It's not the prettiest of things.
But boy does it work. Can't fit an extractor in our kitchen, and food smells were getting upstairs.
Have now tested it on curry ,stiry fry and bubble and squeak. I run it while I was cooking and so far an hour after which is not a problem as it is very quiet. So far no smells have got upstairs and it near enough clears the cooking smells in the kitchen.
If ran it longer I'm sure they would completely disappear as well.
Was sceptical that it would work But with the money back guarantee though it was worth a go .very very happy that I did.
Thank you
