Putting on a respirator correctly is more than slipping it over your face - the donning order, strap tension, and seal check decide whether it protects you. This guide covers donning and doffing for half and full-face respirators, the bottom-up strap tensioning that creates an even seal, and the contamination-safe removal order.

Choosing a half mask respirator means matching the mask to your hazard, your face, and the cartridges you need - not just grabbing a popular model. This guide covers the assigned protection factor, elastomeric vs disposable, sizing, cartridge compatibility, the mandatory fit test, and the major brand series side by side.
