'Better-quality masks can be expensive - perhaps $5 for a single N95 mask,' Gottlieb wrote. The next best option are surgical masks, which could offer protection of about 60 percent, Gottlieb said. A standard face mask creates a barrier between the nose and mouth and any droplets or germs in the environment. Gottlieb said masks that are typically sold on websites such as Amazon are for allergies, not surgical masks. He recommends people check if their masks are true surgical masks to see if they've been cleared by the FDA and offer levels of protection, up to level three.
