Miele Tri-flex Filter Housing – Part #11509681

OEM Filter Holder & Airflow Chamber for Miele TriFlex HX1 & HX2 Cordless Vacuums

11509681. This OEM housing securely holds the filter in place, directs airflow correctly through the filtration system, and ensures your vacuum operates at peak performance.

A cracked, warped, or damaged filter housing can lead to poor suction, dust bypass, rattling noises, or an improperly seated filter. Replacing the housing restores the vacuum’s precision airflow and keeps fine dust where it belongs—inside the filtration system.

Why This Filter Housing Is Essential

Ensures Proper Filter Positioning

The filter housing:

• Holds the filter firmly in place

• Prevents shifting or dislodging during use

• Ensures proper sealing around the filter edges

• Maintains correct airflow direction

An improperly seated filter can reduce cleaning performance and air quality.

Protects Internal Components

With proper airflow management, the housing helps:

• Prevent dust from entering the motor chamber

• Reduce filter stress and premature clogging

• Maintain stable suction power

• Improve long-term vacuum reliability

Cracks or warping can disrupt airflow and cause internal contamination.

As a genuine Miele part, this filter housing delivers:

• Exact fit for TriFlex HX1 & HX2 systems

• Durable molded construction designed for daily handling

• Heat- and impact-resistant materials

• Seamless integration with the vacuum’s multi-configuration design

No adjustments or modification required—perfect factory fit.
