Abstract:
The present invention relates to a mask which has no straps, is wearable through insertion into the nose while surrounding the mouth, and has an easily replaceable filter, wherein: a wearer can wear the mask by inserting insertion parts of a nose mask into the wearer's nasal cavity and surrounding the inner and outer parts of the wearer's lips by a lip fixing part of a mouth mask, so that the mask can be easily worn and can securely filter external pollution sources; the mask is wearable without straps, so that the mask is comfortable even when worn for a long time and a filter thereof can be easily replaced; a wearer can wear the mask by surrounding the inner and outer parts of the lips with the lip fixing part, which is separated into upper and lower parts or integrally formed in the mouth mask, so that the wearer does not feel a foreign body sensation; and a wearer can easily speak because of elastic wrinkles formed on a cover of the mouth mask.
