NICE
Reminds me of a story!My dads a Heating and Air Conditioning/Electrician man and he was out on the job one day or one of his service techs was and went to a black guys house for a service call.Well when he checked the unit he came to find a piece of cardboard with holes stabbed all in it that the black guy had put in there cause he had no filter and guess he figured he would make his own.Only issue is with cardboard wheres all the dirt and filth go to, do to its not got no places to catch it at like a filter.
