Asko range hood grease filter notice — read this important safety alert for full details and affected models.
Saturated grease filters in Asko range hoods are a direct fire ignition source if a cooktop flame flares up or if the range hood motor overheats — cleaning or replacing grease filters every four to six weeks is essential in households that cook with oil regularly. Asko CO-series and ceiling-mounted range hoods use stainless steel mesh grease filters that are dishwasher-safe and reusable, simplifying maintenance when done on a regular schedule.
A visibly yellowed or dripping grease filter is already a fire hazard. The accumulated cooking fat can ignite from a high-heat pan or a brief burner flame that contacts the hood body. Regular filter maintenance also preserves the hood’s extraction efficiency and prevents grease from migrating to the motor and impeller where it is much harder to clean.
Warning Signs to Look For
- Grease filter appearing yellow, brown, or showing visible drip marks
- Grease dripping from the hood body onto the cooktop or range below
- Reduced extraction airflow despite no change in fan speed setting
- Hood motor running louder than usual
- More than six weeks since the last filter clean
Filter Maintenance Steps
- Switch off the range hood and allow it to cool.
- Slide or unclip the grease filter panels from the hood body — Asko CO-series filters release with a simple push-tab mechanism.
- Place filters in the dishwasher on a 60°C or higher program, or soak in hot water with a degreasing dish soap for 20 minutes before brushing clean.
- Allow filters to dry completely before reinserting — a wet filter restricts airflow and can cause motor strain.
- Wipe the interior hood body, especially around the fan inlet, with a degreasing cloth while the filter is removed.

When to Call a Technician
If the hood motor is unusually loud or intermittent, if grease has visibly reached the impeller housing, or if the carbon filter in a recirculation model emits odors after replacement, contact an Asko-authorized technician for a professional internal degreasing service.
