Standard 30% efficient (green) replacement filter.
Best choice 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!
There are 4 different filters available for the Razaire 530.
While they work fine as single stage filters, they are best used in pairs (stacked).
Adding an extra filter,
or stage, increases both the performance and the life of the filter,
with little to no discernable drop in suction.
All filters are approximately 9.75"x10.5"x2".
