Welcome to the forum!
You will find that the filter debate is ongoing and with no end in sight. Some swear by filters, some detest them. As for me, some of my pipes take filters and some don't. I use a rock maple insert for my Brigham and its great. I have a Christmas 2016 Peterson and some Vauens that take a 9mm charcoal filter. I find that they really restrict the draw for me.
But like anything else pipe related, do what works for you and your pipe.
Happy piping!
