Leadoff Studio worked closely with CastleGrade to develop an eco-friendly package to store, protect and extend the life of their reusable face masks. The CastleGrade G Series mask is one of the most effective face masks widely available, testing at a 98% filtration efficiency level for airborne particles. The company’s mission is to cut down on the waste created by disposable face masks from the COVID-19 pandemic.
CastleGrade’s customer base primarily consists of medical professionals, teachers and other essential workers. They loved the usefulness of the mask but found that it would get unsanitary too easily between uses or during transport.
