Our Story
Bleu Garde™, LLC envisions a 21st-century world fortified against infectious diseases, where prevention, containment, and cure are not just ideals but realities accessible to all.
The company was borne in the midst of the most devastating global pandemic in a century, with the belief on the part of its founder, Etienne Grignard, that an existing technology he knew well - in the fog and haze fluids he had developed twenty years earlier as a safe effective medium for extended exposure to the theatrical haze and fog that enhances lighting effects on Broadway and other live stages- could be effectively modified for use as an antimicrobial solution in the battle against SARS-CoV-2. This innovative breakthrough became the first-of-its-kind air treatment approved by EPA under an emergency exemption to mitigate the spread of COVID-19.
Today, we are committed to leading the charge in global health innovation. Our goal is to revolutionize disease mitigation, ensuring equitable access to health services and fostering a world where every community, regardless of economic or social status, is empowered to stop outbreaks before they start and safeguard the health of its people. In this vision, we see a future where the burden of infectious diseases is significantly reduced, and global health security is a shared, attainable right.
Meet the...

Bleu Garde™, LLC is an emerging leader in developing next-generation indoor air treatment solutions for disease mitigation, indoor air quality, and pandemic response. In 2021, the EPA awarded the Company the Agency’s first-ever emergency exemption for an airborne antiviral effective at eliminating the SARS-CoV-2 virus in the air.
The Company’s proprietary, patented technology is the foundation for its first EPA registration, for mold odor elimination and prevention, and for its unique air treatment solution which, pending final EPA registration, will be effective and safe for use in all indoor occupied spaces for the elimination of airborne pathogens.
