Comptech Icebox replacement filter?

[dave_f]

Hi guys, have the above intake and wondering does anyone no where I could get a replacement filter?! Been looking online and cant find anything definite for it. I thought a DC2 one would fit but it doesn't, the DC2 one is slightly bigger.

Here is pics online I've found, I'll get some of my own when I get a chance.

Any help appreciated!
