PICK YOUR OWN
Anyone ever had to do this? Or any ideas ???
Home Depot sells “create your own” filter kits with carbon mesh. I’ve used those and 3M Velcro to keep light out of the air vents on tents. Not sure if it will be applicable for your use because I’m having a hard time imagining your problem, but worth a look!I gotta get baked and stop thinking about it my inner mac guyver will pop up with something at random that and a thru door vent with a filter are my last 2 things to get done before i can fire up the room gonna get the latter here shortly at blowes, 2 layers of ac prefilter may be what i need to block the light from outside
