The Clean Air Revolution
The huge market for stand-alone air purifiers testifies to the need and desire for clean indoor air. While units for sanitizing the air of an individual room may offer some benefits, to truly remove dust, mold, mildew, bacteria, viruses and volatile organic compounds (VOCs), it is necessary to install effective filters within the home’s heating and cooling system.
The furnace/air conditioner’s filter stands as the first, and most economical, line of defense against air particulates.
Flat surface, disposable filters, designed only to protect the mechanisms of the HVAC unit from dust build-up, have been the standard for decades in residential systems. For purifying the air, they are pretty much useless.
More effective filters now are the re-usable HEPA (high efficiency particulate arrestance) filters and pleated filters. These offer greater surface areas with which to trap particulates down to .3 microns (a human hair is roughly 75 microns in diameter). HEPA filters do well at trapping pollutants; however, they tend to reduce air flow through the system, too, which causes more energy use and possibly a shorter life span for the furnace/air conditioner.
Pleated filters, on the other hand, compete well with HEPA filters while actually increasing air flow. Because the surface of the filter is pleated (formed with peaks and valleys), it contains a much larger area to trap particles while easily permitting air flow rates greater even than standard flat-surface filters.
Pleated and HEPA filters do well in households where no one suffers acutely from allergies or lung conditions.
Active-Field Polarized Air Filters
A much more effective filtration option uses electricity to create polarization of airborne particles like the positive and negative sides of a magnet.
The particles, from the tiniest ultrafine to the largest, become attracted to each other and clump together to form larger units that can’t pass through a filter.
Moreover, the electrified media within the filter also attracts and holds the polarized particles preventing escape back into the circulating air.
These active-field polarized air filters work by way of a dielectric material, or media, placed between two filter screens.
A dielectric material does not efficiently conduct electricity, but it does support an electrostatic field. A conductive filter screen on the intake side of the electrified media creates a more uniform electrostatic field with which to capture the polarized particles.
These highly effective filters can reduce residential indoor particulates by up to ninety percent over a couple of days and can be a lifesaver for those with breathing ailments.
Germicidal UVC Light
Ultraviolet light within a certain frequency range has long been proven to kill or deactivate biological organisms.
With these UVC (shortwave or germicidal ultraviolet) lights installed in strategic locations within the HVAC system (in the return air ducts and in and around the condensing coil), bioactive agents polluting the air become a thing of the past.
The best plan to eradicate air pollutants in your home is to install a combination of polarized air filters and germicidal UVC lights. Together, these two modalities can reduce indoor air contamination by up to ninety-nine percent. Plus, our professional, experienced heating and air conditioning team can install them in your existing system with no alterations to your ductwork.
