What is a cabin air filter?
- A filter for a house in the middle of the woods?
- A fresh, piney scent?
- A filter for the passenger compartment of your car?
Clever you, it's 3.
A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors.
These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.
Now not all vehicles in the Los Altos area have cabin filters. They are fairly new on the scene in CA. About forty percent of new vehicles come with cabin air filters, but the number is growing every year.
Cabin air filters can make for a very nice driving environment for Los Altos car owners. Your car can be a haven during CA allergy season with very little dust and pollen getting into the cabin. However, like all filters, your cabin air filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your owner's manual for recommended replacement intervals. Often, the owner's manual forgets about the cabin air filter, so ask your service technician for a recommendation. It's usually every year or 12,000 miles/ 19,000 kilometers. Change it sooner if you drive in dusty conditions or if you start to notice an odor from your ventilation system.
So keep your cabin air filter clean. It may not help with your brother-in-law in the backseat, but it will make your driving experience more enjoyable.
