Mask Apparatus {MASK APPARATUS}

The present invention relates to a mask device.

In general, a mask is a device that covers a user's nose and mouth to prevent inhalation and scattering of germs, dust, and the like. The mask fits snugly against the user's face to cover the user's nose and mouth. The mask filters germs, dust, etc. included in the air flowing into the user's nose and mouth, and allows the filtered air to flow into the user's mouth and nose. Air and germs, dust, etc. contained in the air pass through a mask body formed of a filter, and germs, dust, etc. are filtered by the mask body. However, since air flows into the user's nose and mouth after passing through the body of the mask or flows out to the outside after passing through the body of the mask, the user's breathing is not smooth. Recently, a mask equipped with a motor, a fan, and a filter has been developed to solve the above-mentioned problems.
