Half mask respirators
A half mask respirator is the first level of air purifying respiratory protection. Once adjusted and equipped with a filtering cartridge, it provides efficient respiratory protection against toxic gases and vapors (non-irritating to eyes), dusts and solid and thin particles. This personal protective equipment offers an excellent quality/price ratio.

Half mask respirator assets
Half mask respirator applications
As a half mask respirator – single filter gas mask or dual filter gas mask – only covers the respiratory tracts, the eyes are not protected by the mask. Thus using this respirator type is not recommended in presence of irritating gas. They however can be used for many applications depending on the selected respiratory protective filter but only if the respirator cartridge does not exceed 300 grams.
Particle filter - P3
Gas mask filter against solid and liquid particles, radioactive and highly toxic particles, bacteria and virus (asbestos, ceramic fibers, lead, flu viruses such as bird flu or A/H1N1 flu, SRAS...)
Gas filter - A2, AX, B2, E2, K2
Gas mask filter against organic gases and vapors like solvents with a boiling point above 65°C, inorganic gases and vapors like chlorine, hydrogen sulfide and hydrogen cyanide, acid gases and vapors like sulfur dioxide or ammonia and organic derivatives.
Combined filter - ABEK1-P3
There are only a few combined filters available for half masks protective respirators as gas + particle filtering cartridges oftentimes weight more than 300 grams. The ones that would be compatible with a half mask will be less efficient like an ABEK1-P3 gas mask filter (air purifying level 1 versus a more efficient level 2). Only A2-P3 filter cartridge are level 2 classified and compatible (mainly for the phytosanitary sector).
Half mask escape respirator for emergency evacuation
Half mask escape respirators are specific gas masks especially designed for emergency situations. They are composed with a half mask respirator (or a mouthpiece), a nose clip and a specific respiratory protective filter (usually ABEK2 filter). Half mask escape respirators are efficient against organic, inorganic (except carbon monoxide) and acid substances as well as sulfur and ammonia compounds.
As it is an air purifying respiratory protective equipment, an escape mask cannot be used if the oxygen rate in ambient air is below 19.5% volume.
