Removing carbon from Penguin filter cartridge
Lenny:
I was looking at the pictures on your blog where you showed how you cut an H on the black plastic back of the cartridge to remove the carbon. Does that mean that you have a flap on the top and the bottom? And after bending the flap back and forth, doesn’t it eventually just break off? I have some new cartridges and also two aged ones in the filter and suppose I should practice this surgery on one of the new ones rather than ruining one that has bacteria in it? Barbara
