Neff cooker hood (by 2 users)

the manual i have says that the charcoal filters inside need changing about every 6 months. take out the grease filters then you should be able to turn it and take them out. you may not have these if the extractor vents to the outside. the grease filters can be cleaned with a neutral detergent and then put back in. Make sure the electric is off before you do any of this. Hope this makes sense and helps!
