I'm not sure I understand your problem but you can just detect when up is clicked like this:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            doSOmething();
            return true;
    }
    return super.onOptionsItemSelected(item);
}

If you intercept the up click, you can presumably do anything you want here. Returning true will consume the event and that should prevent any default action from taking place. This way you can do whatever you want the up button to do while at the same time consuming the up event to prevent clearing of your filters.
