Standard 30% efficient (green) filter - Razaire Z530

Standard 30% efficient (green) filter. It is best for general wood dust applications or as the first (front) stage when using higher-efficiency filters. It is the easiest to clean and the longest lasting. Superb in pairs! Better performance and longer life can be achieved by "stacking" two ZF20s (#ZH1002 filter frame required).

About Razaire™ filters. There are three 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 the filter's performance and life, with little to no discernible drop in suction. All filters are approximately 9.75" x 10.5" x 2".
