The Department of Justice, specifically the Federal Bureau of Investigation (FBI), is seeking information from vendors regarding trace evidence filters to support its Evidence Response Team Unit (ERTU). The Request for Information (RFI) outlines the need for filter assemblies that are compatible with personal vacuum cleaners, emphasizing specifications such as dimensions, durability standards (IP54 dust and water resistance), and secure packaging to prevent contamination. These filters are crucial for the efficient collection of microscopic evidence in forensic investigations. Interested vendors are encouraged to submit their capabilities and innovative product suggestions by September 1, 2025, with inquiries accepted until August 25, 2025. For further details, vendors may contact Adelle Bolton at albolton@fbi.gov.
