Vent system : I want to know what you guys think of my "plans" to fix up a ventilation system, circulating in/out fresh air. For the screen for the air to go there Im going to be using some charcoal and some filters, like a sandwich : Filter / Charcoal / Filter / Charcoal / Filter / Charcoal / Filter.
Here's a picture of my basement and where my cellar is located and how my ventilation system could be done.
