Yes, if u leave it off fresh air from outside will come in. This is ideally the normal way ur ac should work, but here in Nigeria the air from outside is polluted so if u leave the recirculation button off within 3 minutes u would already feel the bad air fro outside (coupled with dirty cabin air filter that most people don't check). At the end leaving it on is the best option in Nigeria.. but in countries that care about the air around them and with low humidtiy, it is better to leave it off and get fresh air.
