My filter setup - Page 3

You could run three of those in a row... 5 micron, 1 micron, .4 micron so you could filter all at once!

Another handy technique is to toss a cup or so of 5 micron DE into the filter housing with your 1 micron cartridge, which would take out the need for the first filter.

My pad filter will allow two levels of filtration and at times I will use 3 micron DE in front of the 1 micron pads, and then finish with 0.5 micron pads..... all in one pass.

I've been filtering for a while. I use a Buon Vino Mini Jet wine filter that comes with a pump. I cold filter from fill tube to fill tube while both kegs are under CO2 pressure from a common source. Works like a charm.

Typically I use the medium filter pads (1um) but have tried the the fine pads (.5 um) as well. Even they won't eliminate severe chill (protein) haze. I can't say I have noticed any change in flavor after filtering. A couple of nice things about the wine filter are cheap filter pads and minimum beer loss in the filter.

Cheers,
Paul

The beer clears up after filtration. I do my filtering when transferring from secondary to dispensing.

One more thing, I also do a cold crash to ~41F for a few days, then transfer.

Hope this helps. Cheers!

I'm interested in whether the 5 micron string filter actually works. I am assembling a similar equipment setup and I was planning to use the string filter. For some reason I had it in my head that the 1 micron charcoal filter would remove flavor components. If that's not the case I'd like to know.

Who knew when I got into this hobby there would be so much chemistry, physics, and math?

My setup is exactly like that with 7, 3, and 1 micron pads.
The beer temperature during filtration is around 34° F.
I use CO2 to push the beer through the filter pads.

I only got one word, WOW! That is an impressive setup.

Cheers!

For those concerned about chill haze, I found this BYO article that explains the defect and how to avoid it.

http://www.byo.com/stories/techniques/article/indices/23-clarity/490-conquer-chill-haze

John Palmer also talks about it in his book,
http://www.howtobrew.com/section1/chapter11-8.html and http://www.howtobrew.com/section1/chapter7-4.html

Finally, I read that sparging water temperature may contribute to the problem. This book is a good source,

Brew Chem 101, The Basics of Homebrewing Chemistry.

Cheers!

Something to remember, especially with the house units, is that with the micron rating, there is nominal and absolute. Most of the filters you buy are nominal. They are only rated to get like 70% or so of the 5/1/.5 micron particles. That may not cut it when filtering beer.
Make sure the beer is cold when filtering and get a 2 or 3 micron absolute filter if you're worried about going down to 1.
