Here are some common homeowner questions. Click a question below to view the answer.

For odors in general consider our Patriot Carbon. It is specifically designed to fight volatile organic compounds (VOCs) which are the source of most household and chemical odors.

No. All light is a type of radiation but not the dangerous kind. UV light kills germs by giving them an intense “sunburn” and it only affects things it shines on directly. Nothing spreads into the home except clean air.

No. UV-C germicidal irradiation can only kill microbes on surfaces that the light shines on directly (surface kill) or that pass by in the air stream (airborne kill).

These products are intended to be on 24 hours a day. Biological growth doesn't stop when the blower is off, and cycling the UV light on and off would shorten life of the UV lamp.

Running the air system in "fan" mode will cycle air through the home without turning on the AC or heater. Many programmable thermostats have a setting for this as well.

Because UV-C light is dangerous to skin and eyes, lamp replacements are provided by the same HVAC service contractor that installed your Patriot IAQ system.

UV-C light (the frequency used in germicidal UV lights) kills germs by disrupting their DNA which prevents them from reproducing, effectively killing them. In nature this frequency of light is filtered out by the Earth's atmosphere so microbes have no defense against it.

No. Radon is a naturally occurring radioactive gas that can seep into your home from the ground below. It is not the product of any volatile organic compound (VOC) or biological contaminant so UV-C light has no effect on it.

When a UV light system is installed in a central air system the germ killing effect takes place inside the air system and is limited to that area. There is no danger to any living thing in the home except microbes that are carried by the air into the central air system.

No, Patriot UV and Carbon produce no ozone and are perfectly safe.

Never look at the UV light when it is lit. UV-C light can give your eyes a painful "sunburn". Technicians should unplug or disconnect the unit to work on it.

The effect of UV-C light falls off quickly with distance because it is filtered by the atmosphere (air) which is why microorganisms have no defense against it. One should always avoid close direct exposure of skin and eyes, but reflected UV-C light at a distance is not dangerous.
