The Royi N99 Replaceable Silicone Face Mask protects you from all PM 2.5—not just COVID-19. With an FDA-approved design, this N99 mask is also reusable. So you can simply wash the main mask body and then use it over and over again. That means this silicone face mask is more eco-friendly than others as you won’t toss it to use an entirely new mask. What’s more, the filter inside the mask is replaceable when it’s worn out. Lab-tested and certified to have N99-level mask protection, this fully sealed mask ensures nothing nasty gets in anywhere. Additionally, it’s totally nontoxic, antibacterial, and odorless so you can ensure it won’t bother your skin. Because it seals so well against your face, this mask won’t fog up your glasses, either. Finally, choose from several colors: Black, White, Grey, Blue, and Pink.
