Wow, I never knew that. 
My apologies @ScubBart. I have literally just set a filter off and then back on and left the filter alone.
However in my testing, after setting filteron to False, if I use Toggle Filter from the ribbon, the filter is set again.
So I tested this from the command window and I get the filter still set?
Code:
docmd.OpenForm "frmPressure",,,"pressureID <30"
forms!frmpressure.filteron = false
? forms!frmpressure.filter
pressureID <30
