I've tried several brands, multiple smokes each with various pipes and blends. I find there is some variation in width between brands. Some notes:
1. Thinnest is Vauen
2. Thickest is White Elephant
White Elephants are so thick, they do not fit in some pipe brands.
Ideally, filter should fit snugly. I find filters expand somewhat in width during a smoke. Probably due to absorbed moisture.
I think it's OK to use a "too narrow" filter without fear of unfiltered smoke reaching the mouth because breath draws the filter tight against the mouthpiece air hole opening.
I find them all of good quality with one exception:
3. Dr Pearl Junior -- I tossed my remaining stock after becoming convinced they do not filter as well as the others. I believe this is the oldest, and original brand.
Best value:
4. Scotte on Amazon -- I believe these are made in China. I find the quality to be as good as any. Perhaps all brands are made in China?
Please add notes from your experience with various brands.
