Reviews for ductless Chimneys

As of now, I can find only beyond appliances for ductless chimneys. Since we don't have heavy usage we thought to go with ductless. Any other recommendations on ductless chimneys? I saw few faber chimneys with both duct and ductless options but again saw a review saying it's difficult to get the filters. so, it beyond appliances ductless chimney is only my option here?
