4 Signs Your Cabin Air Filter is Dirty

Driving a vehicle with a dirty cabin air filter is not only unhealthy for your long-term well-being, but it also brings a variety of negative effects to your driving experience.

Continue reading to learn more about changing your cabin filter and why it’s important.

4 Signs Your Cabin Air Filter Should Be Replaced

A dirty cabin air filter doesn’t go unnoticed unless you grow accustomed to the musty smell and reduced airflow coming from the vents. Although you may not notice it right away, passengers can definitely smell it. It’s a more pleasant and healthy driving experience when you have a clean cabin air filter, so here are a few of the signs to look out for of a dirty one:

1. Musty Smelling Cabin

The most obvious sign of a bad cabin air filter is the smell that comes from the air vents, especially right when you start the blower motor. From animals nesting to moisture and dust, cabin air filters catch many contaminants that you don’t want to breathe in every day.

2. Reduced Air Vent Flow

Turn on your A/C or heat, then you should immediately know if the cabin air filter is due for a change, as it will not only smell musty, but you will notice a significant reduction in air flow from the vents. Changing the filter will restore proper air flow, making your cabin cool down and heat up as intended.

3. Filter Hasn’t Been Changed in a Year

If you can’t remember the last time you changed the cabin air filter of your vehicle, it’s likely due for a change, especially if it’s positioned in a hard-to-reach place. Neglecting to change your cabin air filter can make your A/C and heat work harder than needed, adding more stress to those systems.

4. Increased Interior Dust

A clear sign of a bad cabin air filter is when dust starts to accumulate in the cabin of your vehicle at a much higher rate than before. It’s a good idea to inspect your cabin air filter and change it regularly to keep your cabin air fresh and healthy.

    A cabin filter should be changed every year or 20,000 kilometres. However, if you find yourself driving over dirt roads often, you should check and change your filter more often.
