PURPOSE: A water filtering apparatus is provided to filter water in a sealed container by controlling inside and outside pressures of a filter by allowing only air to pass through by installing a cover layer with a hole in a lower cover. CONSTITUTION: A water filtering apparatus comprises a carbon filter(110), a lower cover(130), and a cover layer (140). The carbon filter is formed of an activated carbon, and a pore is formed in the carbon filter to filter water. The lower cover blocks an end of the carbon filter and has a hole allowing air to pass therethrough. The cover layer blocks the hole when the water filtered by the carbon filter is pulled in and allows air to be discharged through the hole when the air is injected into the carbon filter. An accommodating unit(111) is formed inside the carbon filter, and the carbon filter further includes a membrane filter(120), which is installed in the accommodating unit. |
