The copper oxide particles are potent for life and their ability to repel viruses do not decline significantly over time. However each country has it’s own regulations with regard to the use of medical devices, this mask included, especially in times of a global pandemic. Some countries recommend to re-use masks and some do not. Please make sure that you are using the mask in compliance with your country / region policy. For clarity sake the Copper Inside mask is categorized as “disposable” – please consult your local public health officials in case of doubt.
Please note: disposable products are products that can be thrown away after it becomes unused (e.g., physical damaged). Physical damage affects the mask efficiency.
In case of physical damage please dispose the mask and replace with a new one.
