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

An Ionizer
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

at all.

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!
