This very fine1 micron grade is only for beer that has fallen very clear, and fining with Instant Isinglass is recommended before using to prevent clogging the filter halfway through a 5 gallon batch. Recommended for experienced filter users. These 8.75" diameter pads fit our Q73 Plate Filter. These are disposable - you will need two pads per 5 gallon batch of beer. Made by Gusmer in the USA.

Q: is this also known as super steril af5? I had some older pads with that label.
A: No, these are made by Gusmer
These work great for cleaning up beer if you want it very clear. No problems.

These work excellent to filter my finished wine before bottling.
