The N95 surgical mask has long been considered the ‘gold standard’ for protection against Covid-19.
However, a study posted by the National Institutes of Health indicates that wearing these medical-grade masks could expose users to dangerous levels of toxic volatile organic compounds (TVOCs).
South Korean researchers from Jeonbuk National University examined various types of disposable medical-grade masks, including several reusable cotton masks. They discovered that the chemicals emitted by these masks exceeded the recommended safety levels for TVOCs by eightfold. Breathing in TVOCs can cause headaches and nausea, and long-term exposure has been associated with organ damage and even cancer.
