Efficient way to filter and delete junk records

Hello,

I have a large dataset and trying to filter and clean some junk records from it as part of a macro.

Current method is to loop through each row and delete if it's junk - this is taking too much of time and wondering if there is any efficient way.

Here is a the snapshot of the code-

'Loop from the Lastrow to Firstrow (bottom to top)
For Lrow = Lastrow To Firstrow Step -1
    'We check the values in the "O" column and delete if the WS_Load percent is 0
     With WSP.Cells(Lrow, "O")
        If .Value = 0 Then .EntireRow.Delete
     End With

Next Lrow

Appreciate you help.

Thanks, Anil
