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.
