VBA Excel unfilter item using autofilter

Hi All,

I want to write a VBA macro code in Excel, that can unfilter particular item(s) (say "Peter"), how can I do that?

Below is the script for filtering items, I need the unfilter version, thanks!

ActiveSheet.Range("$A$1:$K$100").AutoFilter Field:=1, Criteria1:=Array( _
        "Alan", "Brenda", "Cathy", "="), Operator:= _
        xlFilterValues
