Shark Navigator NV42 Upright Vacuum Foam Filter, 3-Pack MC-5240 airflow falls and fine particlesThis replacement Shark foam filter (Part #F657) fits the Shark Navigator NV42, NV44, NV46, and UV402 uprights. It sits ahead of the motor, trapping fine dust before it reaches the motor and wears it down.
