Activated charcoal matting

So I'm not sure if I'm putting this in the right thread but here goes...

I've searched the site, and while there is good info on making a homemade carbon filter does anyone know where, in Canada, one can buy activated charcoal matting?

This info would help us a ton. I had read that Wal-Mart sold it (not sure if that included Canada) but a search of the does not result in anything besides shoe inserts. :/

So thanks in advance for any info

I got one at home depot, I dont remember if you guys had them. i got it in the house section and it was for pet odor. I just taped it to the back of a box fan and i really worked.

Awesome tanks for the tip!! We will check out the Depot for sure!!
