I was assigned to operate flight to ZZZ. I was the Pilot In Command and was the Pilot Monitoring during this flight. While on the STAR going into ZZZ; we just passed through approximately 19;000 feet MSL. At that time; my First Officer and I both looked at each other and asked if we smelled something. Both of us agreed that it smelled like a wet or dirty sock in the flight deck. Based on other information I have received from other pilots flying this type of aircraft; and other types of aircraft; I assumed it was potentially a fumes event we were experiencing. I immediately pulled my quick donning oxygen mask out and donned it. I called back to the flight attendants and asked if they smelled anything unusual to which they both said no. At that time and knowing that PACK 1 generally supplies air to the flight deck and based on our altitude of approximately 16;000 feet MSL; I told my First Officer I was going to turn PACK 1 off; to which I did. We continued the descent and after approximately 3 minutes; I took my mask off to see if I could smell the odor anymore; to which I could not. I told my First Officer that we will continue with the arrival and approach and once we land; we will write up the airplane; to which I later did. The remainder of the arrival and approach was conducted without further incident and no emergencies were declared. Based on these continual and potential fumes events; I highly recommend that [Company] along with other airlines; develop a QRC checklist for these type of odors.
EMB-175 Captain reported a 'dirty socks' odor during arrival. Odor dissipated after turning Pack 1 off.
