What we need:

A technology that works continuously in the air to keep us healthier.

Dangerous pathogens are in our indoor air everywhere.

COVID showed us: this is a major issue.

The impact is enormous: too much illness, too much money every year.

A Breakthrough Innovation in Indoor Air Treatment

Grignard Pure, LLC is a 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 EPA registration for mold and mildew odor elimination and prevention, and for its unique air treatment solution which, pending EPA registration, will be effective and safe for use in all indoor occupied spaces for the elimination of airborne pathogens.
