ContaminExpo 2027 in Paris: where to stay near Porte de Versailles

ContaminExpo is the benchmark trade show in France for contamination control and cleanroom environments. Held every two years, it brings together manufacturers, end users, suppliers, experts and researchers who design, run and evolve controlled environments. The 2027 edition marks its 20th anniversary and takes place in Hall 5.1 at Paris Expo Porte de Versailles. The event pairs an exhibition floor —featuring products, processes and equipment for handling particulate, chemical and biological contaminants— with the ContaminExpert scientific congress, which requires a separate paid registration and focuses on technical, regulatory and field-experience content. Located in southwestern Paris next to the Porte de Versailles station (metro line 12, trams T2 and T3, buses 39 and 80), the venue is easy to reach from across the city. Out-of-town attendees often stay at hotels around Issy-les-Moulineaux and the 15th arrondissement, just minutes from Hall 5.1. Entry to the exhibition area is free with prior registration; the congress requires a dedicated ticket. Sessions cover regulations, new technologies and applied case studies on contamination control.
