It only comes in one size for the home so people that buy it for their Furnace cut it to match the size of their old filter. It is very sturdy and looks to be quite well made. It will trap allergens & critters much much better than the OEM filter and has higher airflow and costs less, and is much much better than the OEM filter

At Home Depot for about $8-9 you can get the base line or "RED" 3M filter home ac/furnace air filter. With this filter you get 4 chances at making a replacement filter to get rid of that crappy OEM filter wannabe. You might as well get the biggest size filter of that level, remember to get the RED and RED only class filter by 3M, none of the others I saw at Home Depot were sturdy enough to make this project work. They all should be the same exact price for this level of filter from 3M, at least it was at my Home Depot. Anyway, you need to take the old OEM filter out and place it on top of the new 3M filter in one of the 4 corners. It has a arrow showing the proper direction of airflow, if memory serves me the little wire mesh backing goes towards the blower motor itself, or towards the passenger side of the car on G2 Legends. Since this filter or any other like it isn't sturdy enough on its own to hold up to the forces generated in any Forced Air system, it has cardboard backing all the way around it, as well as some little cardboard strips going over the entire filter in a X type of pattern if my memory serves me.
