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.
