About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

They are also particularly recommended in the event of natural and environmental disasters to ensure that clean drinking water is available at all times.

Both the cardboard and the aluminum packaging show occasional dents and scratches, but the protection of the tablets is guaranteed by the sturdy aluminum packaging.

ℹ️ Our practical test has the highest relevance and therefore weighting. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

Wasserfeld water sterilization tablets are a chemical alternative to drinking water treatment. The active ingredients sodium hydrogen sulphate and sodium chloride turn any water into drinking water within 30 minutes. For your own safety, you should drink water that is already as clean as possible before the tablet is added, e.g. water from running water. Water that smells unpleasant or contains dead animals is not suitable.
The tablets are easy and uncomplicated to use. One tablet is sufficient for up to 100 liters of drinking water disinfection, but can also be used for less than 100 liters. It is dissolved in the water and should be left to stand for at least 30 minutes to achieve a sufficient effect. The resulting disinfectant solution can then be used to purify the drinking water. The purified water is odorless and tasteless and can be drunk without hesitation.
A positive feature is the individual packaging of the tablets, which guarantees a shelf life of 10 years for unopened tablets and enableseasy storage when traveling.

Overall, the water purification tablets scored very well, are a good alternative to natural water purification and are therefore a product worth recommending.
