A new nanocoating from Curran Biotech, based in Houston, Texas, professes to effectively and cheaply stop the spread and lingering impacts of the SARS-CoV-2 virus when applied to the filter fabrics in common HVAC (heating, ventilation and air conditioning) systems.
Curran’s Capture Coating permanently bonds to the porous materials within a filter, stopping viruses, bacteria and fungi dead, while not impacting airflow or breathability.
Standard air filters are rated using the MERV (Minimum Efficiency Reporting Value) system – with MERV8 typical for public buildings. With the Curran Biotech Capture Coating, these filters outperform much higher rated filters in terms of viral protection, without impacting airflow (static air pressure).
Curran Biotech treated filters operate normally with regard to dust and other dry particulates but reject aqueous/liquid-phase contaminants. Because the coronavirus in its most infectious state is surrounded by an aqueous liquid-phase environment, Capture Coating physically stops the virus at the surface of the air filter.
Capture Coating is being made available now from distributors and retailers across the globe. It is already being used in 11 states across the United States and it is to be expanded to 25 with the next few weeks.
