What is the role of air filters in the Cabin Atmosphere Control System?

The role of air filters in the Cabin Atmosphere Control System is primarily to purify incoming air from contaminants. This function is vital in maintaining a safe and comfortable cabin environment for passengers and crew. The filters trap particles such as dust, pollen, bacteria, and other pollutants, ensuring that the air circulated within the cabin is clean and helps prevent health issues related to air quality. By effectively removing these contaminants, the air filters contribute significantly to the overall well-being of everyone on board by providing fresh air that is essential for a healthy indoor atmosphere. This is especially important in sealed environments like aircraft, where outside air can carry various pollutants.
