OK just been wondering about this. Currently I am using a airpump and 2micron air stone to get the O2 into my beer prior to fermentation. I boil my stainless air stone for about 10 minutes prior to use and sanatize my air lines that will be anywhere between the hepa filter and the air stone, BUT . . . .
What about that hepa filter? Should I be sanatizing that thing as well and if so how?
