The filter should be 1 micron as shown on the Amazon picture but my logo says 20 micron. It is noteworthy that 1 micron is indicated in large, bold letters, and 20 microns are indicated on the nameplate. I use them to keg the beer after brewing and it flowed very quickly and was barely filtered indicating it was actually 20 microns and not 1 micron. This could be a simple mistake, but since mine says both 20 and 1 micron I'm not sure what happened. I can't use the filters for the purpose I bought them for which is a shame. I understand that 1 star is very bad but in this competitive market the seller should verify the information on the units they are selling to avoid this situation. I will be leaving this @ 1 star in anticipation of future correspondence.
