With the Spit 654699 hepa filter set, you keep your workspace clean and protect your dust extractor motor from hazardous fine dust. This two-piece set of genuine hepa filter cartridges is designed specifically for Spit dust extractors, including the AC1600, AC1625, AC1630 P, AC1630P M, and AC1630P h models. During demanding drilling, grinding, or drywall sanding jobs, you reliably capture microscopic dust particles. By replacing both filter elements at once, you maintain steady airflow and ensure your vacuum delivers maximum suction power.
