Tefal Compact Power TW3927 – Plus.Parts® Spare Dust Bags

In any bagged vacuum, the replacement bag is a functional component, not just a waste container. The bag material acts as a secondary filter layer, and the seal it forms with the inlet collar determines how consistently the motor draws air through the debris bed. The Tefal Compact Power TW3927 is a compact cylinder vacuum where that relationship is direct: fit the correct bag, and suction remains consistent through the full capacity range; fit a bag with loose tolerances or insufficient density, and the airflow path degrades as the bag fills, reducing effective pickup before the bag is actually full. Changing bags on schedule matters too: an overfull bag restricts airflow significantly, adding motor load and reducing the cleaning power the TW3927 delivers on its rated setting.

This six-pack provides the ongoing supply for the TW3927. Each bag is a Plus.Parts® spare dust bag sized to the TW3927 chamber and inlet specification, seating correctly without modification and maintaining the sealed airflow connection through the bag’s full working life. The bag material is robust enough to hold its shape under the motor suction load, reaching genuine capacity before the material begins to restrict airflow.
