If so, this video is for you.
We’ll explain exactly how these machines
work to clean indoor air and what you can
expect out of them.
So, keep watching.
How does an air purifier work?
That’s the question we’re covering today.
The truth is, there are actually four different
ways air purifiers can clean indoor air and
each device may use one or more of those methods.
Those ways include:
A HEPA filter
An Activated Carbon Filter
and an Ultra Violet light
Air purifiers that use a HEPA filter work
by using an internal fan to suck air into
the machine and pass it through the filter.
As air goes through the HEPA filter, airborne
pollutants get trapped inside the dense material,
while clean air flows out the other side for
you to breathe.
The great thing about HEPA filters are that
they can capture fine pollutants down to 0.3
microns in size which includes things like
dust, allergens, mold spores, visible smoke,
and some bacteria.
Air purifiers that use an Activated Carbon
filter also use an internal fan to pull air
through the filter to trap contaminants.
The material, however, is completely different
than a HEPA filter.
Activated Carbon is a specially treated medium
that’s very porous, which allows it to adsorb
certain types of impurities from the air.
Activated Carbon filters are specifically
designed to adsorb odors, vapors and gases
from things like smoke, cooking, chemicals,
paints, and other volatile organic compounds.
An Ionizer is another method for cleaning
indoor air but it doesn’t use any filters
The way this type of air purification works
is by emitting negatively charged ions into
the air that latch onto pollutants.
This bond causes the particles to become too
heavy to remain in the air and those clusters
fall onto the ground and other surrounding
Ionizers are great for removing a variety
of airborne pollutants such as dust, allergens,
smoke particles, and mold spores, but keep
in mind that these contaminants still exist
inside a room until you vacuum them up or
wipe them off the surfaces.
The last air cleaning technology you’ll
find in an air purifier is an Ultra Violet
This feature uses short-wave ultra violet
light to inactivate airborne pathogens and
As air passes by an ultra violet light, it
disinfects the air by means of germicidal
Ultra violet lights are the only kind of air
purification technology that can kill airborne
bacteria and viruses inside your home.
Well, that about covers it!
