What is one of the roles of the air conditioning system regarding air quality?

The air conditioning system plays a crucial role in maintaining air quality by keeping the air free of dust and contaminants. This is achieved through the use of filters that capture particles such as dust, pollen, and other airborne impurities, which is vital for ensuring a healthy environment within an aircraft.

Having clean air is essential not only for comfort but also for the overall safety and efficiency of the crew and equipment on board. The air conditioning system actively circulates and cleans the air, preventing the buildup of harmful particles that could affect both the aircrew's health and the operation of sensitive instruments.

While effective humidity control and pollutant filtration are important aspects of air conditioning systems, the specific focus on keeping air free of dust and contaminants highlights the system's role in promoting a safe and comfortable atmosphere for personnel.
