Cabin Air Filter Maintenance

The cabin air filter is a simple component that does an important job when it comes to a pleasant driving experience. It scrubs the air of airborne particulates to ensure the freshest air enters the cabin where you and your passengers breathe. The limitation of the cabin air filter is just like all other filters, it is a paper composite that maximizes particulate collection to create a pleasant driving experience, but the paper composite design shortens its life relative to other components. Cabin air filters ultimately need replacement service to install a brand new filter.

How Often Should Cabin Air Filters Get Replacement?

Lexus generally recommends cabin air filter replacement every 10,000 miles. This interval makes it easy for Lexus owners with synthetic oil changes every 10,000 miles to also replace the cabin filter with oil changes. You should also know the cabin air filter trouble signs, especially if you drive in dirty environments, and replace the filter if it gets clogged prematurely.

Clogged Cabin Air Filter Trouble Signs

Clogged air filters cannot trap the airborne particulates properly. The particulates can bypass a clogged filter and enter the cabin. You should get the cabin air filter inspected and replaced if you notice any of the clogged cabin air filter trouble signs:

• - Unpleasant odors often described as dirty, moldy & musty
• - The filter paper is clogged with grime
• - Restricted airflow out the vents
• - Strange noise when the blower motor is turned on
