Yes, Dr Pearl can shuttle to and fro in some pipes giving an odd thocking noise, but I've always found them the most reliable choice. Oddly enough, I got a box of 250 White Elephant charcoal when I bought my latest Chacom. I'm hoping they'll be compatible..Thank you for your reply and for the tip regarding troublesome charcoal granules -- different brands of filters do feature different number/size/shape air holes at each end.
Variation in 9mm filter width is an interesting topic. I have identified three variations, from wide to narrow:
white elephant, everybody else, and Dr. Pearl.
Dr. Pearl, being narrowest, will fit any 9mm filter pipe, but I don't like how the filter moves back&forth in pipes other than Vauen, so I wrap some scotch tape around the filter, so that it fits snug, and prevents smoke from slipping around the filter.
On the other extreme, white elephant filters are too wide for my Vauens, and my Chacom!
I normally buy Dr Pearl in boxes of 180 but they didn't have any so fingers crossed the WE will do the job until after the new year. Spent up for now..
