DISTINCT FILTER one table by another table

[ericOnline]

I'd like to create a new table, derived from filtering an existing table by another existing table using DAX only. (I do not want to use a calculated column).

Is this possible?

Example:

- I created a relationship between T1[ID] and T2[ID]

T1: (existing)

THING_ID	VAL	VAL2
1	X	Y
1	X	X
2	Y	Y
9	Y	Z
9	Y	Y

T2: (existing)

THING_ID	VAL	VAL2
1	A	AA
2	B	BB
3	C	CC
4	D	DD
5	E	EE

Something like:

T3 = 
    DISTINCT(
        SUMMARIZE(
            FILTER(
                T1, T1[ID] NOTIN T2[ID]
            ),
            T1[ID],
            T1[VAL]
        )
    )

Desired Results:

T3: (new)

THING_ID	VAL
9	Y
9	Y

I think this does it. Please test at your side

TableT5 = CALCULATETABLE(TableT1, NOT( TableT1[THING_ID] IN VALUES(TableT2[THING_ID])))

Also, in Power Query, you could Merge the two tables using a Left Anti Join on THING_ID

@HotChilli ! Thank you! That worked. Very elegant solution compared to what I found when researching. 
Do you know how to add subsequent conditions?
Example: Want to also exclude BLANKS(). 

Added: && NOT(BLANK()) but empty results still showing. 

Whats odd, is they don't appear to be BLANK() but rather empty strings. I tried && NOT(""), but they still showed up.
