in WWII to capture radio-
active
particles (Manhattan project).
Advantage:
● Traps dust &
particulate in filter.
● Gas
contaminants get trapped in
charcoal
with additional charcoal filter.
Disadvantage:
● Treats only
small area ~500 sq ft.
● Effectiveness
varies and sometimes is
not
noticeable.
● Very limited in
reducing odors.
● A HEPA filter
is basically a paper filter.
● Requires
constant filter change.
● Very noisy on
high settings.
● Uses high level

● Does not kill
bacteria only traps them.
● May promote
mold and bacteria growth
on the
filter if significant levels are
trapped.

Advantage:
● Collects
particulate on blades.
● Requires no
filters & uses little
power.
● Totally silent
operation.
Disadvantage:
● Treats only

●
Filterless. No filters to fill up landfills.
●
Eliminates odors without toxic chemical
such as air fresheners, plug-ins, or sprays.
●
Kills bacteria naturally (oxidation) without
using anti-bacterial agents (pharmaceutical)
that may promote drug resistant super
