Column with data separated with semicolon

[Revilo]

Hi,

Just want to ask, I have a column in one of my table with format shown below. Is this an array? I am interested in counting rows with blank specific string within that array.

Ex. 

I am interested only with "followups", if its not present then I will count that specific record with no string of "followups".

Hi @Revilo 
I hope it is as simple as it is described by the given example. Please let me know if it is not. For now please try

=
COUNTROWS (
    FILTER ( 'Table', NOT CONTAINSSTRING ( 'Table'[Equipment], "followups" ) )
)

[Revilo]

=
COUNTROWS (
    FILTER ( 'Table', NOT CONTAINSSTRING ( 'Table'[Equipment], "followups","appliances", "clothing" ) )
)

can i add more strings in that parameter like the shown above? thanks

=COUNTROWS(FILTER(TABLE,SUMX(Array,FIND(TABLE[Equipment],Array[Col],,0))=0))
