New home for us and I've never seen anything like it before. My previous filter had a standard cardboard frame and a filter that you just popped in and out and threw away when you were done. These filters require a "pleat pad" to hold them in place. When I found out about this I went online to buy a set of spacers. I found out they were $50 to $80 a set so I ditched those filters and bought what was in the oven before.
