Time to quit brewing. It has become clear that we cannot prevent oxygen in our beer. It is simply impossible.
Oh well, I give up.
Might have to find another hobby.

Probably a good idea.

I do ythe best that i can. RedOx reactions will eventually  oxidize the beer, so drink it don’t save it.

It's a freaking hobby.  Do what you can and what you want to, then don't worry about it.

I'm not sure where this went off the rails, but I think good points have been made that are being lost.

Filtering can be a PITA.  If you don't mind doing it, go ahead and continue doing it. Will you get different results than fining/lagering?  Yes, likely.  Some people like those results, some don't.

Avoiding cold side oxygen is always good.  You're never going to be perfect, but try for the best you can.  Is it harder to purge a filter membrane than an empty keg? In my opinion, yes, just like it's harder to clean a plate chiller than a counterflow chiller.  But if you like the results, go for it.

Although CO2 purity has been mentioned, it's important to note that force carbonating is much more likely to oxidize your beer than purging/serving with bottled CO2 because of Henry's law and the partial pressure of gasses.  Bryan had posted these articles from Hach a while ago on his blog, and I thought they were very illuminating:

The second article I find fascinating. I’m going to assume that the way most homebrewers carbonate would be considered “injection” vs “sparging” as referred to in the article. Sparging would require venting of the headspace during carbonation through a stone to scrub the oxygen?

For many years I noticed a rapid change in the hop character of my beers shortly after kegging. I’ve since moved to spunding everything I keg and I feel that the improvement in freshness and stability of subtle hop and malt flavors/aromas is undeniable. My previous method of force carbonating was top pressure, set and forget, thus allowing any oxygen in the bottled CO2 to dissolve into the beer via head pressure and time?

I find this article interesting. Especially the part about TPO oxygen variance with the mobile canner:

Just transferred 20 gallons of 5D into kegs. At least 10 gallons will be filtered. Maybe all 20 gallons.

Might start a new thread to post the results.

you share with family/friends? 20 gallons is a lot of beer

We have donated a number of kegs to friends. They are always happy to help out with consumption.

In fact, we have given away lot's of beer. Kegs, growlers, 16 ounce bottles, etc. One of the neighbors is painting a special picture for me, of one of my beers in a Pilsner glass. Can't wait to see it!
