High 80% efficient (pink) filter. Our most efficient filter; best used for hard to capture particles like soapstone and eggshell. Also good for maximum efficiency when a single stage is desirable. Because of the fine weave of this filter it is not as easily cleaned as the others and will require more frequent replacement. For best results we recommend using it as a second stage with a standard filter in front.
About Razaire™ filters. There are 4 different filters available for the Razaire™ Z530. While they work fine as single stage filters, they are best used in pairs (stacked). Adding an extra filter stage increases both the performance and the life of the filter, with little to no discernible drop in suction. All filters are approximately 9.75" x 10.5" x 2".
