Water purification / disinfection tablets

What are water purification tablets?

Water purification tablets are a compact means of treating drinking water while hiking, traveling, fishing, or in field conditions. These tablets are chemical agents that, when dissolved in water, destroy fungi, viruses, and other pathogenic bacteria. 

How do water purification tablets work?

After dissolving, the active ingredient reduces the number of microbes in the water. The Centers for Disease Control and Prevention advise treating water if its safety is uncertain, and for cloudy water, to filter it first. Boiling remains the best method, and disinfection is a good field option for obtaining safe water. Along with gas stoves, such products are often included in an expedition kit.

Why is it necessary to disinfect water before consumption?

Unsafe water can contain microbes and cause problems not only when drinking, but also when preparing food, washing vegetables, or brushing teeth. Water purification tablets and water disinfection tablets are not taken as a precaution, but when the source is questionable or there is no access to safe drinking water.

When are water disinfection tablets used?

They are taken for hiking, trips, fishing, by military personnel, for long expeditions, and in field conditions. Like sleeping pads and mats, they often seem like a minor item, but they take up no space and can be very helpful. Flash Army offers individual Aquatabs tablets in several formats and dosages.

How to choose water purification tablets?

When choosing water purification tablets, you should consider the intended use, dosage, water volume, and manufacturer's instructions. In this category, you will find several Aquatabs options in different dosages, so water tablets can be selected for various container volumes.

For example, for Aquatabs 167 mg, 1 tablet is specified for 25 liters of water and a 30-minute waiting time, but parameters may differ for other options. Along with travel coffee makers and other equipment, it's best to choose the format that suits your specific scenario.

What to check before buying:

  • tablet type;
  • water volume per 1 tablet;
  • waiting time after dissolving;
  • packaging format;
  • storage conditions.

Frequently asked questions about products in this category Water purification / disinfection tablets

Water purification tablets are small tablets for disinfecting water on the go, hiking, on duty, or during emergencies. They are added to water to reduce the risk of infection from bacteria and some other microorganisms. This is not a filter or a magic pill for any dirty water: it does not remove silt, sand, fuel, or chemical impurities.
Water purification tablets are used when there is no normal access to guaranteed safe drinking water. This can be a hike, camping, field trip, military service, an evacuation kit, or a supply in case of water supply interruptions. They take up minimal space, do not require electricity, and help provide a backup where boiling is not always possible.
The tablet dissolves in water and releases an active substance that acts on microorganisms. In chlorine-containing tablets, this is active chlorine; in other types of products, it is chlorine dioxide or iodine. Water treated with a tablet should not be consumed immediately: it needs time for the agent to work. The exact waiting time and the volume of water a tablet is designed for should always be checked in the instructions for the specific package.
The most common tablets are based on chlorine, chlorine dioxide, and iodine. Chlorine-containing options are common in tourist and emergency kits because they are easy to use and well-suited for basic disinfection. Chlorine dioxide is often used for more complex conditions, but it also requires contact time with water. Iodine-containing tablets are used more cautiously because they are not suitable for everyone and can noticeably alter the taste.
Water purification tablets are made from chlorine compounds, chlorine dioxide, or iodine. Aquatabs tablets use NaDCC — sodium dichloroisocyanurate. When dissolved, this substance releases active chlorine. Therefore, it is important not to break the dosage at random: a small tablet and a large tablet may be designed for completely different volumes of water.
Water purification tablets can work well against many bacteria and some viruses if the water is clear enough, the dosage is correct, and the required time is observed. However, chemical disinfection works less effectively against some parasites, especially in cold or turbid water. If the water is visibly dirty, it is best to let it settle or filter it first, and only then add the tablet.
In field conditions, visible dirt is removed first: water is decanted, passed through a cloth or filter, if possible. Then, a tablet is added to the volume specified by the manufacturer, the container is closed, and the required time is awaited. Do not use tablets without calculating the volume. If the product is designed for one volume, but there is more water, the result may be weaker than expected.
Water purification tablets in Ukraine cost approximately from UAH 40 for a small pack. Larger sets, higher-dose tablets, and packaging for treating significant volumes of water cost more. The price is influenced by the active ingredient, the number of tablets, dosage, brand, and the volume of water the package is designed to treat.
Water purification tablets should be added to your kit not after the first water problem, but in advance — along with a bottle, flask, or small filter. At Flash Army, such products are suitable for an emergency backpack, field kit, camping, travel, and as a reserve in case of water supply interruptions. A small package is enough for one person, but for a group, it's better to calculate the reserve by liters, because the number of tablets alone does not show how much water can actually be treated.
