There is a new range of PSU devices which are reasonably priced that are able to do the job, and improve the power factor to over 0.97, however if you place the typical noise suppression capacitor that most electrical equipment require to pass the SANAS EMI test, then it drops the power factor to 0.92. For home use this is not an issue as far as SANAS is concerned, but for industry they specify a higher power factor. An interesting issue.
