Purolator He-E 40 Pleated Filter
Your review: This is the only furnace I have found that will fit in my furnace (because of the actual size of 13 1/2" x 24 1/2"). Every other one I have found is a quarter of an inch larger and they don't fit my furnace. I used to be able to buy them at one store in the area, but they no longer carry them. Really glad I was able to get them through you.
