It's fine. I bought it for my aunt, who has an old ductless extractor (chimney). She told me that she hasn't had any odors since then, everything is okay. It also includes a simple filter (the "white" one). The size of both filters, both the carbon and the simple one, allowed me to cut them in half and use only half of them. It arrived almost at the limit with minimal stretching and covered the holes that this specific extractor has. So, there is another set for future replacement. At that time, I didn't take any photos to upload them now...
