Qualtex H Level HEPA Post Motor Pre Motor Filter K&hellip by Dyson
5.0 out of 5 stars great product, 10 Aug 2013
these products have revived my hoover, the pre motor filter was a one for one replacement (has cured the occassional pressure popping-lifting of the filter). The post motor allows me to cycle the filter for cleaning and drying without loosing hoover use whilst drying.
