Where is the cabin air filter located in a Mazda 5?

[WilliamDella]

The cabin air filter in a Mazda 5 is located under the dashboard in front of the front passenger seat, near the evaporator unit. Additional relevant information is as follows: 1. The primary function of the cabin air filter is to filter dust from the air, preventing dust from entering the evaporator and forming sludge that could clog it. If the airflow from the vents noticeably decreases, this indicates a clog. 2. Over time, the car's cabin air filter accumulates various impurities and dirt, making cleaning essential. For a dirty cabin air filter, remove it from the vehicle for cleaning. Generally, it is recommended not to wash it with water. Instead, use a high-pressure air gun to blow away dust and debris from the filter. As for the foam layer, it can be cleaned with laundry detergent, dried thoroughly, then lightly coated with engine oil by hand, ensuring even distribution. Use tissue paper to absorb any excess oil before reinstalling it.
