Abstract: A filtration device is provided whose body member has a transparent or translucent part (i.e., window) so that a user can directly see the colors of the filtering agents inside. If the colors of the filtering agents are changed due to the loss or degradation of functionality, the filtering agents can be replaced so that the performance of the filtration device is consistently maintained.
