Where should the "unselect/unclear filter" icon go?

I am designing a major component of my soon-to-be website: the listings header where I provide users a magnifying glass to filter out records according to the Loading/Delivery/Tag options trio. (I don't mean the funnel filter in the upper right corner).

Listings header

My issue is with where to position a Reset option.

If I don't have such a reset option it will make it more difficult for the end user to reset the list and he/she would be more than likely to hit the browser's back button to return to the last all-records-shown list.

That's the kind of behavior I want to avoid. So, where should that icon go? What would be the best position for it?
