Buying Guide for Water Purification Tablets and Drops

How to Choose the Right Purification Tablets for Me

The biggest thing to consider when deciding which purification tablet is the right choice for you is the main chemical that is being used for the purification process with the three of the most common chemicals being Chlorine, Iodine and Chlorine Dioxide.

Every single one of these chemicals has its own drawbacks and advantages which we discuss in a separate section further down in this article.

For What Type of Occasions Should I Bring Water Purification Tablets?

It is recommended to bring water purification tablets with you if you and your potential companions are planning to go out in the wild somewhere expansive where it is really hot and there is also not a large concentration of humans.

This is because such an environment poses a big risk if you get lost or injured in a way that stops you from being to leave the location that you are visiting, in such cases water purification tablets can save your life.

Of course, these kinds of extreme cases are thankfully very rare but it is still recommended to take water purification tablets with you when go out into the wilderness as it is much easier to carry a pack of tablets than liters of water.

It is also important to note that there are also special kinds of water purification tablets for emergencies such as natural disasters, these products are more expensive but are able to clean the water much faster.

Storing Water Purification Products

Even though the majority of the best water purification tablets out there come with many years’ worth of shelf life, it is still important to store the purification products properly as the shelf life is only reliable as long as the storing instructions are followed correctly. Every product is different so it is recommended to read the label in order to get an accurate idea of all the steps that you need to take in order to maximize the life of your product.

But to give you a few pointers, it is best if you store your water purification pills in a dark, cool location such as a cupboard where there is also very low humidity in order to prevent the products from breaking down over time.

How Are Water Purification Tablets Supposed to Be Used?

Water purification tablets have been designed to be fairly straightforward to use, all you really have to do is to drop the purification tablets in the water that you are trying to sanitize and then make sure to wait the recommended amount of time that it says on the label which is very important.

You need to know the exact amount of time that it takes as for example certain organisms in the water may take 30 mins to eradicate while others may take 4 hours.

Things to Keep in Mind When Choosing Water Purification Tablets and Drops

Quantity vs Quality

Sometimes you will find yourself in a situation where you can get a good deal by make sure that you do not compromise on quality. It may be tempting to pick the offer that seems the best value for money where usually you have one hundred or more water purification products being offered for a low amount of money.

There is nothing wrong with that as long as they do the job and are high quality, as you may find yourself with a lot of tablets that are weak so you will need to for example insert 2 tablets to clean 1 liter of water while a more expensive but higher quality product can clean 1 liter of water using just 1 tablet.


As stated further above, it is important to know about the ingredients that are used in your water purification tablets as at the end of the day you are going to be consuming the water after it has been treated therefore you need to be aware of the potential health risks or consequences if they happen to exist in the first place.

What Are They Created For?

If you are just an average lover of the outdoors, the standard water purification tablets will work for you. However, if you are for example in the military or in the natural disaster emergency service then will be a good idea to take a look at more specialized options that are able to clean water from dangerous parasites, bacteria and viruses very quickly which is essential as in such serious situations you cannot afford to wait potentially hours for your water to be sanitized.

Ease of Transport (Weight)

Another point that you need to consider is how easy is it to carry around the water purification tablets with you, this type of product is one that should not take up a lot of space or effort to take around with you.

Ideally, the best type of product in the ‘ease of transport’ category is one that you can carry in high quantities without any drawbacks such as being exhausted by the extra weight in your bag or not having free hands to use in order to better traverse your environment.

Recommended Dosage

Related to the ‘Quantity vs Quality’ section above, it is important to take note before you buy a product of what quantity of tablets you need in order to treat say 1 liter of water as this will give you a better idea of how to calculate the cost per tablet and the total value for money without being influenced by cunning marketing tricks.

Ease of Use

Another key feature that you should consider is how easy it is to properly use this product because the more complicated a process it is the higher the chance of you making a mistake and potentially falling ill if the water has not been properly purified from dangerous organisms.

A large part of what makes a product easy to use is the instructions that are included with the product that should include information such as how long you should wait on average for the water to be fully sanitized.

Speed of Purification

The speed of purification can be a dealbreaker in certain situations, for example, it will not make any big difference to a hobbyist camper that they need to wait a few hours for their water to be purified however if you are an emergency services operative on a rescue mission then it is important to be able to clean the water as quickly as possible in order to renourish the injured.

Potential of Leftover Taste and Smell

Although pretty much all manufacturers of water purification tablets claim that their products have no aftertaste or odor left over after they have been used in the water in reality in the majority of the cases there is a small change of flavor and potentially an odor lingering around.

Use by Date

The use-by date is very important especially if you are not someone that is going to be out hiking or camping every month, the longer the use-by date the more time you have to find the right opportunities to use the products without feeling the pressure of using it up just for the sake of it.

Thankfully all water purification tablets have a very long shelf life as long as they are stored properly.

Overall Effectiveness

Finally one of the biggest factors is the overall effectiveness of the product that you are using or deciding to purchase, not all water purification products are able to deal with all types of menacing microorganisms that are polluting your drinking water.

The Major Types of Water Purification Tablets

Tablets That Are Based Around Chlorine

A popular chemical that is frequently used to sanitize swimming pools, although products using this ingredient are affordable there is one major drawback to this product which is that after it has been used to purify your drinking water it will leave the well-known taste of chlorine which is not enjoyable, this can be reduced a bit by opening the lid of the bottle allowing the water to evaporate.

However, it will only weaken the taste and not permanently remove it. Additionally, it is a fairly weak chemical and it is not able to deal with more dangerous organisms found in your drinking what such as Cryptosporidium.

Tablets That Are Based Around Iodine

Tablets That Are Based Around Chlorine Dioxide

Chlorine Dioxide is often seen as the most effective way to treat dirty water, although it is effective it is important to keep in mind that it takes much longer than the other two major types of water purification tablets.

However, it is all about staying prepared and patient with the longer that you wait the higher the chance of all the organisms that can make you ill are being eradicated from your drinking water. Chlorine Dioxide is even able to kill parasites such as Cryptosporidium.

Which One Is the Best?

Overall Chlorine Dioxide is the best option as it is able to do its job properly even if it can take a few hours. What makes it the clear winner out of the other two chemicals, Iodine and Chlorine are that it pose a health risk to the individuals that consume.

For example, pregnant women should not women consume Chlorine and Iodine as well as the additional risk of consistent use of Iodine causing other health complications.
