potato chips crumb got into macbook air vent. What do I do?

So I was just eating some potato chips in front of my macbook air 13'' and suddenly a small piece of the chip (about 1/5'' in length) bounced into the air vent through the gap between the screen and the keyboard. I tried removing it using a compressed air duster but the more I tried the deeper it got stuck. Right now it should be very deep inside the vent and I cannot see it. That crumb is probably very oily and I'm not sure if it will damage the internal electronics. Should I bring it to the repair store? Or should I worry about it at all? Does mac vent actually has some filter that can prevent big particles getting into the electronics?
