According to information provided by the Warsaw University of Life Sciences, half of the reusable antiviral mask is made of algae placed in a thin layer of transparent material. When humans wear a mask, photosynthesis takes place. When the user breathes, the algae are supplied with sufficient moisture and carbon dioxide. The algae, in turn, provide oxygen for humans to breathe.

A series of experiments was performed to verify the invention. Scientists argue that the mask effectively absorbs viruses that cause upper respiratory infections such as Corona virus.

According to SGGW, the mask absorbs the virus based on the difference in electrical charge (viruses have a negative charge and algae have a positive charge). Then, as noted, the capsules or envelopes of the viral proteins break down and the now harmless interior disintegrates.
