How Particulate Respirators Protect You from Airborne Hazards?

Particulate respirators protect individuals from airborne hazards by filtering out harmful particles before they are inhaled. These hazards may include dust, smoke, and other airborne pollutants that can cause respiratory problems, such as asthma and lung disease.


Particulate respirators work by using a filter made of different materials, such as activated carbon and electrostatically charged fibers, to capture harmful particles. The filter’s effectiveness depends on its filtration efficiency, which is measured by the percentage of particles that the filter can capture. The NIOSH provides ratings for respirators based on their filtration efficiency, which ranges from 95% to 99.97%.


It is important to note that particulate respirators are not effective against gases, vapors, and other airborne contaminants. Respirators designed for these hazards require different filtration systems, such as activated carbon or chemical cartridges. Understanding the type of hazard present in the work environment is essential for choosing the appropriate respirator for maximum protection.


A combination gas/vapor and particulate filter is a popular choice for users who work in areas containing both gases and vapors. These types of respirators are available from most manufacturers and are sold in 2-packs. This type of filter is typically used in situations involving spray painting, pesticides and other applications where both gases and vapors are present.
