The application of our glueball-qqbar filter to the centrally produced KKbarpi system shows that the f1(1285) and f1(1420) have the same behaviour; namely consistent with the f1(1420) being the partner to the f1(1285) in the 3P1 nonet of axial mesons. We determine a flavour singlet-octet mixing angle of approximately 50 degrees for this nonet and highlight that the existence of the supposed f1(1510) needs confirmation.
