What i am mentioning about is not the metal filter. It looks like a sheet of sponge. I'm using such kind of a hood, for the first time. Its already soaked in oil, haven't found a replacement yet. Tried in Coop and Migros, but in vain. Desperately in need, please help.

Ikea sell a few - obviously to fit the hoods they sell - you may be lucky and find one to fit yours

We buy them at a Migros shop, MM size. Migros Wiedikon has them, for example.

I've tried in Migros, but firstly, i'm not getting a site of such a thing over the shelfs of the supermarket. The second thing is i cannot make anyone there, understand what i'm really in need of. Any help with putting them in words (Schwiizertüütsch) would be appreciated.

Because I like your avatar I've gone to the cellar and made a photo of our "Filtermatte für Küchen-Dunstabzugshauben", Price 3.50 Fr., Format 58cm x 50cm (you can cut them). Just ask for a Filtermatte for the kitchen and they should know what you're talking about. You should find one on the shelves with cleaning or kitchen products.

Can also be had at any FUST or Media Markt store. You get the package that contains three or four which can be cut to size. In addition I usually use two of the cut portions and hav two extra filters. I believe the cost is around 9chf

Thanks a lot mate. Finally i got it from migros. Your help is very much appreciated.
