Best way of doing it
Below code is to copy the visible data in DBExtract sheet, and paste it into duplicateRecords sheet, with only filtered values. Range selected by me is the maximum range that can be occupied by my data. You can change it as per your need.
Sub selectVisibleRange()
Dim DbExtract, DuplicateRecords As Worksheet
Set DbExtract = ThisWorkbook.Sheets("Export Worksheet")
Set DuplicateRecords = ThisWorkbook.Sheets("DuplicateRecords")
DbExtract.Range("A1:BF9999").SpecialCells(xlCellTypeVisible).Copy
DuplicateRecords.Cells(1, 1).PasteSpecial
End Sub
