Would you look for a clear all filters button on each individual filter?

On this said page there are 4 filters, here is the current design of the drop-down filter. However if you were to select say 20 of the 40 would you be looking for a "Clear Filter" button? The cancel button just closes the dropdown and does not change the current selection or should that also clear selected filters?

I could add one in however what would the best order be? "Apply" "Clear Filter" "Cancel"?
