Seems like I've heard of people doing this. Is it OK to make your own lawn mower filter out of a paper style home AC register filter? Crazy that my 4"x4" lawn mower filter is $7, yet the 20"x30" for my house is $1-$2.
Make own lawn mower filter?

Sure. But is it worth saving $5 is your homemade filter doesn't fit quite right and it sucks dirt into the engine?
You're not just saving $5 though. You could probably make 30+ filters out of that one home filter. If you overlapped and had the filter hanging out of the edges, there's no way dirt could get in.
If your filter does not create the proper back pressure then the mower will not run correctly. Stop being a cheap ass and get the right part. I love how people will risk damaging something expensive to save a few dollars.
I have that same filter in my mower. I simply take it out occasionally and blow it out with compressed air in the opposite direction of normal flow. They last quite a while that way.

I don't know if you'll be able to find any media that can filter as well as that.
EDIT: Or is as durable and long-lasting.

Having a filter that obstructs intake flow may cause a problem. That will cause increased vacuum and change the mixture of gas/air. Ronstang apparently knew that but did not verbalize it well. Generalizing and then insulting him for having the right idea with the wrong words is juvenile.
I would suggesting ponying up the extra dollars for the correct filter. Blowing it out is a could solution to keeping it running a longer time.
No, as Greenman said, air filters don't create back pressure. Who knows if he knew that or not, but that's not what he said. Nor is what he (and you) said about blowing out the filter correct. Read this:

And I don't see how making a filter from an AC return filter would obstruct flow more than the OEM filter.
Nor what he said about me being a cheap ass and risking damaging something expensive correct. If there was a chance for damage, I wouldn't do it. Although, it shouldn't be any more risky than a K&N filter that he's probably used/using. And, odd calling someone on AT a cheap ass, considering a big draw to AT is (or used to be) the hot deals forums. So I like saving money, like they do. So if I'm a cheap ass, they (and possibly he) are too. So I still believe what I said about him not knowing was true, which could easily be said not meaning to insult or be juvenile. So, sorry about the Mustang comment. Just often typical.
I used the wrong term guys. I realize that back pressure is exhaust related, I simply used the wrong term in a hurry. If you do not have the proper intake restriction on most small engines they simply will not run properly as they are not calibrated to do so. Try to run one without an air filter, most will not run. These are not cars.
