That "better" air filter might be making your house wetter.
A high-MERV filter restricts airflow. Less air across the AC coil means less water pulled out of the house, and in this climate a dense filter can add 5 to 10 points of indoor humidity on its own.
Down here, airflow beats filtration. Use a MERV 4 or 5.
