Will HEPA filter fix it?
Only after the unit interior is cleaned — then maintain filters monthly.
Why Your AC Is Blowing Dust
Dust from the vents means buildup on the blower and coil — the fan pushes it into the room.
AC blowing dust happens when the blower wheel and coil are coated with debris. Filters alone don’t remove existing internal buildup.
