Select AD object according to lastpassword changed date

Hi

I have a PS command that search for AD object displaying the name and password last set property

"Get-ADComputer -filter * -Properties * | Select-Object name,PasswordLastSet"

the command returns the name and date and time stamp but I would like to refine further to give me only the object that changed password from say "01/09/2014" and upward. 

How can I search for these object?

many thanks
