The Ultraviolet home air sanitizer that fights indoor air pollution and purifies the air in your entire home 24/7.
The UV Light Purifier uses powerful ultraviolet light to help reduce and kill microbials, bacteria, viruses, and other airborne invaders. The use of the ultraviolet light for air purification has been proven effective in hospitals, schools, daycare centers, restaurants, and hotels. It’s even recommended by doctors!
We spend up to 90 percent of our time indoors and according to the Environmental Protection Agency, the air inside our homes is up to 100 times more polluted than outdoor air. Microorganisms can collect to levels that pose health and comfort problems. This problem can be especially serious in energy efficient homes built in the last twenty years. These homes may not allow enough air changes, keeping contaminated air in and fresh air out.
Ultraviolet light purification has been proven effective in hospitals, schools, daycare centers, restaurants and hotels. Ultraviolet radiation is effective in deactivating bacteria, viruses and other pathogens. The germicidal effects of UV light cause photochemical damage to DNA and RNA within microorganisms.
UVC Light is mounted inside the home’s heating and cooling ductwork. The unit mounts with a twist and lock for ease of changing the bulb. Air-Care UVC Light will plug into any standard 120V outlet.
The best location for UVC Silent Light is over the A/C coil. This will treat the indoor air while simultaneously keeping the coil clean. The moisture on the coil and in the drain pan is a prime breeding ground for bacteria, spores, viruses and other contaminants. If there is no A/C system or the location is not accessible, the optional location is in the return air duct, preferably downstream of the filter. For higher square footage applications, installing two air health units, one over the A/C coil in the supply and one in the return, is ideal for its’ cumulative effect.

Biological Inactivation Efficiency of HVAC In-Duct Ultraviolet Light Devices
This document does not constitute nor should be construed as an EPA endorsement of any particular product, service, or technology.
One potential method of terrorism is the intentional introduction of biological warfare agents (BWAs) into the heating, ventilation, and air-conditioning (HVAC) systems of target structures in order to distribute pathogens. Introducing BWAs into an HVAC system could harm many people, so there is an urgent need to identify and test devices that can destroy BWAs as they move through an air handling system. One technology that may meet this need uses ultraviolet (UV) lights deployed inside the building’s air ducts. Short-wave ultraviolet radiation in the “C” band (UVC or UVGI — germicidal irradiation) has been used for many years to inactivate microorganisms. Early research in this area focused on the controlling infectious pathogens in medical facilities. UVC effectively killed Mycobacterium tuberculosis, the causative agent of tuberculosis, and other bacteria including mycoplasma, as well as viruses and fungi.
In testing and evaluating homeland security related technologies, EPA provides unbiased, third-party performance information that can supplement vendor-generated information. This information helps decision makers purchase and apply the tested technologies. EPA conducts its evaluations under rigorous quality assurance protocols to generate high-quality data.
The UVC devices are designed to be mounted inside an HVAC system to inactivate bioaerosols as they migrate through the air handling system. The devices were tested separately in a laboratory-based test duct with advanced aerosol and microbiological generation and measurement equipment. Testing was conducted using three microorganisms, two bacteria (one spore-forming and one vegetative) and one virus, whose structural characteristics and susceptibility to UVC inactivation make them reasonable surrogates for BWAs. Each device was tested three times, once for each test microorganism. Test microorganisms were generated and introduced into the test duct upstream from the installed device. As air flowed through the duct, the bioaerosols passed through the device and were exposed to UVC.
Each device’s ability to destroy the bioaerosols is reported as airborne inactivation efficiency. The greater this percentage, the more effective the device. To determine efficiency, bioaerosol samples were taken from the duct upstream and downstream from the device. These samples were cultured, and the bacterial colony forming units (CFUs) or viral plaque forming units (PFUs) were counted. Device efficiency was then calculated as a percentage from the ratio of the upstream to the downstream counts.
Performance and Results
All UVC devices were ?99 percent efficient at inactivating the vegetative bacteria. Three UVC devices were ?93 percent effective for all three microorganisms. Five devices had ?46 percent efficiency for inactivation of the spore form of the bacteria and two had ?46 percent efficiency in destroying the virus.
a: The systems were run at 0.93 m3/sec (1970 CFM), except the Novatron device was run at 0.14 m3/sec (300 CFM).
b: These values are based on the upper 95% confidence limit for the mean downstream count of the test organism. There were no downstream counts measured.
Other attributes besides airborne inactivation efficiency were assessed. These included dosage measurements, power consumption, single measurement intensity, pressure drop across the device, and air temperature rise through the device.
