What Are Water Purification Tablets?

When you think of purifying water, you probably think of a pump, a filter, or even boiling your water. But did you know that you can purify your water with a water purifying tablet? These tablets are perfectly sized to slip into your emergency kit or backpack, and they can provide you with a quick way to purify water without having to carry around extra equipment.

These tablets were first developed by the U.S. Army and have since been used to help soldiers in the field and hikers in the wild. Many hikers prefer water purification tablets over other water treatment methods, such as filtration systems, because they are small, lightweight, and easy to use.

These are small round tablets that are made from a special type of clay. You drop them into your water bottle or another container of water and let them sit there for about an hour. When that’s done, you can drink the water and know that it’s safe to do so.

How do they work?

Water purification tablets are a great, portable way to keep your water safe in the wilderness. They are small and lightweight and can be stored practically anywhere. But how do they work? There is a little bit of science behind water purification tablets. The tablets contain iodine, which kills the microbes that live in water and cause illness.

In most cases, they work by using a method called adsorption to remove harmful bacteria and heavy metals from the water. Heavy metals, for example, are usually found in polluted water and can be very dangerous if ingested. By using a water purification tablet, you can remove these metals from your drinking water so that you will be much safer to drink it.

Do these work for all kinds of water?

The short answer is “yes.” Most water purification tablets are effective for all types of water, including quite a few that you might not think about. For example, most of them will remove chlorine and iodine from your water, which means they can also remove it from your tap water or the water at the end of your garden hose.

What germs, bacteria, and viruses do they kill?

Water purification tablets may not be able to kill every single germ and virus since there are so many different ones out there, but they can remove most of them. They have been known to work very well against bacteria like E. coli, Giardia, and Dysentery. They also remove viruses such as Polio and Hepatitis A from water.

Most tablets kill a wide range of germs, bacteria, and viruses. One recent study found that an elixir of silver, copper, and zinc kills more than 99.999% of the most common waterborne bacteria and viruses. 

The EPA says a water purifier should kill at least 99.99% of bacteria. The tablets can remove giardia, which is the most common protozoan parasite found in the United States. However, “It’s important to remember that there are millions of different bacteria and viruses in the water in each state and that water treatment technologies have not yet developed to treat all of them.

Do Tablets Really Purify Water?

Water purification tablets, commonly known as water tabs can be used to kill dangerous bacteria in case of an emergency. Water tabs are highly compact and can easily fit into a backpack. They are light-weighted and are considered to be cheaper than the other purifying alternatives such as the water filter and bottled water.

However, a person should always keep in mind that not all purification tablets take care of viral particles. Staying safe while backpacking is every outdoor adventurer’s priority.

While water purification tablets aren’t exactly the most exciting topic in the world, they’re a necessity for those who hate the taste of iodine or want to avoid the hassle of boiling all water.

Unfortunately, the effectiveness of tablets can vary widely, so we thought we’d give you a rundown of what we found after filtering through the research. (To be clear, we’re talking about the tablets that kill bacteria and viruses, not the ones that just remove debris and chemicals.)

Why Should You Use A Water Purification Tablet?

Many people like the idea of hiking because it’s a fun way to enjoy the great outdoors. However, it can also be dangerous, especially without the right equipment. One danger is that it’s easy to drink contaminated water when you’re out hiking, which can lead to serious health problems.

Water from rivers and lakes often has harmful bacteria and heavy metals in it, and water that looks clean can still be contaminated with harmful substances. The best way to prevent this is by filtering the water before you drink it.

  • Can cause water to taste bad

How To Choose Which Purification Tablet Is Best For You?

When you boil it down, choosing the correct water purification tablet can be broken down to a few factors: quality, quantity, and cost. (Well, that’s a nice, clean list.) While there are other factors to consider as well, such as the taste of the water or the ease of use, those three biggies are usually the most important. !

The first factor is quality.

The most important factor is how well they remove unwanted bacteria from the water – do they work well?

Why spend money on a product that doesn’t do what you want it to do? The bottom line is you want quality first.

The second factor is quantity.

Choosing the right amount of purification tablets for you and your family can have a huge impact on cost. The more purification tablets you buy, the better value that gets spread out among the entire pack. And of course, the more tablets you buy, the longer they’ll last, and therefore the better value you get.

The third factor is cost.

While you don’t want to skimp on quality, it is possible to get both high quality at a reasonable price.

Okay, now that you know what to look for in a water purification tablet, let’s take a look at some options.
