Air Filters -vs- Air Purifiers
Most home heating systems are designed to have an air filter (furnace filter). These slide-in filters amount to a whole house air filtration system, but not an air purifier.
They operate by pulling your home’s existing air through a network of air duct returns. The air is then pulled through the furnace filter which, depending on the type of filter, will reduce dander, pet hair, air borne particulates, dust, and other larger particles.
In contrast, an air purifying system, sometimes called an air cleaner system, purifies the air using needle-point bi-polar ionization which creates equal amounts of positive and negative ions. When these ions come in contact with viruses, bacteria, or mold they remove the hydrogen molecules. Once the hydrogen is removed, these pathogens have no source of energy and will die.
Another purification method is by using UV light. In this method, UV lamps are added near the indoor coil of your air conditioning system. The installation of these lights are designed to kill viruses, mold, and bacteria, which can collect in the drain pan.
A buildup of these organisms can reduce air flow, eventually become airborne, and blown throughout your whole home. The addition of the UV lamps increase the efficiency of your hvac system while simultaneously keeping your air fresh and clean.
