Ceramic fiber products can affect indoor air quality and human health in various ways. These products, when used in construction or insulation, can release fine particles into the air. Prolonged exposure to these airborne fibers may lead to respiratory issues and other health problems. However, modern ceramic fiber products are often treated to reduce the release of fibers, and their health risks are generally considered low when used and handled properly. It's important to follow safety guidelines and use personal protective equipment when working with these materials to minimize exposure and ensure a healthy indoor environment.
