KEY WORDS:respirator with valvefilter cartridgecombined vapor cartridge
It purifies inhaled air by filtering and adsorbing harmful gases, vapors and particulate matter in the air with cartridges / filter cotton, protecting the respiratory tract from toxic and hazardous substances. Its protection falls into two main categories:

1. Particulate Protection (Filter Cotton)
Blocks tiny solid particles:
Dust: dust generated from grinding, mining, cement processing and woodworking
Aerosols: haze, fumes, welding smoke, droplets, pathogen-laden aerosols
Solid particles such as rust, glass fiber and coal dust

2. Protection against Toxic Gases / Vapors (Gas Canisters / Cartridges)
It repels various harmful gaseous pollutants via activated carbon adsorption and chemical neutralization:
Organic vapors: paint thinners, formaldehyde, benzene, toluene, xylene, adhesive solvents, gasoline, ink volatile fumes
Acidic gases: hydrochloric acid, sulfuric acid mist, sulfur dioxide, hydrogen sulfide, chlorine
Alkaline gas: ammonia gas
Capable of partially protecting against volatile industrial substances including cyanides, formaldehyde, ketones and esters
