HOW
IT WORKS
The
three scientific principles at work in all ELECTRO-FILTER
Air Cleaners are Impingement, Polarization and
Agglomeration.
#1 Impingement - Impingement is the process that all furnace filters use to trap dust. Simply stated, in order to trap particles the impingement process relies on media being placed in the path of oncoming airborne particulate and striking the particulate as it flows by in an effort to stop it.
Furnace filters using this type of process cover the entire range of efficiencies. The finer and more dense the media used the greater the efficiency.
Impingement type filters always have a built-in compromise between air flow and efficiency.
The greater the flow of air the lower the efficiency except in the case of ELECTRO-FILTER
which also use polarization and agglomeration to trap particulate.
#2 Polarization - The second major scientific principle used in the
ELECTRO-FILTER
is polarization. It is well known that an electrical charge will have an influence on any substance that comes in proximity to the charge.
In the case of ELECTRO-FILTER
Air Cleaners, a strong but harmless (7200
volt dc) charge is established on a screen within the filter media itself. As a direct result of this static charge, the fibers and the airborne particles that come close to them take on an electrostatic charge known as a POLARIZED charge. As a result the polarized airborne particles are drawn together with the fiber media in the same way polarized magnets are drawn together when held close to each other. The attraction is both certain and powerful.
With tens of thousands of charged fiber strands in each filter the efficiency of this polarized process is greatly enhanced. In addition, as each particle attaches itself to the fiber strands it in turn becomes part of the collection process thereby increasing the effectiveness of the filter as it loads.
#3 Agglomeration - Airborne particles enter the
ELECTRO-FILTER
furnace filter and are polarized by the static charge and take on characteristics of millions of tiny magnets.
These particles bond together in clumps and attach around all surfaces of
the charged fibers. The combination of induced electrostatic polarization along with the process of agglomeration makes the
ELECTRO-FILTER
filter completely unique and a highly efficient air filter and in many cases, compares favorably with a HEPA. This is achieved with its very low resistance to air flow. To all this you can order the optional fiber mesh replacement pads with an activated carbon center screen to ensure you have a potent
air filtration device !
