so same buddy gave me a used filter that someone he knew was using.. but the filter has nothing in it no rating or size brand nothing. there's no way I can figure out the cfm rating or brand?
so I'm assuming it's like an 700 to 1000 cfm filter.. my fans are only 452 cfm.. would they work.. but before I hook it up in my tent I noticed the filter is a little damaged.. the bottom lid thing is kind of loose and it's seems to leave this charcoal like powder everywhere.. that's gonna cause problems in my tent, no?
