Stupid Question / Air Filters

Some genius builder in our new home decided it was a great idea to have 3 different air filter sizes for the HVAC. Even better, one of them is a near impossible to find size: 16 x 36 x 1. I initially purchased a pack of them on Home Depot, but now they don't seem to be available. I can purchase them on Amazon and a few other places, but because they are tough to find they are several times the price of "normal" size filters. So stupid question: has anyone tried putting TWO filters together to sum the size of ONE unusual size? I'm thinking I could put a 16x16 & 16x20 stacked and maybe it would get the job done, be easy to get and be half the price. But maybe this isn't a good idea.
