What are the three levels of oil degradation resistance for Non powered APR particulate filters?

1. N series, R series, P series

2. A series, B series, C series

3. X series, Y series, Z series

4. M series, N series, Q series

The correct answer is: N series, R series, P series

The three levels of oil degradation resistance for non-powered air-purifying respirator (APR) particulate filters are classified into the N series, R series, and P series. This classification system is designed to help users select the appropriate filter based on their specific work environment and the presence of oils. - The N series filters are not resistant to oil, making them suitable for environments where oil aerosols are not present. - The R series filters can resist some oil aerosols for a limited time but are not intended for use in heavily oil-contaminated environments. - The P series filters offer a high level of oil degradation resistance and can be used in environments where oil aerosols are present continuously. This structured classification allows individuals to understand the suitability of the filters based on the anticipated exposure to oil, thereby enhancing safety and protection in various occupational settings.
