Electronic hardware is sensitive to airborne contaminants. The computer room should achieve a high level of cleanliness and minimize airborne dusts, gases, and vapors that can impact performance and reliability of the hardware. Failure to maintain the computer room according to the standard may result in interference or actual component failures.

For details of the clean room standard, refer to:
  • ASHRAE HVAC Applications: Chapter 16, Clean Spaces. American Society of Heating, Refrigerating and Air Conditioning Engineers, Inc. 2003, 2011 Gaseous and Particulate Contamination Guidelines for Data Centers.
    1. Go to https://www.ashrae.org/.
    2. Search for contamination.
    3. Open the 2011 Gaseous and Particulate Contamination Guidelines for Data Centers PDF file.
For particulate (dust) contamination, ASHRAE recommends that data centers be kept clean to ISO 14644-1 Class 8, which may be achieved simply by specifying the following means of filtration:
  • The room air may be continuously filtered with MERV 8 filters, as recommended by ASHRAE Standard 127 (ASHRAE 2007).
  • Air entering a data center may be filtered with MERV 11 or MERV 13 filters as recommended by ASHRAE (2009b).
For gaseous contamination, ASHRAE recommends that data center operators maintain an environment with corrosion rates within the following guideline per ISA-71.04 (ISA 1985):
  • Copper reactivity rate of less than 300 Å/month
Further, due to limitations from copper reactivity, ASHRAE recommends the addition of the following guideline in addition to the above copper reactivity rate:
  • Silver reactivity rate of less than 200 Å/month
