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.

maxprime®
Radiator brush for flat radiators

The maxprime® radiator brush is a practical tool to increase the efficiency of your heating system and at the same time ensure better indoor air. The radiator brush has been specially developed to remove dirt from the inside of radiators.
With the cleaning brush made of real goat hair , dirt particles are not only loosened, the soft bristles hold dirt particles better than synthetic bristles. The brush is very flexible so that dirt can also be effectively removed from hard-to-reach corners. Brushing also reduces the amount of dust in the room. The solid hardwood handle gives the brush stability and makes it easier to handle. With an impressive length of 120 cm, it is perfectly sized to clean most radiators. But the benefits of the radiator brush go even further. A clean radiator can work up to 20 % more efficiently, which has a positive effect on heating costs. As the stainless steel wire is very flexible and long, you can reach the most remote and narrowest gaps in the home.

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

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

The practical test of the maxprime® radiator brush showed a predominantly positive match with the advertised properties. The cleaning success was evident even with stubborn dirt. The human hair bristles proved to be particularly effective and flexible, and the brush itself was pliable.
Application was effortless and time-saving. It was particularly impressive that the heating fins could be reached without removing the upper cover plate.
The minimal amount of work required to use the radiator brush is remarkable.
The goat hair is soft so that the radiator cannot be scratched. However, in some cases, especially with special slats, a firmer brush with bristles may be an advantage.
The 120 cm length of the brush is suitable for most rad iators and provided sufficient reach. The flexible rod allowed for space-saving storage. However, it turned out that forming a straight line can be a bit of a challenge due to its flexibility.
Overall, our practical test confirmed most of the manufacturer’s advertising promises in terms of cleaning effect, application, workload and material quality. However, the adaptation to specific types of slats and the possible difficulties in forming a straight line must be taken into account.

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? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.3 stars, often complaining that the radiator brush is fluffy. Many customers like the fact that the radiator brush fits very well in the flat radiator heaters. In our practical test, we were able to confirm that this is an exceptionally high-quality product.

Prices of up to €14 are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €9 . The radiator brush from maxprime® is therefore currently in the lower price segment with a price of €9.98. For the quality and performance received, the price-performance ratio is good.
