HEPA means
High Efficiency Particle Arrestance. Nowadays, you can find HPA vacuums
just about anywhere. Most of these are not actually HEPA. Many are junk.
There are no consumer protection laws regarding what can be labelled a
HEPA vacuum, so here are some ways you can find a good one.
1.
Look for one with the filter AFTER the motor. The filter should be the
last thing that air goes through before exiting the vacuum.
2.
Check for gaskets that prevent air from bypassing the filter. This means
that dirt will enter the air in your home and may be sent through the
motor of your vacuum.
Indoor air quality researchers tell us that
there are several brands that have been found to be truly HEPA vacuums.
These include Miele, SEBO and Simplicity (some models).
