Where is the cabin air filter on a 2011–2014 Hyundai Sonata?

Behind the glovebox; drop the glovebox door, ~5-minute DIY.

How often should the cabin air filter be replaced on a 2011–2014 Hyundai Sonata?

Every 15,000 mi (more often in dusty conditions). Sooner if you drive in heavy traffic, on dirt roads, or through wildfire smoke, a clogged filter shows up first as weak airflow and a foggy windshield that will not clear.
