The types of respirators can be classified according to their shape, place of use and composition.
Respiratory masks can be divided according to their shape: flat respirators, cup respirators, valve respirators, and foldable respirators. This type of mask is mainly used in low-density and low-toxic places with normal air pressure and air circulation.
Mask-type respirators, half-mask respirators, single-can respirators, double-can respirators, isolation gas respirators. Such respirators are mainly used in environments with high density and high toxicity!
Among them, the isolation type respirators can be used in some special places, such as airtight and highly toxic spaces, but the price is relatively high and it is not very convenient to use!
