When both particulates and gases/vapors toxic by inhalation are anticipated to be in your breathing zone during handling, the pesticide label will specify respirators with both a chemical purifying element and a particulate filter. Combo cartridges for non-powered air-purifying respirators can have either N, R, or P rated filters. Combination chemical cartridges for powered air-purifying […]

Particulate Filter Use Limitations
For pesticides, EPA regulations [40 CFR 170.507(d)] require the replacement of particulate filters when damaged, torn, soiled, or it becomes uncomfortable for the wearer to breathe. Additionally, particulate filters should be replaced according to respirator manufacturer recommendations or pesticide labeling (whichever is more frequent). For example, filtering facepiece respirators (FFRs) are designed by respirator manufacturers […]
Particulate Filters
Particulate filters remove aerosols suspended in the air that you breathe (e.g., dust, mist, fog, smoke). Particulate filters DO NOT remove gases or vapors. The pesticide label specifies N, R, and/or P filters for non-powered air-purifying respirators (APRs), and HE for powered air-purifying respirators (PAPRs). Particulate filters for non-powered air-purifying respirators are rated for both oil […]
