Considering the amount of irritants that are present in the air 
today, those who suffer from allergies and other breathing disorders are
 challenged to find effective ways to clean the air that they breathe 
within their home environment.
Not
 so many years ago, this simply meant making sure that the house was 
dusted regularly and that pets were bathed and brushed - outdoors - as 
often as possible, in order to cut down on the most common allergy 
inducing factors.  Today, there's far more at stake, when we consider 
the types of contaminants that are present in our environment as a 
result of pollution.  Bigger challenges, then, require better tools for 
providing a solution - enter, the air purifier.
The cleaning of 
the air within your home can be accomplished in a variety of different 
ways.  A simple, straightforward air cleaner is designed to reduce the 
dust build-up within the home, offering the benefits of cleaner air and 
less need to perform common household chores, such as dusting.  These 
are electronic in nature and use a basic filtering system that's 
designed to draw in, clean and re-circulate the air.
Air purifiers
 are a bit more complex, in that they are specifically designed to 
eliminate pollutants such as pollen and other airborne irritants, in 
addition to the dust that the air cleaner removes from the environment.
These
 purifiers are available in a number of sizes, including the portable 
version.  In this case, the air is drawn to the bottom of the cleaner 
and is then pushed upward through an aluminum mesh filter.  This is 
where the pollutants are trapped before the air is moved on to the next 
phase of the process.
An electronic cleaning cell (two-stage) is 
the next stop for the airflow, which ionizes dust particles that are 
invisible to the naked eye and cleans them from the air.  From there, 
the air is diverted to an activated charcoal filter which deodorizes any
 odors that may remain before the air is re-circulated.
An 
electronic air purifier should be placed in an area where the highest 
amount of family traffic takes place, though it can be installed in any 
room of the home.  Complete with a two-speed fan that can typically 
clean an area of up to 300 cubic feet when on the highest setting, this 
type of air purifier would be ideal for a room that measured 20' x 30'.
As
 economical as it is useful, an electronic air purifier doesn't require 
any special wiring, and uses less electricity than that of a 100-watt 
light bulb.
The electric air cleaner is utilized by placing it in 
the central duct system, and cleans the air through the process of 
electrostatic precipitation.  Basically, this just means that when the 
furnace blows smoke and other contaminants into the air, they are forced
 into a filter, then a charging station that provides charges from 
tungsten wires.
From there, any remaining particles are forced 
into a collection area, where they're trapped and washed away by the 
cleaning process.  Charcoal filters are in position to eliminate any 
leftover odors from the air, which is then forced out into the home for 
re-circulation.
Depending upon the design of your home, your 
economic constraints and the level of allergies that your family members
 possess, there's a system that will work for you.  Once the air in your
 home is properly cleaned and purified, you'll all be breathing much 
easier.
