Midea 12175000A47380 HEPA filter for C5

Midea 12175000A47380 — cordless stick vacuum HEPA filter for the C5. A stick vacuum filter does two jobs: it keeps fine dust inside and protects the motor from abrasive grit. Clogged, it first eats the suction, then heats the motor, and only after that does the cleaning result give it away — which is why it is changed by the calendar rather than by how it looks.
