About the Shark Apex DuoClean AX912
The Shark APEX DuoClean AX912 corded upright uses washable foam + felt pre-motor filters under the dust cup, plus a HEPA post-motor filter. This page covers the foam/felt pre-filters — the ones that clog first and cost you suction.
The AX912 foam and felt pre-motor filters are reusable; rinse and reuse until the foam crumbles or the felt tears. They're distinct from the post-motor HEPA — a different part on a different schedule.
✓ Buying Advice
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.
⚠ Common Mistakes
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.
