When to change your pollen filter
“Poor air flow from the vents can be caused by a clogged filter”
When to change a pollen filter? Car manufacturers tend to recommended that cabin filters are renewed every 19,000-24,000 km or around once a year. If you don’t know when yours was last changed there are a couple of things to look for that tell you it’s time to renew it. First, air flow from the vents may be poor. This reduces over time, so it’s difficult to spot but it’s caused by a clogged filter.
Another sign that it may be time to change your pollen filter is a musty smell in the cabin. This can also be caused by a build-up of bacteria in the air-con system, and can be cured by turning the fan speed and temperature up to max for 10 minutes or so, but it’s a sign that the pollen filter needs to be replaced.
All cars are slightly different, so if it is time to change your pollen filter, find your car for specific instructions.
