Encountering a good bit of people throughout the
year, many of them do not understand the function
and the difference between a regular vacuum and a
true HEPA vacuum.  I wrote a blog on this a while
back, but instead of getting into many of the
technical differences, Ill explain the core ones
using a shop vac and a HEPA vac.

 HEPA stands for High Efficiency Particulate Air.
 A shop vac collects air into the unit which
swirls around the cabin and exhausts out of
muffler.  Locating the muffler is easy because of
the amount of air discharging out of the top rear
of the unit.

A true HEPA vac has all the air only passing
through the filter and it does not have cabin
leaks.  Not having cabin leaks means that the
unit is air tight, and it eliminates the chance
of cross contamination.  Secondly, the air
passing through the filter ensures that the air
is now clean.  And third, the differences between
a shop vac HEPA filter and a real HEPA filter are
endless, including the price.

A general big box store filter costs about thirty
bucks, while a real HEPA filter runs just under
two hundred.  The shop vac will cross contaminate
the work area not only because it has cabin
leaks, but also because the exhaust will blow an
enormous amount of air in the work zone.  So, if
the unit is not marked, HEPA, then the unit is
most likely a regular vacuum which is being posed
as a true HEPA system.
