I recently posted the parts here.

I back-flush and soak the filters in PBW overnight. Prior to use, I pasteurize the filter in 162F water for 15 minutes. Fill the canister with ~165F water and dunk the filter. Just don't heat it beyond ~170F or it may deform.

Pasteurization will kill any wild yeast and/or bacteria that may be on or inside the filter media. StarSan is great for smooth surfaces but doesn't work well on porous media. Heat is your friend.

Pleated filters have a lot of surface area and are difficult to plug. So, unless you're picking up most of the yeast mass, you'll be fine.

It's a beautiful thing to watch a cold-crashed beer become instantly crystal clear with a 1 micron (absolute) filter.

very nice and thanks. So a 1 micron for absolute and 5 if you just want most of it?

I am guessing with a good crash cool there wouldn't be much anyways.

I filter "bright" beers (e.g., pilsner) with a 1 micron and everything else with a 5 micron. And, yes, I highly recommend you crash cool before filtering to settle most of the yeast and to avoid any foaming.

I, too am without the ability to crash cool right now. Any benefit to the filter for those of us that can't crash cool? Or is that asking too much?

Cheers.

well winter is coming, how cold is it outside?

I have a chest freezer but it is hard to stick a 36" tall keg in it and close the lid, plus I don't want to lift the thing in there since I don't brew anywhere close to where the freezer is.

lamarguy, I was checking out those filters and they say 140*F as max temperature. I guess you haven't seen any warping or anything bad, but I was curious. I would love to find a stainless cartridge so I could autoclave it. It would be worth the extra cost to be able to reuse it indefinitely. Anyone know if they actually make a stainless pleated filter that look like the ones commonly used?

Ya, they're rated for up to 140F under pressure. They may survive an autoclave, since they're primarily made of polypropylene, but I'll let you be the first to test it.

Here are two filters from the same company that will definitely survive an autoclave (100% poly):

Flow-Max HP 2.5" x 9.75" 1 Micron $31.25

Flow-Max HP 2.5" x 9.75" 5 Micron $25.19

I have the Brewers Hardware kit, but am thinking of adding another spunding valve to my arsenal of fermentation tools

I recently moved most of my non-kegerator co2 connections to QD's. I made some patch cords with the various ends ( 1/4 female flare for corny & sankey, a triclamp for system purging, and some others ) , Best money I've spent in a long time !
