Does anyone have the Asko stackable ventless W/D ?
How often should you clean the filter in front and the one in back of the dryer ?
There are not many ventless dryer users on this forum and I bet very few, if any, have an Asko. It might be a good idea to check on the Asko web site for the dryer user's manual, if you don't have one. Or call their customer support number.
