Rancho San Diego is SR-94 corridor hillside residential, Cuyamaca College-adjacent 1980s-90s tract systems hitting first major replacement, with extreme East County summer heat (100-108°F) and SDG&E high-risk fire zone designation driving heat pump conversion plus battery-backup interest.. East County homes benefit most from whole-home air cleaners during fire season and Santa Ana dust events.

What MERV rating should I use?

MERV 11 is the minimum that actually catches meaningful fine particulate. MERV 13 is the sweet spot for allergens, pet dander, and wildfire smoke. MERV 16 filters in a proper 4-inch cabinet are excellent, but a 1-inch MERV 16 in a standard slot usually chokes airflow. Always pair high-MERV with adequate filter area.

Do UV lights really work?

For coil mold and airborne pathogens in the air handler, yes, UV-C directly on the coil is proven. For whole-home sterilization of breathable air, the evidence is weaker. We recommend UV-C on the coil, not as a standalone air purifier.
