How can I improve the air quality in my Audi 80?

I have noticed that the air quality in my Audi 80 is not as good as it used to be. I would like to know some tips or recommendations on how to improve it.

Consider replacing your cabin air filter. This filter traps dust, pollen, and other airborne particles to help improve air quality. You can usually find instructions on how to replace it in the owner's manual.

Regularly clean and disinfect your air vents and ducts. Over time, these can accumulate dust and bacteria, which can compromise air quality. You can use a gentle cleaner and a cloth or brush to clean them thoroughly.

Invest in an air purifier for your car. These devices use filters and ionizers to remove contaminants from the air. Just make sure to choose one with a HEPA filter that is suitable for use in vehicles.
