| A complete "filter pack" for a powered air filter : pre-filter on the left, electrostatic filter
in the center, and a 95% efficiency filter bag on the right.
This photo gives a better idea of the depth of the bag filter, with three separate bags attached
to a single inlet frame.
Any standard air conditioning/furnace disposable filter measuring 12"x24"x1" will suffice for a pre-filter.
A permanent washable metal pre-filter can also be used.
