Different Types Of Air Purifiers
Jason Uvios
As Americans grow more concerned about the air they breathe the
demand for air purifiers constantly rise. The air purifying
industry has not missed this rising interest and they are now
flooding the market with all sorts of air purifying gadgets.
Each comes with special features and new promises. However if
we go to the basic technology behind all these various models
we will notice that air purifiers are actually of three main
varieties
- Ionic air purifier
- HEPA air purifier and
- Ozone air purifier
There is also a fourth variation - the UV air purifier but
these mostly come in combination with the HEPA air purifier.
Ionic Air Purifier: This variety of air purifier works on a
principle which seems to be inspired from how static
electricity actually draws particle towards itself. In an ionic
air purifier there are charged sheets inside which actually
draws the neutrally charged particulates from the air. Although
this works with bigger particulates, it tends to miss out on a
whole lot of other pollutants present in air. So such purifiers
are very basic and improve the quality of the air partially.
HEPA Air Purifier: these purifiers are much more advanced than
the ionic air purifier. In fact HEPA air purifiers actually
filter the air inside rooms. A HEPA air purifier draws in the
air from the room, filters the particles present in the air and
then releases the cleansed air. A HEPA filter is good enough to
capture particulates as small as 0.3 microns. Such levels of
purification is truly remarkable and even hospitals use HEPA
air purifiers.
However, there are a number of particulates, especially
organisms including a few bacteria, viruses and germs which are
less than 0.3 microns. For such organisms the UV air purifier
has been introduced. They either come with HEPA air purifiers
or they are stand alone machines. The UV air purifier emits UV
light which actually alters the DNA and RNA of the microscopic
organisms so that hey are sterilized and cannot continue to
multiply inside our body.
Ozone Air Purifier: This is perhaps the most controversial of
all air purifier as many think that constant exposure to ozone
at close proximity cannot be good for the human body. However,
there are believers too. This purifier actually releases ozone
in the air. The third oxygen atom of the ozone gets detached
and combines with the particulates while the remaining two are
released as an oxygen molecule in the air. Oxygen works as a
cleaning agent.
