Cabin air filters put the joy back into driving

Cabin air filter against pollen by MANN-FILTER

Air flows into a vehicle at a volume of up to 540,000 litres per hour through the ventilation ducts. Imagine the amount of dirt and dust that comes with it. Now picture that entering your lungs. Not a pretty picture. In fact, the air inside a car contains around five times more exhaust gases, pollutants and allergens than outside air. Vehicle cabin air filters remove up to 90% of even the tiniest  harmful particulates (up to 1µm, in size)  creating a barrier between passengers and the incoming air.

A MANN-FILTER cabin air filter can separate tiny particulates almost 100% – the damaging micro-organisms contained in pollen, exhaust fumes, smoke, fossil fuel emissions and gas droplets. Some of these are smaller than 3% of the diameter of a human hair. Which shows how powerful and effective a pollen filter is. 

Dust and pollen filters: Benefits at a glance

What’s all the fuss about? Here are the cabin air filter benefits you will enjoy with a MANN-FILTER product:

  • Performance – Our premium products offer exceptional performance in cabin air filter technology
  • Wellbeing – Clean air improves the health and wellbeing of everyone traveling in the vehicle
  • Efficiency – Servicing and replacing the air conditioning filter in a car regularly improves system functionality
  • Support – Our easy to use online catalogue and simple installation instructions provide the guidance for a perfect fit!

What you need to know about changing a cabin air filter

Replace your cabin air filter after 15.000 km or every year

Cabin air filter replacement is vital to keeping the air clean inside your vehicle. This is often done as a feature of your regular servicing regime. Cabin air filters should be replaced once a year or every 15,000 km. To optimize the clean air inside the car and improve the driving experience, check your cabin air filter annually.

How will you know if your cabin air filter needs changing? 

  • Listen out for strange noises. These could be caused by deposits inside the filter
  • Watch for unpleasant smells
  • Poor air flow is a sign of a clogged cabin air filter
  • If your windows fog up frequently and are hard to clear, change your filter
