==== Introduction ====

A respirator is a device designed to protect the wearer from inhaling hazardous atmospheres, including fumes, vapours, gases and particulate matter such as dusts and airborne microorganisms. There are two main categories: the air-purifying respirator, in which respirable air is obtained by filtering a contaminated atmosphere, and the air-supplied respirator, in which an alternate supply of breathable air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contaminants.

Air-purifying respirators range from relatively inexpensive single-use, disposable face masks sometimes referred to as a dust mask to more robust reusable models with replaceable cartridges often called a gas mask.

==== Challenges ====

Adequate testing and certification are desirable, especially for DIY health equipment.

==== Approaches ====

Locally produced medical supplies can supplement mass produced supplies, or provide a remedy where none exists at all.  Several useful objects are provided in that spirit.
