The Midwest filter system has been reconfigured to make filtration easier and less expensive. In order to filter beer or wine you will need to have a Cornelius keg system with a minimum of 2 kegs. Un-carbonated product from one tank is pushed with CO2 through the filter into the sanitized empty tank. In order to polish your beer and remove yeast you will need to do this in a two stage process, which means with 2 kegs you will have to clean and sanitize the originating keg before sending the beer back through the fine filter.
The first filter you will use is a 5 micron sized filter to remove large particulate (hops and proteins) that if left for the fine filters would clog them before you finish. Once your beer passes through the 5 micron filter then it is up to you how fine you want your product filtered. The fine filters consist of a 1.0 micron and a 0.65 micron filter. The 1.0 micron filter should filter out 80-90% of the yeast in solution while the 0.65 - 0.5 sterile filter will filter out 100% of the yeast.
Absolute vs. Nominal filters
Nominal filters refer to the fact that the micron size is loosely rated, so it is at or around the listed size. These are lower cost filters that will work just fine, they are just not as precise as the absolute filters. Absolute filters give you absolute control over the level of filtration your beers go through, they are rated and precise to the degree they are listed, and therefore they are more expensive. For everyday brewing, nominal disposable filters will do the trick. But if you are competitive and looking for a winning edge, a professional precise filtration is what you will want.
These filters are constructed of FDA approved polypropylene spun fiber. The mid-grade and pro-grade filters can be sanitized with bleach at a 0.5% concentration for 15-30 minutes then rinsed thoroughly, provided they are cleaned properly with a back flush with water after each use. The pro-grade filters are auto-clavable for repeated use or in home use, 10-30 minutes in a pressure cooker will sanitize. The manufacturer recommends 10 hours of total sanitizing in the filters lifetime, so with proper use, cleaning and storage the pro-grade filters will be your better investment.
