Electronic Air Cleaners - April 9th 2002
Even in the cleanest homes, air is filled with billions of undesirable particles. Most of these particles are so tiny that they are invisible to the eye.
Outdoor air entering the home carries airborne soil particles, industrial wastes, automobile exhaust, pollen and mold spores.
These are added to dust and other particles generated indoors from dead skin, mattresses, pillows, blankets, carpets, drapes, cooking smoke and grease, pets and if you have smokers tobacco smoke. These particles collect on and in furniture carpets and draperies causing discolouration and staining on walls and ceilings and forming greasy deposits on glass, windows and mirrors. These particles are what cause great discomfort to people sensitive to irritants such as dust, pollen and smoke.
The mechanical filter in most furnaces is capable of removing about 10 percent of these particles if it is kept clean. An electronic air cleaner installed in the ductwork of such a system will remove up to 95% of the pollutants.
With an electronic air cleaner, air passes through a pre-filter, which traps large particles of contaminants. It then enters a powerful electrical field where the remaining particles are positively charged. These pass through another electrical field consisting of negatively charged collecting cells which hold the contaminant particles while the newly cleansed air moves through and out into the home. Now you can breath fresh air.
Maintenance consists of cleaning away the trapped particles. Follow the recommendations of the manufacturer for cleaning.
