The filter should have been a 1 micron unit as depicted in the amazon picture, but mine said 20 micron on the insignia. It is to be noted that it said 1 micron in big bold letters, but on the data plate is stated 20 micron. I use these for kegging beer after brewing it, and it flowed very fast, and did not filter much, to indicate that it in fact was a 20 micron, not a 1 micron. It could be a simple mistake, but as mine says both 20 and 1 micron, I am not sure what happened.
I cannot use the filters for the purpose I bought them, which is a shame. I understand that 1 star is really bad, but in this competitive market, seller should check the indication on the units being sold, as to avoid this kind of situation. I will leave it @ 1 star pending future correspondence.
