The short answer to your question is: 0.45 micron nominal filter pads are the industry standard for “sterile” filtration. These pads prevent all yeast and bacteria from getting through. So, if you want to be as certain as possible, it’s best to filter with a 0.45 micron nominal pad. Many winemakers will pass their wine through a 0.45 µm filter and claim that it is a sterile filtration.

#3 0.5 micron nominal filter pads are used for sterile filtration. They are very tight pads that remove very small particulate in your wine, including most yeast and Buy Wine Filters ideal way to get that wine clear from The Home Brew Shop your homebrew supplier Click to view the Hambleton Bard MK4 Filter Pads, Sterile. This is the finest (.4-.6 microns, AF5) super sterile filter pad for the plate filter.

2.Turbidity is not a good indicator of filterability. 3.Speed (high flow rate) is not your friend! 4.High pressure (Differential) is not your friend! 5.Depth filters are the work horse (take out bulk solids to protect the sterile membrane). Sterile filtration--tight enough to catch the smallest bacteria normally found in wine--is defined as a porosity of .45 micron.
This includes cost-effective pre-filtration, whereby contaminants are removed by lower cost filters to protect and increase the life span of final filters. Applying Pall's technologies and expertise in wine filtration to your process will remove risks and ensure peace of mind by enabling more rigorous process control. As you can see from the diagram below, Pall Corporation provides solutions in many aspects of the winemaking process with both traditional and modern wine filtering system solutions that preserve quality and maintain the lowest
Nominal filtration (sometimes called depth filtration) will remove 99.9% of bacteria and yeast cells. Only absolute (aka sterile membrane) filtration will keep the wine 100% free of bacteria and yeast cells.

The finest surface filtration, microfiltration, can sterilize the wine by trapping all yeast and, optionally, bacteria, and so is often done immediately prior to The relationship between sterile filtration and winemaking practice raises a terminology issue.
Trusted as the “gold standard” by generations of winemakers, MilliporeSigma products for clarification, pre-sterile, and sterile filtration will ensure microbial stability while maintaining quality, clarity, flavor, and aroma.

Wines not filtered tight enough for the bottling line can result in extra costs for you, as pre-sterile cartridges will block if the filterability and turbidity levels of your wines are too high. The main questions to ask yourself when considering the best filtration options for your wines are: filtration processes” FDA Guideline on Sterile Drug Products Produced by Aseptic Processing (2004) “The goal of bacterial retention validation studies is to have documented evidence demonstrating that the filtration process will consistently remove a high level of standard bacterium (or isolate)…under process condtions” wine filtration applications since 2000 and does not offer a nylon wine filtration membrane. PES offers significant advantages in terms of colour retention, physical robustness and flow rates compared with nylon. The PES polymer (Figure 2) critically lacks the ability to hydrogen bond, leading to its almost zero colour adsorption.
