We suffered a long winter, but the weather is finally turning nice again. The sun it out, and it is hot! Wait… what is that smell?
The insides of our vehicles are subject to the same elements as the outsides. Especially here, in our Pacific Northwest Climate, your air ducts are going to collect moisture, mold and spores. Too much build up causes that musty smell coming from your air vents and turns your car or truck into an allergen on wheels! So how can we combat that?
Excess build up is a sure sign of poor filtration. You should always make sure that your air filters are clean and dry. Air filters don’t wick moisture, so heavy rainstorms can compromise their filtering abilities. If your air filter becomes wet – either from moisture in the air, or an exposed air intake system – replace it. A wet air filter is an ineffective air filter.
You should also make sure that you replace your air filter at the recommended intervals. Your engine air filter should be changed every 30,000 to 45,000 miles (or more often, if you drive many dirt or gravel roads). Your cabin air filter should be changed with every third oil change.
If you’re smelling something musty coming from your air vents, that means you’re breathing in whatever your filters have caught. To protect your vehicle – and your family – change your air filters regularly.
