Miele Triflex HX-FSF-2 Fine Dust Filter 11945240

The Triflex HX-FSF-2 Fine Dust Filter (part# 11945240) is the genuine Miele fine dust filter for the Triflex HX3, Triflex HX2 and Triflex HX1 Facelift cordless stick vacuums.

What the Triflex HX-FSF-2 Fine Dust Filter Does

The fine dust filter sits inside the dust container assembly and traps the fine particles that get past the separator, protecting the motor and keeping the exhaust clean. The Triflex HX3 cleans this filter automatically with ComfortClean, but over time the pleats wear and the filter loses efficiency. This refreshed version fits every Triflex HX3 — including the Cat & Dog, Plus and Aqua models — as well as the Triflex HX2 and HX1 Facelift.

When to Replace the Triflex HX-FSF-2 Fine Dust Filter

Miele recommends changing this filter every three years to maintain performance. Replace it sooner if suction stays low after emptying the container or if the filter is torn or no longer seals.

The original first-generation Triflex HX1 uses a different filter, the HX-FSF.
