Do you mean remove ALL filters from all clips in a Sequence or specific filters from multiple clips?
If it's former:
Right click on selected clips and choose "Remove Attributes".
If it's the later, it's not easy, but here is a possible workaround:
1. Remove the specific filters from one clip
2. Follow the step above to remove all filters from the rest of the clips
3. Copy the clip that has the filters you wanted to keep
4. Use the Paste attributes feature on the remainder of the clips to reapply the filters you want to keep.
Hope that helps
