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.

ThoMar
Dehumidifier

The ThoMar OHG dehumidifier is a highly effective product that has been specially developed to protect against misted-up windows and moisture damage in the car. The silica gel pads it contains remove moisture from the vehicle interior and thus not only ensure dry windows, but also prevent mold, rust and unpleasant odors. The high absorption capacity and long duration of action of the silica gel make the dehumidifier particularly effective. It can also be regenerated and reused, making it a sustainable solution. The fact that ThoMar products are manufactured in Germany and regularly certified to ISO 9001 underlines the high product quality.

Advantages

✅ High absorption capacity
Regenerable and reusable
✅ Very effective
✅ Made in Germany

Disadvantages

❌ None

*The maximum score is 100 points

The practical test of the ThoMar de humidifier has shown that the manufacturer largely lives up to its advertising promises. The effectiveness of the dehumidifier is very good, as it effectively reduces the humidity in the car and thus ensures dry windows and good air quality. Despite its effectiveness , the ThoMar airdry de humidifier takes up very little space, making it particularly practical and space-saving .

In terms of durability, it was found that a cushion can absorb up to 300 ml of water and regeneration is required after approx. 2 months. Regeneration can be carried out using various methods such as microwave, oven, heating or sunlight , whereby the duration varies depending on the shape.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it?

Rating cut4.3 out of 5.0 on Amazon65 points

Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.3 stars. The fact that it attracts moisture and keeps the car dry is positively emphasized, which is highly appreciated by customers. The fact that the product works as desired is also praised. On the negative side, the fact that it is virtually ineffective is occasionally criticized. In our practical test, we were able to confirm that the dehumidifier effectively attracts moisture and keeps the car dry.

Prices of up to €23.90/pc are charged on the internet for equivalent products. Very inexpensive products are available from as little as €9.98/pc. The dehumidifier from ThoMar OHG is therefore currently in the lower price segment with a price of €9.98/pc. For the quality and performance received, the price-performance ratio is very good.
