Selecting the right mask depends on the intended environment. For medical and healthcare settings, prioritize Surgical Masks (Type I, II, or IIR) or Medical Respirators (N95/FFP2). For industrial or construction use, focus on FFP3 or N99 respirators that filter particulates and dust. For general retail or promotional use, 3-ply civil-grade masks or reusable fabric masks are more cost-effective. Always verify the Bacterial Filtration Efficiency (BFE) and Particle Filtration Efficiency (PFE), which should ideally be ≥95% or ≥98% for professional grades.
