3. 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, I’ll explain the core
ones using a shop vac and a HEPA vac.

5. 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.

7. 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.

9. 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.
