How to prevent row check being skipped when the previous row is checked and deleted?

This is intended to loop through two columns and verify that the value in the L column is lower than a specific (single) value in a cell from another sheet. It also checks to see if there is an "#N/A" error in the cell on the same row in column M. If these are true then the entire row is deleted. The code below appears to work, however, I have to run the For loop multiple time to get fully delete all the rows. My hunch is that when a row is deleted it's not checking the one right below it and moving on. How can I avoid this? Any help is appreciated.

Sub removerows()

Dim wsOut As Worksheet
Dim wsPrev As Worksheet
Dim r As Long
Dim Lastrow As Long

Set wsOut = Worksheets("Output")
Set wsPrev = Worksheets("Previous")
Lastrow = wsOut.UsedRange(wsOut.UsedRange.Cells.Count).Row

For r = 2 To Lastrow
    If wsOut.Cells(r, "L").Value < wsPrev.Cells(2, "L").Value And _
        Application.WorksheetFunction.IsNA(wsOut.Cells(r, "M").Value) Then
              wsOut.Cells(r, "L").EntireRow.Delete
        Else
            wsOut.Cells(r, "L").Interior.ColorIndex = 20
    End If
Next

End Sub
