The first impression of the Cosi Car dehumidifier is extremely positive. The product is delivered in a classic shipping box, which is also packed in a separate cardboard box. This ensures optimum product protection , as shipping paper has been inserted to protect the contents. The sustainability of the packaging is particularly noteworthy, as only recyclable, renewable materials such as paper and cardboard were used for the outer packaging.

When the packaging is opened, the contents are complete and in perfect condition. In addition to the dehumidifier , a practical ice scraper is also included. The enclosed instructions for use are clearly written and in German, which makes the product easier to use.

The Cosi Car dehumidifier impresses with its visual appearance alone. The high-quality workmanship is clearly visible and conveys a robust and durable impression. On a positive note, the dehumidifier does not smell of plastic or chemicals, which indicates that the materials have been carefully selected.

The stability of the product is also very good. The Cosi Car dehumidifier appears solid and stable, which enables reliable use. Although there is no specific information on the sustainability of the product, the high-quality workmanship suggests that high-quality materials were used in its manufacture.

Another positive aspect is the packaging of the dehumidifier, which is also suitable as a gift. The appealing design and high-quality packaging make the Cosi Car de humidifier an attractive gift for car enthusiasts or people who value a pleasant indoor climate.

*The maximum score is 100 points

Our practical test of the car dehumidifying cushion has shown that the manufacturer keeps its advertising promises in several areas. The effectiveness of the cushion in reducing moisture is very good. A significant amount of moisture was removed from the car, leading to a noticeable improvement in the indoor climate.

Another positive aspect is the low space requirement of the dehumidifying cushion. It hardly takes up any space in the vehicle and does not impair visibility or other functions.

The cushion can be used for around two to three weeks, after which it needs to be dried . The cushion is equipped with a practical indicator that turns pink when it absorbs moisture. This makes it easier to monitor and clearly indicates when the pillow needs to be dried. Drying can be done either in the microwave or on the heater , making the process easy and convenient.

In addition, the dehumidifying pad was also convincing in terms of odour neutralization . Unpleasant odors in the car were effectively reduced, which contributed to a more pleasant driving experience.

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.
