last updated Aug 19, 2019

How important do you think it is to have access to clean, purified water at all times? Let that question soak in for a second as it identifies what this buying guide is all about. The reality is whether you are out camping or even if an emergency presents itself, there may not always be fresh water available.

However, you can change that with water purification tablets. For the record, there are all sorts of water filter systems and water purifiers available. But, for this guide, the focus is strictly on water purification tablets (not drops or powders, either).

The best tablets will not only remove all sorts of bacteria from the water, but they will do so without adding unpleasant flavoring. This is just scratching the surface, though, so let’s get this thing rolling.

Pros:

They can remove loads of bacteria

It is an EPA registered brand

Each tablet comes in its own package

Cons:

Each tablet only purifies one liter of water

These are technically known as chlorine dioxide tablets and they are some of the most efficient in the world today. They are also individually sealed and this allows them to have a longer shelf life.

Read more

Effectiveness

The chlorine dioxide that is released from these tablets allows them to kill just about anything. They can remove viruses, bacteria, crypto, and giardia from any water source.

Flavor

Chlorine dioxide is the same substance that is used in municipal drinking water plants. What this means is you can expect your water to taste insanely good.

Purity

In addition to the fact that these tablets are EPA registered as a microbiological water purifier, they are also individually sealed. You can open them when you are ready.

Value

Alright, so each tablet is only going to purify one liter of water. Also, there are 30 tablets in total. So, if you can do basic math, it means that you can purify 30 liters of water in total.

Convenience

The amount of time you need to wait depends on what you are trying to remove from your water. For basic bacteria and viruses, only five minutes will be necessary. However, for really bag crypto, you may need to wait around four hours.

Overall

In spite of the fact that these tablets can only purify a limited amount of water, they work as well as any other model out there. They also produce wonderful flavor, which is also important.

Pros:

There is not a long wait time

Used by several relief organizations

Effective against all types of bacteria

Cons:

The PA Plus tablets could work better

As you can see from the photos, this actually comes with two different bottles. They need to be used in conjunction with one another and, when done properly, will result in clean and fresh drinking water.

Read more

Effectiveness

Firstly, you treat the water with the Potable Aqua tablets and this will rid it from viruses, bacteria, and cysts (not crypto, though). From there, you then use the PA Plus tablets to neutralize the iodine aftertaste.

Flavor

Even though the PA Plus tablets are supposed to neutralize the iodine aftertaste of the Potable Aqua tablets, a few buyers have noted that an iodine-type taste can still be noticed.

Purity

Because these are used by relief and military organizations all around the world, it is easy to put your trust in this brand.

Value

It actually takes two tablets to treat just one liter of water. It then requires two PA Plus tablets to treat the water. And, also, there are 50 tablets in each bottle.

Convenience

In total, the entire process of utilizing these tablets is going to take around 30 minutes (probably a few minutes more).

Overall

Sure, there are options that offer superior value. But, in regard to its effectiveness, few brands do it better. The PA Plus tablets could have worked slightly better, though, admittedly.

Purity

NaDCC is an EPA approved ingredient so you know you can trust it. As for the tablets themselves, they can be stored in a heat-sealed, four-layer thick Mylar pouch for optimal protection.

Value

As noted, these are a bit more potent than other brands. One tablet is going to effectively treat up to five liters of water. And, with 100 tablets in total, you can purify up to 500 liters of water.

Pros:

Sports NSF 60 certification

Messy if the packages get wet

As was noted earlier, Aquatabs is one of the leading brands when it comes to water purification tablets. These are individually sealed and will last for quite a long time.

Read more

Effectiveness

Each of the tablets that you receive contains a concentrated dose of NaDCC. This allows them to remove all types of waterborne diseases such as cholera, typhoid, and dysentery.

Flavor

As noted by a few different reviewers, these tablets leave a slight aftertaste. However, it does not appear to be anything too appalling so that is a good thing.

Purity

Indeed, each of the tablets has been individually sealed for maximum longevity. Additionally, these tablets also sport NSF 60 certification. Oh yeah, they are also used by the World Health Organization.

Value

One of these tablets is going to purify two quarts of water. When compared to other options, this is one of the better values out there.

Convenience

As with several other tablets on this list, these will have your water ready to consume within 30 minutes. The longer you wait, the better, though.

Overall

At the end of the day, you just can’t go wrong with Aquatabs. These water purification tablets will do wonders for you and are almost a necessity to tag along while camping or hiking.

Pros:

Designed to release chlorine dioxide

Effective against all types of bacteria

They are simple to use

Cons:

They require more time than other brands

Due to the fact that these next tablets release chlorine dioxide, they are proven to inactivate crypto cysts. That alone makes these an incredibly compelling option, quite frankly.

Read more

Effectiveness

As just mentioned, these are effective against crypto cysts. They are also effective against plenty of other bacteria and viruses (such as giardia and lamblia) as well.

Flavor

The only thing these are going to do, regarding the taste, enhances it. You will be left with no unpleasant aftertaste after drinking your water, count on it.

Purity

Past the fact that these tablets are individually packaged, they are designed to release chlorine dioxide. This is an EPA approved ingredient and is one of the best out there.

Value

For the record, there are options available for both 20 and 30 tablets. Now, either way, one tablet is going to be able to treat one quart of water. This is about normal, to be honest.

Convenience

Alright, so several of you are not going to like this. As opposed to others, these tablets require a four-hour wait time to treat the water effectively.

Overall

With tablets like these, you will need to allow them to perform their magic for a few hours. They work great, though, and have the advantage of being effective against crypto cysts.

Pros:

Meets EPA water purifier test standards

20 and 30-count options are available

Effective against all types all micro-organisms

Cons:

They can be a pain to open

A long treatment time is required

As you can see by their second appearance on this list, Katadyn gear is another highly trusted and reputable brand. Their MP1 Tablets meet EPA standards for water purification and that really says it all.

Read more

Effectiveness

These water purifying tablets are effective against all micro-organisms. They will attack whatever is currently present in the water and that you can take the bank.

Flavor

As with some of the other best brands out there, you will be provided with fresh-tasting water after using these tablets. You can expect there to be no lingering aftertastes.

Purity

Again, one of the reasons this is such a trusted brand is because Katadyn is dedicated to making the most effective products possible. As such, their MP1 tablets are EPA approved.

Value

No matter which option you go with (either 20 or 30 tablets), each tablet has been pre-measured to treat one full liter of water.

Convenience

In addition to the fact that these are a bit of a pain to open, they require a four-hour treatment time. For sure, while great, this is not the most convenient brand out there.

Overall

Truthfully, about the only “issue” that prevents these tablets from being even higher on this list is the fact that they are not incredibly convenient to use. They get the job done with flying colors, however.

Pros:

Extremely potent

It only needs around 30 minutes to do its thing

It is effective against all types of bacteria

Cons:

Other brands are more reputable

What is utterly amazing is the fact that these tablets were engineered to purify up to 50 gallons of water. And, you only get 10 tablets. Do the math on that one.

Read more

Effectiveness

These suckers are effective against loads and loads of parasites and bacteria. This includes fungi mold, yeast, protozoa, mycoplasmas, and hydrophilic viruses.

Flavor

Though a slight odor may remain after these tablets do their job, it will not be anything that will affect the taste too much. And, these are designed with an effervescent additive to help eliminate the chlorine, in the first place.

Purity

What makes this somewhat sketchy is it is not as reputable as other brands. It has also been known to expire quicker than their 36-month shelf life would indicate.

Value

Yeah, in case you did not already figure it out, each tablet can purify five gallons of water. Clearly, this makes these tablets incredibly potent and more ideal for larger quantities of water.

Convenience

After you place a tablet into the water you want to be purified, you will need to wait around 30 minutes. After which, your water will be ready to go.

Overall

Yeah, this is better suited for those of you will need larger quantities of water. It is not the most reputable brand out there, though, so be aware of that.

Pros:

Keeps you from getting sick from untreated water

50 tablets are in each bottle

The PA Plus tablets will remove iodine flavoring

Cons:

The resulting water can still taste a little chalky

This is yet another time-tested option that has been proven to work. It also comes with PA Plus tablets to remove both coloring and iodine flavoring from your purified water.

Read more

Effectiveness

The combination of the main tablets and the PA Plus tablets do wonders in just about any water source out there. They do their job effectively against untreated water, let’s just say that.

Flavor

A few previous buyers have made mention of the fact that this can leave somewhat of a chalky taste to your water. It is nothing too drastic, however.

Purity

Indeed, this is a time-tested option that is both simple to use and also incredibly effective to use.

Value

Each bottle you get has 50 tablets. And, you will be required to use two tablets of each bottle to treat one quart of water. What this means is, in total, these bottles will treat up to 25 quarts of water.

Convenience

If you want the flavor of the water to be good, you will need to be patient. While the purifying process takes around 30 minutes, it takes extra time to remove the iodine taste afterward.

Overall

This is just another fantastic option from a long-list of them. It does not provide the best value but it gets the job done extremely well.

Pros:

It is iodine-based

It is proven to work against giardia

Fairly fast acting

Cons:

Not the most potent option

This is an iodine-based compound and while it does leave a slight aftertaste to your water, it is nothing too bad. And, it works incredibly well and just as directed.

Read more

Effectiveness

For sure, this is an excellent method for microbial extermination. It has also proven to be effective against giardia.

Flavor

You can expect there to be a slight aftertaste when using these tablets. Again, as noted, this aftertaste is not going to be anything unsettling enough to make the water undrinkable.

Purity

This is not a top-name brand but that is simply okay. The effectiveness makes up for it that is for sure.

Value

Let’s just address the elephant in the room; this is one of the least potent options on this list. The 50 tablets you are provided with will only treat up to 25 quarts of water.

Convenience

It is recommended that you wait around 30 minutes to allow the tablets to purify your water. But, honestly, the longer you wait the safer the water is going to be to drink.

Overall

While less potent than others, this is still an excellent option. Due to the potency, though, it is better served for emergency situations and such.

Criteria Used for Evaluation

Effectiveness

What you need to analyze is the main active ingredient as this will dictate performance.

The best way to determine the effectiveness of any given tablet out there is to assess what the main active ingredient is. Generally speaking, this active ingredient is either going to be iodine, NaDCC (a form of chlorine), or chlorine dioxide. All three of them are commonly used for water purification.

Speaking for iodine, this is a chemical compound that is incredibly effective when it comes to eradicating parasites, viruses, and bacteria. Also, it has been known to be effective against giardia (when allowed to sit for at least 50 minutes) but not crypto. Of course, you will also commonly see NaDCC.

As noted, this is just a form of chlorine, but it is often seen in water purification tablets. While chlorine is another agent that has been known to be ineffective against crypto, it destroys many other micro-organisms. It naturally can’t combat crypto because of the parasite’s protective shell.

However, you then have chlorine dioxide tablets, and these are probably the most powerful. Unlike iodine and chlorine, chlorine dioxide can kill both giardia and crypto. So, if you want to kill as many micro-organisms as possible, go with chlorine dioxide. The only downside, as you will find out, is these tablets will take longer to purify your water thoroughly.

Taste

Ironically, this section is more based on the importance of tablets not adding flavor.

Another reason why it is vital to pay attention to the active ingredient is that it will play a massive role in this next section. Clean and purified water is not only safer but will also result in better-tasting water. However, different active ingredients can yield differing flavors.

For instance, with iodine tablets, you may notice a slight taste of iodine. Thankfully, as you saw on this list, there are specific tablets that can combat the added iodine flavoring. While this will increase the wait time, it will be well worth it.

As for chlorine, it is not as if adding these tablets will make your water taste like pool water. At the same time, you may notice a faint smell of chlorine (as that is not uncommon). But, once again, this is where chlorine dioxide tablets reign supreme.

In addition to having fewer side effects, these tablets will also not alter the taste of your water negatively in the slightest. Then again, all three of these active ingredients typically will not yield unbearably tasting water, so be aware of that.

But, it is never a bad idea to glance through user feedback to see what others have had to say about a particular brand.

Product Purity

There are some important things to keep in mind for this section so pay close attention.

There are many levels to this section, but the first is whether or not the brand you go with is currently used by military organizations and professional agencies around the world. While this is far from mandatory, the trust you can place in brands like this is almost unmatched.

If you know that significant agencies (such as the World Health Organization) and militaries are using a specific brand that you buy, you can take comfort in knowing that it is most likely extraordinarily effective and safe.

Of course, maybe you are someone who needs to know that the water purification tablets you buy are registered by the Environmental Protection Agency (EPA). That is entirely fair as no one is going to blame you. Anyway, indeed, you will see some brands sport EPA registration, and this means that the tablets were rigorously tested beforehand.

Oh, and one last thing, it is also not a bad idea to look for tablets that are individually sealed. This way, until you open them, if stored properly, they will be good for years to come.

Value

How much water do you think you will need to be purified? Answering that question will help you figure this section out.

Alright, so now it is time to dive into some mathematics (everyone’s favorite subject). Let’s get the easy part out of the way. You first need to assess how many tablets are included with your purchase. Some sellers will consist of 20, some 50, others 100, etc. This is the first number you want to get in your head.

Now, moving on, you need to figure out how much water one of those tablets will purify. Most sellers will provide this information to you on either the packaging or their official product page. Typically, most water tablets will purify around one to two liters of water per tablet. Also, as a side note, one quart is roughly one liter (you will sometimes see them labeled in quarts).

Alright, with that out of the way, let’s put these numbers in perspective. Let’s look at the most common size for a commercial water bottle (which is 16.9 ounces). Do you have that picture in your head? 16.9 ounces works out to roughly half-a-liter. So, if you bought tablets that each purified one liter of water, one of them would be able to clean two standard water bottles fo hiking.

This is to give you an idea of what you can expect. After all, the potency you need will depend on how much water you will be drinking and using.

Ease of Use

While all brands will be fairly easy to use, some of them will require longer waiting times.

What is nice about water purification tablets, in general, is that they are all reasonably easy to use and convenient. For the most part, they all work in the same manner as you need to drop them into the specified amount of water that is required.

However, what will be different from brand to brand is the waiting time for the tablets. This is where iodine and chlorine have an advantage. Both of these ingredients only need around 30 minutes to purify water thoroughly. Then again, if giardia is present, then iodine and chlorine tablets will need to sit for 15 to 20 extra minutes.

For chlorine dioxide tablets, however, the wait time is significantly longer. Typically, it will take these tablets at least four hours to purify completely. Then again, these will rid waters of crypto so it makes sense that it will need longer to perform their magic. For most of you, this waiting time is going to be worth it; though it does depend on the severity of the water, you need purifying.

Effectiveness

The most important thing for you to do is to familiarize yourself with iodine, chlorine, and chlorine dioxide. From brand to brand, typically, one of these three active ingredients will be utilized. And, quite honestly, every one of them are effective in their own right. But, if you are looking to drink the cleanest and purest water possible, go with chlorine dioxide.

Taste

Unless you want to drink flavored water (we are not talking about intended flavored water, either) you should only buy tablets that do not negatively affect the flavor of the water. And, this goes back to assessing what active ingredient is utilized in the brand that you buy. Of course, you can also look through user feedback to see what others have had to say.

Product Purity

You may be asking, what makes water tablets pure? Well, as will be discussed, there are a few ways you can go about this section. Firstly, you can look at how reputable the brand is and if major agencies and such utilize it. Seeing if the brand is EPA approved is also not a bad thing. Oh, and you can also ensure that the tablets themselves are individually sealed for maximum freshness.

Frequently Asked Questions

q: What happens if you swallow the tablets?

a:

Alright, so you need to make sure that you allow the tablets to disintegrate into the water entirely. If you abide by the guidelines set out by the manufacturer, then you should be fine. But, let’s say that you somehow manage to swallow one of the tablets (or your child accidentally does).

Well, firstly, you need to start drinking plenty of water. Then, you should probably get ahold of a doctor or some sort of a medical specialist to see what they recommend you to do.

q: Can you still use broken tablets?

a:

Look, nobody is perfect, and accidents happen to everyone. In the case that one of your tablets breaks into two or more pieces, there is no reason to fret. You are going to move forward as you normally would.

The reality is the tablets are going to disintegrate into the water anyway. So, it does not matter if they go in pieces or not. Just ensure that you throw all the parts that broke into the water and you will be good to go.

q: Do you need to worry about expiration dates?

a:

There are some brands out there that will come with expiration dates, and others will not. If they do then, clearly, they will expire on the specified time. But, some brands will be EPA registered and will not require an expiration date.

Either way, it is in your best interest to properly store your tablets. To maximize the shelf life of them, they should be stored in cool and dry locations. Keep them away from humid environments.

q: Can’t you just boil the water instead?

a:

There is no denying that one of the most effective and efficient ways to kill micro-organisms is to bring water to a rapid boil. This may be even more effective than using water purification tablets.

While we are not going to debate between the two different water purifying methods, it is worth pointing out that boiling water can often be the more costly option. After all, if you are in an emergency situation or out hiking, you will need a fuel source to boil the water. That will not be an issue with tablets.

q: Can they be repackaged into different containers?

a:

One of the primary reasons why most water purification tablets are so meticulously packaged is that they should not be exposed to the outside air until they are ready to be used. It all comes down to their properties as they will degrade quickly if exposed to moisture.

As such, it is recommended to avoid repackaging them. You will be much better off leaving them in their sealed packaging. When done so, after all, most tablets will still be suitable for a few years down the road.

q: Should you dissolve them with warm water?

a:

It all depends on how quickly you want your water to be purified. If you are very impatient and are looking for a quicker way to get around the process, you could use warm water. Indeed, the tablets are going to dissolve faster in such water.

Worth noting, however, is you should not do so in hot water. Ensure that the water you are using is nothing warmer than lukewarm. Of course, remember, waiting an extra 10 minutes to kill off as many micro-organisms as possible will be worth it.
