Let’s talk about cabin air filters. There seems to be some confusion about them that we should be able to clear up. Much of the confusion starts because cabin air filters are relatively new to the Auto Repair Industry. Not all vehicles have them, so some people confuse their cabin air filter with the engine air filter.
Every vehicle has an engine air filter that cleans the air going into the engine, but not all have a cabin air filter that cleans the air going into the passenger compartment.
Easy to get mixed up.
The cabin air filter cleans out dust, pollen, spores and other pollutants. To give a point of comparison, a grain of sand is about 200 microns across. A cabin air filter can stop particles that are just 3 microns in size.
It really does make the passenger cabin a much more pleasant environment.
When the cabin air filter gets dirty, you just need to replace it. Your owner’s manual may have a recommended interval for changing it. If not, we can inspect it. You know, it’s ironic that many people who don’t realize they even have a cabin air filter first find out they do when it starts to get musty odor.
Some cabin air filters are very easy to access when it’s time to replace them. Other filters are not so easy and require some disassembly to get behind the dashboard to gain access. Care must also be taken to not allow dirt to fall down in the heater box and fan area. Vacuuming is commonly used in cabin filter replacement and clean up.
A clean cabin air filter keeps out smog, allergens and other harmful pollutants. J’s Auto Services Technicians monitor the condition of your filter at your service visits and recommend when it is time to change it.
