I think BP was referring to the 30-micron bag DC's as dust blowers.
Although he did say air cleaners take hours to work. Here (source: http://billpentz.com/woodworking/cyc...conversion.cfm):
Many wrongly think all you really need to protect yourself from fine wood dust is a good mask. A good mask only protects you while working. Few leave their masks on long enough. Using an air cleaner or even a modest sized exhaust fan takes about six hours to clean your shop air amply to take off that mask.
IMHO, the Dylos meters exploded a bunch of myths. The particle counters have done a great job exposing a lot of what was once thought to be gospel as little more than marketing hype.
