Recently, the air quality is deteriorated due to fine dust or yellow dust, and the number of people wearing the mask 400 is increasing to protect health due to the emergence of a new virus. And, in order to more effectively block the fine particles in the air, the demand for a mask with a high dust blocking rate (for example, KR, N, KN) is increasing day by day, but as the dust blocking rate increases, the exhaust resistance of exhalation is also increased. tends to

The filter unit 410 constituting the mask 400 of the present invention may be composed of a MB (melt blown) filter or a combination of a nano filter and an additional nonwoven filter or a functional filter, and forms about 1 to 5 layers. and can be configured.

When the exhaled breath is not smoothly discharged during exhalation, and the exhausted exhalation is re-inhaled while remaining inside the mask, there is a problem in that the air containing carbon dioxide or odor remaining in the exhalation is re-inhaled by the inhalation.

In addition, glasses users experience difficulties in securing vision as a part of the exhalation exhaust is leaked through the gap between the mask and the skin, and moisture contained in the leaked exhalation is condensed on the spectacle lens due to the temperature difference between the outside air and the exhalation. In order to solve this problem, a mask equipped with an exhaust valve without a filter is also introduced so that the exhaled breath is discharged without exhaust resistance, but in the case of a patient infected with an infectious disease, it is undesirable for public health because viruses or bacteria may be present in the exhaled breath, and in some countries or Local laws prohibit the use of masks equipped with these exhaust valves.

According to the breathing guide device 100 and the mask system having the same according to the present invention, the mask 400 wearer exhales with the breathing guide device 100 mounted inside the filter unit 410 of the mask 400 for air purification. It can be configured to be exhausted so that exhalation and inhalation do not mix.
