A debut hat-trick from Serge Gnabry, a Jonas Hector double, goals for Sami Khedira and Kevin Volland and an own goal saw Germany cruised to victory over the country ranked 201st in the world.
The reigning World champions have won their opening four group games without conceding a goal and sit five points ahead of Northern Ireland.
Although there will be sterner tests to come in Group C, Low said Germany are meeting the challenge he set them.
“After the World Cup win it was not so easy, and we have not always met our standards,” Low told the DFB website.
“That is why we have said before the World Cup qualifying that we want to dominate the group from the start and we have managed so far.”
Germany travel to Italy for a friendly on Tuesday and their next World Cup qualifier is away at Azerbaijan in March.
