What is the purpose of an air conditioning filter?

[LawsonLynn]

The air conditioning filter serves to separate solid impurities such as dust, pollen, and abrasive particles from the air, as well as to adsorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., providing strong and long-lasting moisture absorption. The air conditioning filter is a type of filter installed in the car's air conditioning system, capable of absorbing particulate matter, reducing respiratory discomfort, minimizing irritation for allergy sufferers, and protecting the air conditioning cooling system. Location of the air conditioning filter: 1. Some air conditioning filters are located beneath the front windshield of the car, covered by a drainage trough. To replace the filter, first open the engine hood, remove the clips securing the drainage trough, detach the trough, and the air conditioning filter will be visible; 2. In most household sedans, the air conditioning filter is situated in the storage compartment under the front windshield on the passenger side, making it extremely convenient to access. Simply remove the storage compartment to reveal the air conditioning filter inside.
