Curran Biotech has developed the breathable and environmentally friendly coating that can be put on filters to stop COVID-19 spreading. It calls Capture Coating. The coating can be applied to any filter – old or new – so no potentially expensive equipment needs to be installed. In addition, it is made of eco-friendly materials. The coating only needs to be applied once and it will last the lifetime of the filter.
