Excel Or in If Not Working

In Excel, I am simply trying to delete a row if cells in column V is not equal to F or V. This code deletes everything. It has to be something stupid, but I can't see it. Please help!

For i = RowCount To 1 Step -1
     If Range("V" & i).Value <> "F" Or Range("V" & i).Value <> "V" Then Rows(i).Delete
Next i
