How do filters help filter the air?

air conditioner filter

Filters are located just above the evaporator coils, where they help to remove particles from the air stream in order to keep the air and the air conditioning system clean. Because filters absorb particles from the air, eventually they will get saturated with particle, leading to a reduced air flow through the system. When this happens, the performance of the system declines and can even become a source of air pollution. As a result, it is recommended that a new filter is put in periodically in order to upkeep the efficiency of the system.
