Hoover Primary Filter for Air Ultra Bagless UH72430 (Non-HEPA) CV1004B Function: Cyclonic dirt/air separation chamberThis genuine Hoover primary filter is made for the Air Ultra bagless upright, model UH72430 (Part #440005633). It is a standard non HEPA primary filter that sits at the core of the filtration system, capturing dust and debris from the dust cup's airflow before it passes toward the motor and exhaust. Because the Air Ultra is a bagless vacuum, the primary filter works on every pass and steadily loads with fine dust, which weakens suction as it clogs.
