Water Purification Tablets Versus Drops

Humanitarians often find themselves in places with no access to potable water. Whether you are part of an emergency response team, deploy to a remote area, or elsewhere, water purification may be vital for your well-being. There are many tools for this, but water purification tablets and drops are some of the most popular options.

Types of water purification tablets and drops

There are several different types of water, purification tablets, and drops. Here are some of the most popular options:

Iodine: iodine water purification comes in tablets, drops, and crystals. These kill bacteria, viruses, and giardia. The product takes 30-50 minutes to work, and it is best to use in warmer water. The two downsides of iodine water purification are unpleasant flavor and color, and the fact that some people may be allergic.

Chlorine: chlorine is available in liquid and tablet form. It also kills bacteria, viruses, and giardia. Once introduced in the water, it takes about 30-45 minutes to purify it. Chlorine may also leave an unpleasant smell and is unhealthy over more extended periods of consumption.

Chlorine dioxide: a great alternative to chlorine is chlorine dioxide. It is the most potent water purification tablet on the list but takes about 4 hours to work. The great thing is that it does alter the taste of water and has fewer side effects than chlorine.

Sodium Dichloroisocyanurate (NaDCC): NaDCC tablets react with water to create what is called free chlorine. You don’t get the taste or odor of chlorine, and it is safe to consume. NaDCC tablets are safe to use against bacteria, cysts, and germs.

Pros of water purification tablets

Water purification tablets are a great solution when you don’t have access to clean drinking water for a short period. They are convenient to use, work quickly, and kills most bacteria and viruses. They are also lightweight and easy to transport. Further, water purification tablets are inexpensive and have a long shelf-life.

In the case of chlorine, tablets tend to work better than liquid. That’s because they have effervescent salts, which aid in purifying water. Meanwhile, chlorine dioxide is only available in tablet form, and it is the most potent water purification tablet on the market.

Cons of water purification tablets

Long-term use of water purification tablets may be harmful to one’s health. For example, people with thyroid issues should not use too many iodine purification tablets. Also, certain tablets can cause allergies. If you are pregnant, water purification tablets may be harmful, so you need to check with your doctor before using them.

So, what’s better: drops or tablets?

The short answer is, it doesn’t matter. The reality is that it depends on your preference or what is more readily available. Liquids may be harder to transport, as they may spill. However, one container may be enough for several uses, while you will need various tablets for multiple applications.

Also, you should consider the source of water that you will be using to decide which method of water purification you need. For example, some water sources might have a lot of organic matter or potential viruses. Other water sources may contain heavy metals, which require a more sophisticated filtration system.

The key is to stay safe while you are in remote areas. If you anticipate that you might travel to places without safe potable water, always carry water purification tablets or drops with you. It’s best to test them before you use them in a remote area, to make sure you are not allergic.
