Cold air return grille...very odd size

[eliteconcept]

The cold air return grille for my system is currently comprised of a wood frame and what I would guess is chicken wire or some sort of wire mesh type. I measured the opening and attempted to look at my local home centers for a grille of that size or that would fit. However it is a very odd size I guess....don't remember at the moment the exact size.
Do you guys know of any places online that sell a wide aray of return air grilles?

Thanks

If it's flush to the wall, just get the next size greater, it won't need to be exact. What is the exact size of the hole anyway? Just try to get the greatest free area for the size.

ah i don't remember right now and i'm at work at the moment.
I know I tried one from Lowes....and it was TOO tall and would have gotten in the way of the small closet storage I have just above the opening.
It is configured like this
return air grille on the wall, near the floor.
about 2 inches or so above the return air grille is a small bathroom cloest

thats the problem I ran into...either the grilles were long enough but not tall enough..
or they were too tall and not long enough.

I found some grills from Atlanta Supply, look for them on the web. This company sure has a lot of choices and seem very professional to deal with:

Don't buy the crap they sell at the home improvement places, get a real grille. There's quite a few companies out there which make them. BEFORE ordering one, I'd suggest looking around and seeing what size filters are easily obtained in your area. No use putting in a return that requires a filter size you can't easily get. If you have a filter rack in your furnace, even better, then the return size truly doesn't matter.

wow, they have a wide assortment of sizes. I should be able to find the right size on that website.
I have a filter right at the end of the return air duct before it goes into the furnace. is that what you were speaking of with a rack filter?
would there be any benefit to having 2 filters on the return air?
Thanks so much guys!
