|The DC100 HEPA|
The only problem with this unit is that the extra filters reduce the effective CFM of the collector, so it is not recommended for the largest of cabinets. For these cabinets, you should consider the DC 300 multi-bag dust collector.
This is the DC100 HEPA dust collector with 3 stage filtration. It filters dust particles to HEPA standards. Not only is it a better filtration system, it will save your dust collector motors from burning out as well. This fact alone could pay for the small extra cost within a year.
