ok so this hurts to read so I gave up a few posts ago and will say this rather than turn the fan around because it is blowing in the right direction put the filter on the other side you will need to go out and buy an adapter from a hardware store to do so that's the end of it there go buy the proper adapter and some ducting while you are there. put the filter in the tent connect t o the ducting to the adapter to the fan that's all folks. people have been very patient with you I am tempted to go uncle ben on your ass
