The loss ensured Wales coach Warren Gatland's poor record against New Zealand, Australia and South Africa continued.
But, with all three sides visiting the Millennium Stadium for the Autumn series in November, North, believes Wales must capitalise on the pain.
"We were devastated after the second Test," North, who played three times during the Lions' 2013 tour, told Rugby World.
"It was such a difficult defeat to take because we were dominant for so much of the game.
"If we can take a positive it showed we can go toe-to-toe with one of the world's best sides.
"We have to believe we can kick on from that loss in the same way Ireland did after their last minute loss to the All Blacks.
"Hopefully being at home with the fans behind us will give us the edge needed when New Zealand, Australia and South Africa come to the Millennium Stadium in November."
