This 100% works! Materials needed: 2 a/c filters, cheese cloth, bungie cord or elastic bands, fan. Lay the cheese cloth over a single filter panel and spread cannabis evenly, not layered. cover with remaining cheese cloth. Place filter on top of folded cheese cloth with cannabis securely inside. Wrap bungie cords or large elastic bands to hold both panels tightly in place. Lean the two joined panels against a wall. face the fan towards the panels and run for a day of two until cannabis is dry. This works in the MOST humid climates in the world. Meat can be used also to make jerky .. for those pesky munchies later!
