AR-X100 + Tiffen filter WR?

Hi!

I've owned the camera for a few weeks and absolutely love it. As I shoot in a variety of environments (trail running, hiking, bikepacking, etc) I've also bought the AR-X100 and PRF-49 filter to make it WR. I'm eyeing on the black pro mist 1/8 filter from Tiffen.

Do you know if the camera will still be WR with this filter? Or is it only the combination of the AR-X100 and PRF-49 filter which prevents moisture and dust?
Thanks a lot for the help!
