Then, when the fine dust from the outside is about to be introduced into the room, it can be blocked by the HEPA filter 136, so that indoor air pollution by the fine dust can be prevented.

Since the HEPA filter 136 serves to block fine dust, air without fine dust may be introduced into the room. Since the air permeability is low, the ventilation of the room may not be done well in the weather with little fine dust.

Therefore, in the case of a weather with little fine dust, the window 20 may be opened up to a position where all of the insect screens 120 are opened.

Then, the outdoor air does not flow into the entire open area A2 of the insect screen 120 , but a portion may be introduced through the HEPA filter 136 , and a portion may be introduced through the insect screen 120 .

Therefore, only the HEPA filter 136 does not allow outdoor air to flow into the room, but some air flows through the insect screen 120 , so ventilation is maintained and ventilation can be made possible.

Of course, in some cases, the HEPA filter structure 130 may be separated from the insect screen frame 110 to increase the ventilation rate, so that the indoor ventilation can be performed well.

On the other hand, if the HEPA filter 136 is contaminated by fine dust due to long-term use, the function as the HEPA filter 136 cannot be exhibited. In this case, the HEPA filter structure 130 is separated from the insect screen assembly 100 and It can be used again after washing.

That is, a magnetic material 137 is provided on the outer surfaces of the first support frame 131 and the second support frame 132 constituting the HEPA filter structure 130 , respectively, and the first frame 111 of the insect screen frame 110 and the Since the second frame 112 is provided with a magnetic force attachment member 116 attached to the magnetic body 137 , the HEPA filter structure 130 can be easily separated from the insect screen frame 110 .

Therefore, the present invention can prevent fine dust from entering the room by opening the window 20 only as much as the area of the HEPA filter structure 130 on a day when there is a lot of fine dust. Ventilation and ventilation can be achieved by opening the window 20 to a position where the entire area is opened.
