Looks like the original Canadian ones are now gone. Canadian ones said "Honeywell" on them; new ones have no maker's name.
The new American ones are visually the same as the Canadian ones except that the holes in bottom are more oval than round. The holes are larger than the ones in the Filtech filters.
