Main highlights

Versatile: perfect for water disinfection when travelling in countries without safe drinking water supply, outdoor activities, camping, for water rowers and for emergency/prepper equipment. Even in the emergency backpack, a pack of our water treatment tablets must not be missing.
Safe drinking water treatment: our water disinfection tablets (also called water treatment tablets) based on chlorine dioxide effectively remove bacteria, viruses, giardia, cryptosporidia and other parasites from pipe, storage and river water and make it drinkable. The tablets are 2.6 times more efficient and safer than chlorine tablets.
N-107920. Please note: use biocidal products carefully. Always read the label and product information before use.
Long shelf life: our water purification tablets have a shelf life of up to 2 years from manufacture and are therefore a reliable solution for any trip or for preparing for emergencies (blackout, power failure, etc.).
Important note: for chlorine dioxide tablets to work, a certain amount of active ingredient must also be included. This is the only way to ensure that the tablets can be used for different applications. In clean water (e.g. German tap water), a clear side taste and odour is contained. However, when using contaminated water, this is minimised.
Effective against: Chlorine dioxide tablets are an effective means of destroying viruses and bacteria, including the causative agents of cholera, E-coli, giardia, hepatitis A and travel diarrhea. In just 10 minutes, you can prepare and disinfect your water on the go.
Easy to use: simply add 1 tablet to 1 litre of water, shake well and wait for the tablet to dissolve. No additional devices or outdoor water filters are necessary. The disinfection tablets can not only be used for drinking water, they can also be used to disinfect water filters.
