What is the primary advantage of using dust masks?

The primary advantage of using dust masks lies in their low cost. Dust masks are typically designed for single-use or short-term applications and are often made from inexpensive materials that enable easy accessibility for a wide range of users. This affordability makes them a practical option for various settings, from construction sites to home improvement projects, where individuals may need protection from inhaling dust and particulates.

While other options suggest benefits like durability, reusability, or effectiveness against all particles, these characteristics are not primary advantages of dust masks. Many dust masks are not built for long-term use and may not offer the same level of protection as more advanced respiratory equipment. Additionally, dust masks are typically effective against nuisance dust and larger particles but may not provide adequate protection against smaller, harmful particles or chemical vapors, highlighting the importance of choosing the right respiratory protection based on specific work environments and conditions.
