, but you don’t want to use water purification tablets in large doses for extended periods.
The chemicals and byproducts of the breakdown remain in the water, and you could face trouble over time. Also, the tablets usually leave a residual taste in the water.
Pro Tip: Water purification tablets aren’t the only way to purify water. Check out these 5 Ways to Purify Water for Survival in the Wilderness.

What Is the Most Effective Way to Purify Water?
Boiling water is a standard and effective way to purify water. Consistent high temperatures make unpleasant things in the water die and break down. Ensure you bring the water to a rolling boil, then boil it for at least 20 minutes before cooling and drinking.
However, unless you bring fire starters with you or you are skilled with a ferro rod, sometimes boiling water isn’t the easiest task to accomplish. Purification tablets are a great failsafe backup if a fire is out of the question.
