• Final-Stage Microbe Removal: BevBright PP filters catch stuff. BevBright PES filters catch microbes.  
• Specialized 0.45-micron PES membrane ensures a biological barrier against spoilage organisms like yeast, ml bacteria, and Brettanomyces.
• Flavor & Color Preservation: Naturally low protein-binding media prevents the stripping of essential aromas, flavors, and colors from your product.
• Simplified, Chemical-Free Setup: The cartridge requires no pre-wetting or sanitizing, streamlining your SOPs and ensuring immediate, sterile operation.

The BevBright 30" Sterile-Grade has a Polyethersulfone (PES) membrane. Sterile PES membranes have individual .45 holes that do not allow particulates larger than .45 micron to pass.  PES Cartridges provide the ultimate biological barrier and should be used as the final sterile filtration as your beverage is in route to your final packaging. 

A Polyethersulfone layer looks like white film with .45 holes that you cannot see. This film is then supported with a 100+ micron layer of PE on both sides to stability. This outer layer is what you see when you look at a filter. Our PES filters will not hold very much particulate, often called dirt in the filtering world, and will clog very quickly unless your wine is exceptionally clean.

For white wine, a very common usage, it is best to fine and/or filter the wine beforehand as applicable. On bottling day filter first with a pleated BevBright 1 micron filter and then this .45 Sterile PES Filter en route to the bottle.

Common Applications

• Wine: Final filtration for the removal of yeast and bacteria prior to bottling.
• Brewing: Sterile filtration of beer to increase shelf life without heat pasteurization.
• Cider & Spirits: Achieving "brilliant" clarity and biological stability as a last pass filtration in sugar-rich environments.
• Aseptic Packaging: Ensuring sterile water and ingredient streams for sensitive filling lines.
