What is the difference between UV Air Purifiers and air filtration?

Both products are effective at removing harmful elements from the air, but UV Air Purifiers focus on removing airborne germs, bacteria and mold while filtration focuses on removing harmful particulates that become airborne.   
 
 

What maintenance does a UV Air Purifier require?

Your UV Air Purifier requires little maintenance. Simply replace the bulb once per year, or once every two years depending on the model.
 
 

What does the CDC say about UV Light Treatment?  

The CDC currently recommends UV lights to reduce transmission of tuberculosis in hospitals. Together the National Institute for Occupational Safety & Health (NIOSH), the Department of Health & Human Services (DHHS) and the CDC wrote a manual for effective UV light installation; recommending UVGI (Ultra Violet Germicidal Irradiation) light technology to kill or inactivate airborne TB bacteria.
 
 
 

Do UV Air Purifiers produce increased ozone?

EPA: According to two studies, operating UV lamps installed in HVAC systems to irradiate the surfaces of air-handling units does not result in increased concentrations of ozone.
 
 
 

Is UV Light harmful? 

UV light can be harmful just as the sun's UV light can be when someone is exposed for too long a time. One should neither look at or touch a UV light bulb while it is on for any length of time. Fortunately, when the UV light system is installed in your HVAC system, there is no direct or harmful exposure to you or your family. Remember to power off your purifier before replacing the lamps and do not look directly at a lamp that is powered on.
 
 

What is it about the PCO2450 VectorFlo® UV Light that makes it especially effective?

The VectorFlo® PCO2450 (Photocatalytic Oxidation) Air Purifier features the patented VectorFlo® semiconductor designed to deliver a high performance kill rate unmatched by other ultraviolet air treatment brands. The VectorFlo® creates a low pressure area around the high output 50 watt UVC lamp establishing a venturi effect. The venturi significantly increases the time exposure of airborne microorganisms in a bath of sterilizing germicidal ultraviolet light. The treated unrestricted air (.02 inches W.C.) is then accelerated beyond the VectorFlo® semiconductor and introduced into the main airflow for maximum purification.
 
From a Penn State University Study:
 
Several attributes of PCO make it a strong candidate for indoor air quality (IAQ) applications. Pollutants, particularly VOCs, are preferentially adsorbed on the surface and oxidized to (primarily) carbon dioxide (CO2). Thus, rather than simply changing the phase and concentrating the contaminant, the absolute toxicity of the treated air stream is reduced, allowing the photocatalytic reactor to operate as a self-cleaning filter relative to organic material on the catalyst surface.
 
Photocatalytic reactors may be integrated into new and existing heating, ventilation, and air conditioning (HVAC) systems due to their modular design, room temperature operation, and negligible pressure drop. PCO reactors also feature low power consumption, potentially long service life, and low maintenance requirements. These attributes contribute to the potential of PCO technology to be an effective process for removing and destroying low level pollutants in indoor air, including bacteria, viruses and fungi.
 
 
 

Why would I want to install a UV light?

UV lights significantly reduce the amount of microbials in ductwork and other airspace in your home. UV lights have the ability to kill viruses, germs and bacteria throughout the home. The 1903 Nobel Prize for Medicine was awarded to Niels Finsen for his use of UV against lupus vulgaris, tuberculosis of the skin. Using UV lights to treat water dates back to 1916 in the USA. Today UV light is used to treat drinking water, waste water and indoor air.
