Product review (1 stars): Poorly Designed
Poorly designed product.  It is supposed to fit into a ducted meshed filter but it is too large and as others have mentioned sits too high and impedes the fan.  I had to "bend" the wire filter to accommodate this charcoal filter to the maximum extent.  Wasn't difficult to do but the possibility of damaging the wire mesh filter is there and it should not have come to that.
