Electronic Air Purifiers
Jason Uvios
Although there are various versions of air-purifiers available
today in the market including the HEPA purifier and the UV
air-purifier, but there are only two basic kinds of electronic
air-purifiers. These are the negative ion generators and the
ozone air-purifiers. We will discuss the functioning and
effectiveness of both the varieties in the following section.
Recently, air purifiers are coming with indicator lights that
will notify the user that it is time to change the filter
inside. Previously one always had to keep an eye for that, and
the replacement was based much on guess work. The average
domestic owner doesn't have the expertise to understand if it
is time to replace the filter. With indicator lights, that
shouldn't be a problem anymore.
Ionic Air Purifiers
The basic principle of these air purifiers is based on the
concept of static electricity. What it does is while the air
passes through the purifier it charges the air negatively by
releasing negative ions. Now these negative ions come in
contact with the positive ions present in the air. These would
include the regular pollutants like dust, bacteria, pollen and
chemicals. These remain suspended in the air and we breathe
them in along with the air. Now the negative and positive
charges immediately bond together and fall to the ground. This
is a very simple and basic method, but at the end of the day it
works.
In the more advanced ionic air purifiers there are plates
inside the purifier which are negatively charged. When air
passes through the purifier, the positively charged
particulates are attracted by the plates and are collected. So
the floor remains free of the pollutants.
Ozone Air-Purifiers
The second variety of electronic air purifier is the ozone
air-purifier. However, this variety of air purifier has been
embroiled in much controversy and there is little indication
that the controversy is going to die down anytime soon.
Ozone air purifiers actually release ozone in the air. The
principle is that ozone is composed of three atoms of oxygen of
which the third atom is a free radical and readily reacts with
any organic substance. The manufacturers' theory is that the
free radical reacts with the organic substances in the air,
thus decreasing pollution. And in the process the two other
atoms are now released as oxygen which further cleanses the
air.
The problem is that this free radical can actually react with
the organic substances inside our body and this can be very
harmful for our health and can seriously damage our lungs. So
according to some, ozone air purifiers do us more harm than
they aid us. There is definitely a need to look into the matter
more seriously and there should be more research conducted
before we can come to a conclusion about this variety of
air-purifier.
