Calistair

Founded in 2014, Calistair is a material science and chemical technology company specializing in innovative air purification and contaminant capture. Its core technology, the Calistair Technology, utilizes a proprietary non-thermal catalysis method integrated into modular reactors. These reactors combine honeycomb structures impregnated with advanced materials—such as zeolites and metal-organic frameworks (MOFs)—with UV-C activation. This process generates hydroxyl and superoxide radicals that effectively mineralize and destroy airborne biocontaminants, volatile organic compounds (VOCs), chemical pollutants, and viruses, including coronaviruses, without producing toxic by-products like ozone. The technology is designed for scalability and high-velocity airflow, allowing it to be retrofitted into ventilation systems or utilized in dedicated air purification units.

Calistair's solutions are engineered to improve safety standards in environments ranging from hospitals, laboratories, and cleanrooms to industrial buildings and public spaces. The company serves a global client base, including medical facilities requiring high particulate cleanliness standards and industrial sectors focused on emission reduction and gas purification. Since its inception, the company has received recognition for its contributions to public safety, notably during the COVID-19 pandemic, and continues to advance its material science research for applications in energy storage, defense, and pharmaceutical sectors. Headquartered in France, Calistair maintains integrated R&D and manufacturing capabilities to support the implementation of its air decontamination technology across diverse industrial and medical applications.
