Under its founders, Glasfloss expanded its’ plants into Dallas, Texas (1956), and Millersport, Ohio (1964) Crooksville, Ohio (1973) and Juneau, Wisconsin (1978). To meet increasing demand for higher efficiency filtration, in 1988 Glasfloss acquired Air Lab, Inc., a manufacturer of HEPA and other high-efficiency grade filter products. These fine products are now produced at the Ohio and Dallas plants. Our Founder, Horace Lange died in 1993. Doris Lange, his daughter served as corporate president for several years until her death in 1994. Since the early 1990’s it has been the third generation family members and a solid group of key managers who have driven the business, continuing the mission to serve customers, employees, and partners. In 1999, Glasfloss consolidated its Ohio operations in Lancaster, Ohio, to improve production efficiencies and lead times. Additionally in 1999, Reno, NV plant was opened to serve the West Coast and in 2002 Jacksonville, FL was opened to serve the Southeast. In 2016, the Dallas, Texas plant and corporate office headquarters relocated to a larger facility in Desoto, Texas which gives Glasfloss additional manufacturing, warehouse and dock space to better serve our growing markets.
