In many cases, these devices are actually marketed as being especially effective and beneficial to those people who suffer from allergies or asthma.
Today there are a number of different types of air purifiers a person can use both at home and in the work place.
In addition, there are even car air purifiers available today as well.
However, not only do these devices remove contaminants from the air they are both cost effective and good on the environment.
This is because they only require a small amount of electrical power to run them compared to other devices such as air conditioning and heating units.
The different processes, which are often used inside air purifiers, are able to remove different types of contaminants from the air surrounding us and which we breathe.
Below we take a look at what these processes are.
1.
Filter Based - These trap airborne particles dependent upon their size.
The most effective types of filters to be found in these devices today are those known as HEPA Filters.
On average, one of these filters can remove 99.
97% that are no bigger than 0.
3 micrometers in size.

2.
Activated Carbon - This is an extremely porous material, which is able to absorb chemicals that can rather volatile.
However, it does not have the capabilities to remove much larger particles from the air.
This will in many cases used in conjunction with other processes that have been included with an air purifier especially those that have the HEPA filter in them.
3.
Photocatalytic Oxidation - Also known as PCO uses short wave UVC (ultraviolet light).
This process is more commonly used to help sterilize the air and is able to kill around 99.
99% of all bacteria and viruses that are carried in the air today.
However, this is not actually a filtering process because it does not trap or remove any particles that are in the air.
Use this process with either the one mentioned above or below and you will have a filter less air purifier.
4.
Ionizers - This particular process to remove particles and contaminants from the air uses a charged needles or an electrical surface to produce ions that have been electrically charged.
Once the ions have been charged they attach themselves to the particles in the air and will then be electro statically attracted to a collector plate, which has also been charged.
There are two types of ionizer's now available one, which is fanless, and the other, which has a fan.
The advantage of the fanless versions of these air purifiers is that they make no noise and they do not need a lot of power to run them.
Whilst the fan ones are able to clean and then distribute this fresh air much more quickly.
It is therefore important before you actually make your purchase you compare air purifiers to see which one best suits your requirements.
There are plenty of sites that have air purifier recommendations, which may provide you with the right kind of information to help you select the right device for you.
