PURPOSE: An alarming apparatus for informing the replacing timing of a water purifying filter is provided to recognize the replacing timing of a water and to reduce noises by alarming sounds when a user uses a water purifier. CONSTITUTION: An alarming apparatus for informing the replacing timing of a water purifying filter includes a purified water amount detecting part(20), a controlling part, a displaying part, an alarming part(23), and a resetting switch(27). The purified water amount detecting part is installed at a water path in order to detect the amount of feed water. The controlling part continually adds the amount of purified water detected by the purified water amount detecting part. The controlling part compares the added amount of purified water and the limited amount of purified water of filters to verify the respective replacing timing of the filters. The displaying part adds the amount of purified water output from the controlling part and displays the amount of purified water on a displaying window. The alarming part operates if the amount of purified water is more than the limited amount of purified water and a water purifier is used. The resetting switch resets the limited amount of purified water.
