Indoor air quality plays a crucial role in maintaining our health and well-being. With the ongoing COVID-19 pandemic, the demand for masks that can effectively filter airborne particles has soared. One option that has gained popularity is the FDA-approved black KN95 mask. In this article, we will explore whether these masks can indeed improve indoor air quality by examining various aspects.
1. Filtration Efficiency
FDA-approved black KN95 masks are designed to filter out at least 95% of airborne particles, including bacteria, viruses, and pollutants.
