The mask of the invention of this patent publication is configured such that the valve curtain 4 is sewn and fixed, covers the mouth, and a valve curtain is added to the nose and lip, and the valve curtain 4 hangs down and discharges air. It is a mechanism that oscillates when and when it sucks and does not close or open the air outlet.

Further details of the harmful effects of cedar pollinosis are as follows.
First, the size (particle size) of cedar pollen is as follows.
In general, “Sugi pollen is about 25 to 35 μm in size and scatters over long distances in the wind. It flies from a distance of 10 km or more, sometimes 300 km” (Wikipedia Free Encyclopedia). However, a study by Fumiko Sugawara et al. “Study on dwelling cedar pollen aerosols”, Architectural Institute of Japan Architectural Proceedings No. 515, 75-81, January 1991 It shows a certain double mountain shape, and a small peak of 5 μm or less appears in the room with few large particles. ” This is because cedar pollen particles associate or break down.
Secondly, cedar pollen and allergies are explained as follows.
According to the technique of the National Sagamihara Hospital Clinical Research Center, the causative agent that causes cedar pollinosis is the pollen wall outer layer that constitutes the outermost layer of pollen and the orbicle that is fine particles adhering to the surface. Two major allergen Cryj1 Cryj2 proteins present. (Akihiro Sugi pollen allergen Vol.200 No.5 2002.2.2 from the history of medicine).
Therefore, allergens are adhered even to the broken small particles of 5 μm or less described in the first.

Third, the trapping of the mask particles will be described as follows.
“Super Defense Virus Pollen Mask FSC / 98S 20 Sheets” (¥ 7,245) has been released by Fan Medical, and it was reported that the collection rate was 99.77% in an experiment using pseudo virus particles 76 mm (0.076 μm). In general, low-priced and general pollen countermeasure masks have a cedar pollen particle size of 25 to 35 μm and capture 99% or more of them.

Fourth, the particle trapping of the cigarette filter will be described as follows.
Although it is possible to capture fine particles, it is not practical if the ventilation resistance (pressure loss) is large. The particle supplement of a general cigarette filter (ACF filter, Nippon Filter Industry (head office: Shibuya-ku, Tokyo)) is designed to capture particles of 0.3 μm or more.

Moreover, the ratio of the components in the air and exhaled breath is as follows.
Atmosphere Exhalation Oxygen 20% 16%
Carbon dioxide 0.04% 4%
Nitrogen About 79% About 79% In addition to this, water vapor is contained, and the amount of water vapor greatly depends on the temperature.
