The present invention relates to a nose mounting body (100) for purifying air. The nose mounting body (100) comprises: a nose hole insertion tension body (10) formed to have an outer diameter (11) and an inner diameter (12), having multiple rectangular or circular tension pillars (14) in the top of the top surface (13) of a cylinder having a top and a bottom which are opened, and having a circular or ellipse-shaped nose hole pressing body (15) formed in the top of each of the tension pillars (14) a nose hole sealing tension body (20) formed to have an outer diameter (21) and an inner diameter (22), and having a hat-shaped sealing tension body (23) formed in the top of the top surface of a cylinder having a top and a bottom which are opened to be larger than the outer diameter (21) at approximately 15 degrees on the basis of a horizontal state a bottom holder (30) formed to have an outer diameter (31) and an inner diameter (32), having a fitting stopping circular stopper (33) in the bottom of a cylinder having a top and a bottom which are opened to be larger than the outer diameter (31), and having a withdrawing band (34) vertically formed on the rear bottom surface of the circular stopper (33) and a disc-shaped air purifying filter (40). The outer diameter (11) of the cylinder of the nose hole insertion tension body (10) is fitted to the inner diameter (22) of the cylinder of the nose hole sealing tension body (20). The outer diameter (31) of the bottom holder (30) is fitted to the bottom of the inner diameter (12) of the cylinder of the nose hole insertion tension body (10). The air purifying filter (40) is inserted in the top of the inner diameter (12) of the cylinder of the nose hole insertion tension body (10).COPYRIGHT KIPO 2017외경(11)과 내경(12)으로 형성되며 상 하부가 개방된 원통 상면(13)에 상방으로 사각 또는 원형의 텐션 기둥(14)이 다수 형성되며, 다수의 텐션 기둥(14) 상부에 원형 또는 타원 형상의 콧구멍 누름체(15)가 형성되는 콧구멍 삽입 텐션체(10)와,외경(21)과 내경(22)으로 형성되며 상 하부가 개방된 원통 상면에 상방으로 갓 형상의 밀폐 텐션체(23)가 수평을 기준으로 15도 내외로 외경(21)보다 크게 형성되
