Criteria Used for Evaluation


When it comes to the water we drink, we want it to be the purest possible. For this reason, when using water purification tablets we need them to be effective. One tablet is usually able to purify a maximum capacity of 2 liters of water. The effectiveness of a water purification tablet means the difference between drinking something pure or putting pathogens and other bacteria into our body which can harm us.


The potency of water purification tablets is much the same as the effectiveness. When we are out camping and get thirsty, we need something to quickly and efficiently purify the water we intend to drink.

Some outdoor enthusiasts bring their own purifying filters with them when venturing out into the wilderness to have clean water. However, these filters are only able to capture and eliminate debris, parasites, and certain bacteria. Some of the bacteria and viruses living in the water are too big for the filter to remove. This is when the potency of a water purification tablet is important. Which brings us to the next important criteria– product purity.

Product Purity

The purity of the water we drink is probably more important than the food we eat. It is a known fact that the human body can do without food for up to 21 days and survive. However, we cannot live without water for more than 100 hours. It is not only necessary to have water for hydration purposes, but it must also be free from toxins, bacteria, and pathogens.


The water purification tablets we use for purifying our water must be able to react quickly. When out in the wild, or during a state of emergency, when we are thirsty we need pure water right away. We should be able to simply drop a tablet in some water and have it ready to drink instantly.


This feature is important because of how and when we need to use water purification tablets is essential. The most common use is when out camping or hiking. We normally bring water in our canteen to drink, however, this can run out or even become contaminated due to exposure to the sun and other elements. For this reason, having water purification tablets at our use is very essential when trying to survive off the grid. We can gather some recently fallen rainwater, or the water in a creek or stream, place it in our canteen and drop a water purification tablet inside. Instantly, we have a potable drinking source! It is that simple and easy to do!

Expert Tips/Advice

There are two primary basic needs we need for survival, and that is oxygen and water. Since there appears to be plenty of fresh oxygen worldwide, you just need to ensure to find adequate water for hydration.

What to Consider When Buying Water Purification Tablets

The first question you may have when looking for a brand of tablet to purify your water, is are they all created equally? The main elements that makeup purification tablets are chlorine, chlorine dioxide, and iodine tablets. If you are trying to rid such parasites at the Giardia Lamblia, then chlorine and iodine will do just fine. However, it may not be enough to rid tougher viruses such as the Cryptosporidium. This is when you require the power of chlorine dioxide. Water purification tablets that contain chlorine dioxide work best to eliminate the toughest bacteria, viruses, cysts, and even cryptosporidium

Another positive attribute in regards to chlorine dioxide is that unlike chlorine and iodine it does not have any unpleasant odors. The reason for the lack of smell is probably due to the time it takes to purify the water. When you use chlorine dioxide it takes about four hours to treat water, this time for treating the water permits the odors to evaporate.

Why you should bring Purification Tablets along on Trips

The levels of contamination can vary depending on where you may travel. If you have purification tablets in your possession, you can kill any bacteria that may be in the water.

You will soon discover that water purification tablets are good for so much more than emergency situations. Water purification tablets will work great when you go camping, hiking, or any place that might take you off the grid. Water purification tablets are recommended for when the water is muddy and contaminated and particularly during an emergency situation.

Other Factors to Consider


This factor is very important when considering water purification tablets. The tablets you buy should be packaged in a manner that makes them easy to be transported. Some tablets are packaged individually, this allows you to store the tablets in a purse, backpack, or carry on luggage. Having easy access to the purifying tablets ensures you will always have a way to purify the water you are about to drink.

Devices used for treating and purifying water need to be as portable as possible. This ensures the easy transport of chemicals to the areas of contamination. It is imperative that water treatment units be portable in order to get to the areas where hikers, backpackers, military personnel or others in danger of ingesting contaminated water may be.

These are all the factors you should consider when looking to by the best water purification tablets for your trip or survival bag.
