Pure O2 - Is a Sanitary Filter Really Needed?
« on: August 10, 2013, 07:54:13 am »
Just got my O2 system set up and will be using it this weekend for the first time. I have the tank, regulator with flow meter, a length of flexible tubing, and one of those nifty Williams sintered stones on a long metal tube (sintered stone-pop?) Not being 100% sure, I went ahead and purchased an in-line "Sanitary Filter" as well.

For pure O2, do I really need the sanitary filter? I'm pretty sure they are needed for aquarium-pump aeration systems (you never know what's in that air!)

My thinking is that my sintered stone has 0.5 micron holes, and sanitary filters for beer filtration systems run around 0.5 microns, no? meaning anything that might be in my "pure" O2 that could give my chilled wort grief would not make it passed the sintered stone.

Does this sound right, or should I just err on the safe side and use my in-line filter?

I don't use a filter with pure O2. I think that's just to filter out particulates in the air like you said.
