Kitchen extractor filter | Smeg grease filter

The Smeg grease filter in the kitchen extractor unit had been doing it’s job and was absolutely blocked with grease and cooking deposits. After searching the internet it seemed that to replace the filters was going to cost in the region of £80+ so I then found some kitchen hood grease paper for £3
After a hour or so the filters were replaced and the £73 I saved was put in the tool kitty ;-)
