HYLA Worldwide

HYLAs are successfully sold worldwide in over 70 countries. The company started in 1990 and has its international sales headquarters located in Stuttgart, Germany.


Hartmut & Filiz Gassmann are the original Importers of the HYLA Air & Room Cleaning System in the United States since 1996. Beginning in a small office located in Greenville, SC, they operated from a single 1,900 sq ft office, building a nationwide, full-operating company.

Within only two years, the business had experienced such growth that they relocated to a larger office in South Florida. Utilizing their expertise in the industry, and with the intentions of optimizing workflow, Mr. & Mrs. Gassmann designed and built the new and final home for the HYLA USA Corporate Headquarters. Relocating to it in 2004, the Headquarters is a prestigious 11,000 sq ft building located in Deerfield Beach, FL.

It not only serves the basic functions of distribution, marketing, administration and customer service, but also provides the HYLA USA network with a home away from home. Mr. & Mrs. Gassmann have since successfully grown their business to include more than 90 offices and 450 associates nationwide, winning their first HYLA International Award in 2001 as Top Importer Worldwide.

Both not only oversee all U.S. Headquarters operations, but also – and most importantly – support their Distributors, Supervisors, and Staff nationwide. Mr. & Mrs. Gassmann have been the sole owners of the HYLA USA Corporate Headquarters since its construction.
