Exclude traffic if three conditions are true

I have a spike in my report and I have found out the reason is traffic with these conditions

  • Session default channel grouping=Direct
  • City= Dublin
  • Day=28

So I want to filter out this traffic but I cannot find the right filter logic. OR and AND work only well if I want to include the traffic.

Is there a way to say all three conditions must be true and then filter out this traffic?
