Wall mounted return air filter grille that accept 4" Thick Filter

Where can I find an array of different Manufactures that sell a Louvered Wall mounted return air filter grille that accept 4" or thicker pleated filter?
Seems I can find filter grilles for 1" thick filters everywhere, but I would like a 4".
My ruff opening dimensions are 25"w x 18"h however, I can modify. I was thinking a 25" x 16" x 4" Filter if I can find the correct intake grille.
Any help is appreciated.

Thanks in advance

You can look the the local reps from these two companies. They are quite large and can also make custom made products.

AAF - *.*/Products/Replace ... ation.aspx

Camfil - *.camfil.us/Products/

Hope this helps

Be sure you have a big enough return register for the necessary air flow thru the 4" filter. You don't want to choke your air flow with a thick filter that doesn't have enough surface area.
