The Duoflex HX1 HX-FDF 20 Fine Dust Filter (part# 12518910) is the genuine Miele fine dust filter for the Duoflex HX1 cordless stick vacuum.

What the Duoflex HX1 HX-FDF 20 Fine Dust Filter Does

The filter traps fine dust after the Duoflex’s separator so the motor stays protected and the exhaust stays clean. The Duoflex HX1 is no longer sold new, but this filter is still available for owners keeping their machine running.

When to Replace the Duoflex HX1 HX-FDF 20 Fine Dust Filter

Miele recommends changing it every three years to maintain performance, or sooner if suction stays weak after emptying the dust container or the filter is torn or no longer seals. Note that the replacement filter is supplied without a lid — reuse the lid from the filter you are replacing.

This filter fits the Duoflex HX1 only; Triflex filters are a different part.
