I'm using the same large wardrobe box but no fan or filter for me. Just holes up and down the sides for airflow.
I don't know how you guys are getting a slow dry using an exhaust fan. Last harvest I dried in my little veg tent with an 11w duct fan I use as an exhaust and it dried them out too fast in 4 days, even at 45-55rh. I like to shoot for 6 to 7 days minimum before I jar.
Thanks to the OP because this is where I found out about the box years back.
