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.

The application of the textile impregnation is extremely simple and only takes a few minutes. The product can either be sprayed onor applied with a brush or sponge. The impregnation is suitable for outdoor and functional textiles such as jackets, pants, workwear and rucksacks. Heat activation is not necessary, the fixation can take place at room temperature. The protective effect is very effective. The product creates a water and dirt repellent property. The product is also abrasion-resistant, as the waxes it contains fuse with the textile fibers during drying. This effectively protects against wear and extends the service life. At the same time, the breathability of the textiles is retained. In addition, the product is transparent , water-based, fragrance-free and free from harmful perfluorocarbons. Very good skin compatibility has also been confirmed.
