Filter Sheets - 40 cm x 40 cm (0.8 Micron) 100 Sheets

40cm x 40cm filter pads made for 40x40 plate filters. 0.8 micron pads are for ultra-fine polishing of the wine, or for preparing hard to filter wines to go through a sterile cartridge filter. Please note that all pad filters are rated 'nominal', meaning that about 90-95% of all particulate matter at the micron rating will be filtered out. There will always be a little bit of smaller material that is also filtered out, as well as some larger material that will make it through.

The filters can be sterilized by in-line steam, auto-claving, dry heat, hot water or chemical methods. We choose to run Saniclean (CL27) solution through the pads followed by sterile water or a small amount of wine that is then discarded. After the solution is run through the pads, and the pads have softened, the filter will need to be re-tightened.

Each pad has an entry side and an exit side, distinguishable by their different textures. The entry side is a billowy type texture, frequently called the "rough" side; and the exit side has a crosshatch pattern and is commonly called the "smooth" side.
