How To: Sterile Filtering while Racking

In these pics I'm racking directly from the primary ferment (better bottle), through a sterile filter, and into the keg.

I did this at about 3 psi in 10 mins. Cider is totally clear, yeast-free, and ready for carbing.

The filter I use is a 2-222 Single-Open End 0.45 micron filter. All plumbing fittings are push-to-connect. Yeast was Nottingham

Is that a filter for a reverse osmosis system? Give me a brand name if you would.

I was under the impression that filtering took some of the taste out of the finished beverage. Have you tried it both ways, to see if that's true?

No, not a RO filter. They require high(er) pressure (about 30 psi), and output waste-water ('brine') in addition to the purified water. Usually you get 1 gal of purified water to 3-5 gallons of waste-water. So RO would be useless and unnecessary for processing a brew.

The filter I'm using is a standard pleated filter, but the configuration and housing are special. Standard housings/configuration are DOE (double open end), which are not 100% leak-proof (i.e. bypass-proof). I'm using a SOE (single open end) filter & housing, which seals via 2 o-rings.

The brand I'm using is Keystone, from McMaster Carr. See this thread for part number etc:

Yes, of course I've tried it both ways. The only taste it removes (in my opinion) is the undesirable taste of suspended yeast. All commercial brews are filtered...

Awesome. Thanks for the info and the tech.

Update to anyone who is interested:

I am still using the original filter I bought from McMaster Carr. I've probably put about 50 gals through it at this point.

Thanks
