High 80% efficient (pink) filter for the Razaire 530
Nearly 3 times as efficient as the standard ZF20 filter for trapping smaller particles such as very fine eggshell dust or soapstone.
A standard filter ZF20 should be used in front of this filter for longer life
(ZH1002 frame required).
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".
