PURPOSE:To provide a filter for a ventilating fan, which can be repeatedly used by the replacement of its main part and has favorable disposability, and thus the filter is easily treated when turned into a refuse and the maintenance cost can be reduced. CONSTITUTION:A filter for a ventilating fan is so composed that a frame body 1 holding a filtering element 2 for filtering passing air is made of reusable metal and that the filtering element 2 is made of combustible material which can be burnt up and is replaceable for the frame body 1. In this way, the frame body 1 can be repeatedly used by the replacement of the filtering element only, and since the filtering element having been used up can be burnt up, waste disposal is made easy and the maintenance cost can be also reduced. |
