What Are the Symptoms of a Clogged Cabin Air Filter in a Toyota Camry?

The cabin air filter keeps the interior air clean by filtering dust and pollutants. If clogged, you may notice:

Weak airflow from the A/C vents, even at full fan speed.
Unpleasant odors, especially a musty smell.
Increased dust inside the car, affecting passengers with allergies.
Foggy windows, as proper airflow is reduced.
Replacing the cabin air filter every 15,000–20,000 km ensures clean air circulation and better A/C performance.

A clogged cabin air filter can hinder the performance of the A/C system and reduce air quality in the cabin. Common signs include:

Weak airflow from the A/C vents, even when the fan is on full speed.
Unpleasant odors, often a musty smell due to trapped moisture and bacteria.
Increased dust inside the car, which may be problematic for allergy sufferers.
Foggy windows, as reduced airflow causes condensation.

To maintain clean air circulation and A/C efficiency, replace the cabin air filter every 15,000–20,000 km.
