Filter Formula to Exclude Fields

[mustufa2019]

I am trying to use the filter formula to exclude accounts starting with "Model..." within the Operator Name; see screenshot 1 below:

I tried using the below formula (see screenshot 2) but it didn't work. Any help would be appreciated.

Just use "MODEL", you don't need the .*

or 

left([operator name ],5) = "MODEL"
