Step-by-Step: Replacing the Shark Apex DuoClean AX912 Pre-Motor Filter
⚠ Common mistakes on the Apex DuoClean AX912
The AX912 mistake is washing the foam and skipping the felt disc under it — the felt is what clogs. The second is refitting either while damp, which strains the motor.
✓ OEM vs aftermarket for the Apex DuoClean AX912
The foam/felt pre-filters are generic across Shark uprights, so aftermarket multipacks are great value — confirm the listing names the AX912. Keep a spare set for while one dries.
