I did a DIY mod to put a fan in my mask and it works great, even though it's a 99 cent fan and a $20 walmart mask . But I was wondering whether it should be intake or exhaust. It is blowing the air in to my mask right now, but would performance be increased if I make it blow air out? also would this make the mask cool off more in I make it exhaust the air rather than take it in?
thanks for any help!
