Driving without a cabin air filter is not recommended, even if it does not have a direct impact on engine performance. While there are no health risks associated with this, it can lead to small leaves and debris getting stuck in the system. This is because the filter is responsible for trapping harmful particles from the air entering your car, such as dust, engine fumes, dirt, twigs, leaves and debris. The filter efficiency of all cabin air filters for particles with sizes of 520 nm is between 35 to 60%.A new cabin air filter will prevent pollen from entering the vehicle and causing its occupants to start sneezing or worse.
It also ensures that passengers don't have to roll down windows in the middle of winter to get fresh air. Electrostatic filters provide 20-60% better filter efficiency than other cabin air filters at all particle diameters (6 — 520 nm).When air passes over the cabin air filter, debris is trapped by the filter and stops instead of being pumped into the car. Dirty or excessively clogged cabin air filters can produce a dusty and damp odor, especially when the HVAC system is turned on. If the filter is clogged, airflow is restricted and the filter can start emitting bad odors. It is important to replace your cabin air filter at regular intervals to ensure that it is working properly.
Be careful not to break any of the clips or pins that hold it when accessing it. Just because a cabin air filter doesn't directly affect your vehicle moving from point A to point B doesn't mean you should delay buying a new one or not replacing it at all.
