Complex filters - grouping 3 filters together

Content

I want to create a complex filter which requires grouping 3 filters with another set of filters. I have played around clicking the AND / OR to get the combination, but it has not worked so far. Can someone point me in the right direction ?

This is what I am trying to achieve

Filter 1

AND

(

(Filter 2 AND Filter 3)

OR

(Filter 4 AND Filter 5 AND Filter 6)

)

Thanks in advance !
