DIY Air Filters

andyfrog | Posted in General Questions on

I’ve been reading up on makeshift air filters, and something I wondered about with the ‘corsi-rosenthal’ boxes is whether or not the cardboard used to seal one end of the cube is airtight.

If it’s not airtight, would it even really matter that much?
