Bad air in the car: Almost 40% of the drivers are ignorant!

With spring, a challenging time begins for many allergy sufferers. Drivers in particular should be aware that air quality in the car plays a crucial role. According to a YouGov survey on behalf of Ebay Motors from May 5th to 7th, 2025, in which 2057 people took part, 39% of vehicles in Germany have an outdated or contaminated interior air filter. This information was provided by the Schwäbischen

dr. Bernhard Junge-Hülsing warns of the health risks that can arise from poor interior air. Clogged filters can cause respiratory tract irritation and immune reactions. An alarming knowledge of the survey is that only 33% of the car owners have changed their interior air filter in the past two years. In addition, a third of the respondents have not changed the pollen filter for more than two years, while almost a further third could not provide any information on changing the filter.

causes of poor interior air

The interior air can be loaded from different sources by various pollutants. According to the Federal Health Center, there are chemical substances that are released in particular for renovations or by furniture and cleaning products. This includes substances such as formaldehyde and asbestos that are harmful to health. Also exhaust gases and fine dust from the outside air contaminate the interior air, especially in ground floor apartments near lively roads.

Allergens such as house dust mites and animal hair also play a role and can cause allergies and respiratory diseases. In addition, the formation of mold is promoted if the air humidity is too high. These factors make a significant contribution to deteriorating the air quality that is stressful for many people. Information on the various pollutants can be read in Federal Health sheet

consequences of poor air quality

Ignorance compared to air quality in the car and the associated risks can have serious consequences. In severe cases, poorly treated respiratory diseases can lead to other health problems, such as a stroke that is often caused by a clot. The timely treatment of a stroke can be crucial for the rescue of life and the limitation of consequential damage. It is important that patients are brought to a clinic at an early stage in order to apply suitable treatment methods such as thrombolysis or thrombectomy. Information on stroke treatment can be found on the website of the Federal Health Center here .

Due to the information from Ebay Motors, every car owner should think about changing their interior air filter regularly. Around 67% of those surveyed do not change their filters regularly or do not know when it was last changed. Over 18% of the interviewees even stated that their pollen filter is older than 10 years or has never been changed. Regular maintenance, especially with high -performance filters such as HEPA, can help to significantly improve the air quality in the car and thus protect the health of the occupants.
