Data centers require highly controlled air quality to protect critical Information Technology (IT) infrastructure from airborne contaminants such as particulate, volatile organic compounds (VOCs), and corrosive gases. Uncontrolled contamination can lead to overheating, hardware failure, and reduced operational efficiency.

This best practice guideline establishes air filtration standards for the removal of particulate and molecular contaminants in computer data centers. It provides facility managers with one of the necessary tools to maintain air cleanliness and protect critical IT infrastructure from airborne contaminants, ensuring the highest standards of air purity while maintaining energy efficiency and cost-effectiveness.
