About the company
Bost & Filtrex, Inc., doing business as Ketchum & Walton CO., supplies HEPA filters, air handler units, and air filtration systems to federal agencies as a prime contractor (96% of recent awards) competing without set-aside designation. The company is a for-profit Subchapter S corporation and subsidiary of Ketchum & Walton Co., headquartered in Columbus, Ohio, with performance operations in Grandview, Ohio.
Bost & Filtrex's capability portfolio centers on air filtration products and systems for federal facilities. Representative work includes a $249,030 firm fixed-price purchase order from the Smithsonian Institution (May 2024) to design, fabricate, and install a fan filtration system with completion in September 2024; a $33,582 purchase order from the Smithsonian for HEPA filters at the Hirshhorn Museum (April 2025, completed May 2025); and a $18,319 purchase order from the Smithsonian for USRO supplies at the National Museum of Natural History (July 2026). The company also supplies specialized filters—including 23-3/8" x 23-3/8" x 12" Camfil XH ABS HI 99.97% filters—to the Department of Health and Human Services National Institutes of Health and air filtration products to the Department of the Navy. The vendor's award classifications reflect this product mix: top NAICS categories include Plumbing, Heating, and Air-Conditioning Contractors (12 awards) and Hardware Manufacturing (2 awards); top PSC codes are Refrigeration and Air Conditioning Components (4 awards) and Filters and Networks (3 awards).
Customer concentration is extreme and tilted toward a single agency. The Smithsonian Institution accounts for 17 of 22 tracked awards (92% by count) and $551 thousand of $728 thousand combined potential value (76% by dollars). The Department of State Bureau of Near Eastern Affairs, the Department of Health and Human Services National Institutes of Health, and the Department of the Navy round out the customer base but collectively account for less than $160 thousand. Activity has been volatile—five awards in 2021, three in 2022, five in 2024, and one each in 2025 and 2026—with combined dollars obligated ($775 thousand) exceeding combined potential value by 6 percent, signaling recent work completion. Bost & Filtrex maintains one subcontract relationship: a February 2024 sub-award to Huang's Inc. for soundproof door systems installation on the LBJ Training Development Center renovation project. The vendor does not sit on named parent vehicles beyond a single IDC (47PM0518D0023 with one task order).
