The Department of State is seeking information regarding the availability of air purification equipment for overseas use, specifically through a Request for Information (RFI) issued by the European Logistics Support Office (ELSO) in Antwerp, Belgium. The procurement aims to identify commercial air cleaners and filters that meet stringent technical specifications, including a Clean Air Delivery Rate (CADR) of at least 240 CFM, True HEPA filtration, low noise levels, and ENERGY STAR® certification, suitable for various indoor spaces. This initiative is critical for ensuring safe and effective indoor air quality in U.S. facilities across Europe. Interested parties should direct their responses to primary contact Mikel Alderman at aldermanml@state.gov or secondary contact Kristel De Maeyer at demaeyerk@state.gov, noting that this RFI is for information purposes only and does not constitute a contract award.
