I love the filters, but I have a manufactured home, with a down draft furnace, and I have to trim off the sides of the filters to make them fit. I only have a 5/8 gap. I wish someone made a good filter, like Filterbuy, that would fit without cutting,and trimming.
Always happy with my filters from filter buy. but this time they came smushed inside the filter frame. like there was an assembly error. surely will affect efficiency. but i will be back as every other order has been perfect.
