how to clear Blox filter every time I switch Tabs (tabber )

Hello, I have a dashboard that uses a tabber to shows different dashboards. I also have a different filter under each tabs in tabber. I was wondering if there was a way to clear the filter every time I switch tabs. At this moment, I get no data ( or wrong data) every time I switch tabs because the filter stays on when I click the next tab which is supposed to filtered by a different item. I am using a dropdown blox widget to filter each tab.
