Always refer to the vehicle's manual, but as a general guide the cabin air filter should be replaced once a year or every 15000 to 25000 miles. Pollen filters normally cost between £10 to £30 depending on brand and fit for vehicle model.

While replacing a pollen filter is simple and quick, access can be difficult. Refer to the vehicle's manual for guidance and to avoid snapping off any retaining clips.

This example shows how to find the filter in a Honda Civic. The glovebox is prevented from opening out completely by plastic pins on either side. Push them gently inward to disengage. Once the glovebox is fully open the cabin air filter can be found behind a plastic faceplate. Remove it by pressing the clips on both sides simultaneously. Slide out and replace the filter with a new one, noting air flow direction. Reattach the faceplate and close the glovebox.
