In no particular order ..... \n\nAt low frequencies the necessarily high values of L and C can result in an inconveniently large size.  \n\nAn active filter, which can be designed to exhibit and work with higher impedance values means that smaller values of C can be used.\n\nAdditionally the use of a gyrator configuration can eliminate the need for L.\n\nA passive filter is inherently lossy, at least to some extent.\nAn active filter can have gain.\n\nAn active filter is usually smaller than a passive one.\n\nA passive filter doesn't require a power source.
