Replacement Pre Filter for Tineco A10/A11 Hero/Master.
The Pre Filter is crucially important for suction power and suction efficiency, you need to deep clean or replace the filter periodically to prevent suction loss.
The Pre Filter is rinsable, please rinse under cold running water, then give it 24 hours to be dried completely before reinstalling.
Compare to traditional rinsing, Tineco Patented Pre-Filter-cleaning Tool will be highly recommended, which offers a 10sec convenient deeper clean solution to get you suction back! More details on Tineco Rinse-free Cleaning Tool page.
