In Duct Air Purification Systems with Proven Solutions

Many Health Benefits to In Duct Air Purification System

There are many health benefits to in duct air purification systems, which keep the air we breathe clean, pure and free from germs, pollutants and irritants. Air purification systems are used in AC Units and HVAC duct equipment to provide maximum health benefits to people exposed to air in factories, offices, hospitals, doctor offices, and residential dwellings. Ultraviolet (UV) air purification effectively eliminates dust, mold, mildew and germs and prevents these contaminants from entering the air we breathe.

Breathing clean air is important to all people but is especially vital for the sick or immune compromised, or the very young or elderly, providing added comfort to people with asthma or respiratory conditions. It is also important to prevent the spread of bacteria and viruses, and to maintain a healthy environment, promoting continual health and wellness.

Effectiveness of UVC Air Duct Purification Systems

There are various wavelengths of UV output, and only a very specific wavelength of 253.7, commonly referred to as 254 nanometer (Nm), is effective at killing bacteria and viruses. There is also no damaging ozone release at this optimum output. Some air purification systems may emit a small amount of ozone which might be acceptable in certain applications; this is not desirable in duct air purification systems as it may corrode the cooling system of an AC unit by separating aluminum fins from copper lines in the cooling coil.

Be sure that you know the UVC output of any in duct air purification system, and accept only 254 Nm UV output to achieve desired germicidal and purification results. The experts at LightSources are ready to assist you with proven solutions for any UV air purification system, including in duct air purification.

Proper Installation is Vital for In Duct Air Purification System Effectiveness

UV in duct air purification systems must be mounted near the cooling coil, on the cold air side, or downstream. The output must be targeted toward the cooling coil and the condensation drain pan under the coils to prevent growth of mold spores and algae. If your system is not installed properly it could still allow mold and bacteria growth, contaminating the blower and all air in the entire living space. Mold and algae growth will also clog the coils in your AC unit, causing the motor to overwork and burn out faster than with these contaminants eliminated.

By eliminating these contaminants in your HVAC units and duct work, you not only provide healthy clean air to breathe, you also greatly enhance the performance and prolong the life of your valuable HVAC equipment.

The Advantages of UV Air Purification

There are several advantages to purifying the air we breathe through the air ducts in our living and working space. The health benefits are clear; while extremely effective they are also completely safe. UV air purification systems are maintenance free, providing long lasting effectiveness while prolonging the life of your equipment. Producing healthy air and enhancing the quality of life is the most valuable advantage of all, although installing in duct air purification systems will continue to provide several additional advantages for years to come.

How Does a UV Germ Light Work?

Originally posted at: https://www.light-sources.com/blog/how-does-uv-germ-light-work/

If you’ve heard of a UV germ light and wondered just how effective it really is and how it works, read more to learn how a UV germicidal lamp really works. Ultraviolet (UV) radiation is measured by wavelengths, referred to as nanometers (nm). Ultraviolet light is broken into UVA, UVB and UVC rays, based on how long the wavelengths are.

UVA rays are found between 315nm and 400nm, UVB rays are between 280nm to 315nm, and UVC rays are shorter wavelengths measuring between 200nm to 280nm, with the most effective germicidal action found at precisely 254nm. UV germ lights in the range of 254nm are proven to be highly effective in purification and disinfection applications, eradicating bacteria and viruses in the air, water and even on surfaces. UVC radiation works by instantly altering the DNA of the organisms by penetrating the cells quickly within seconds of exposure. This instant exposure to UVC light renders these living cells completely harmless as they are unable to replicate.

Short wave UVC light is the most effective type of UV radiation to damage cells and is filtered by the atmosphere, never reaching the Earth’s surface. Shorter wave UVC light at 185nm is used in UVC ozone-generating germicidal lamps, which is powerful UV radiation that actually eliminates odors in the air caused by volatile organic compounds (VOCs) such as sulfides, mercaptans, and ammonia. By penetrating the nucleic acid of the cells, they are unable to multiply or reproduce to infectious numbers, leaving them to be considered dead and inactive. UVC light in the short wave of 185nm decompresses oxygen, O², and produces ozone, O³. Ozone is a powerful oxidizer that destroys microorganisms within seconds of exposure.
Many Benefits of UV Germ Light Technology

There are many benefits provided by using UV germ lights instead of other disinfection methods. UVC germicidal lamps comply with strict environmental codes and regulations, as it is completely free of chemicals and environmentally friendly. UV germicidal lamps do not contain corrosive materials or disinfection by-products (DBPs).

Originally posted at: https://www.light-sources.com/blog/uv-disinfection-kills-germs-chlorine-doesnt/

We’ve been hearing a lot about UV disinfection and the many uses for disinfecting air, water, and surfaces, but do you know that UV radiation can eliminate germs that chlorine does not? Ultraviolet (UV) germicidal radiation is a popular method of disinfection in many water and air purification systems, due to its highly effective disinfection properties and the many health and safety benefits. UV disinfection is fast, effective, and completely safe, providing many advantages over other methods of water disinfection such as chlorination.

In addition to the many benefits of UV disinfection systems, UV light has been proven to eradicate an extensive list of harmful pathogens such as viruses, bacteria, and protozoa. One key advantage that UV purification systems offer over chlorine-based disinfection methods is the effectiveness of eliminating protozoa such as Cryptosporidium and Giardia which can be chlorine resistant. UV germicidal disinfection has proven to be highly effective at eradicating these parasites from water supplies to prevent widespread intestinal illnesses.

How Does UV Disinfection Work?

UV disinfection works by short-wave UV light causing a physical reaction to the RNA and DNA of cells in microorganisms which renders them incapable of reproducing and infecting. UV light is invisible to the human eye, falling in between visible light and X-rays on the electromagnetic spectrum. UV light is emitted by the sun, although most is absorbed by the ozone layer in the Earth’s atmosphere.

UV light is measured in wavelengths referred to as nanometers (nm), which is a billionth of a meter. UV emissions in the UVB and UVC range of 200 to 300 nm are considered germicidal, which means they are effective at inactivating microorganisms such as viruses, bacteria, and protozoa. UVC lamps are used in disinfection applications worldwide, providing effective, safe, and environmentally friendly disinfection without the use of chemicals and harmful byproducts.

Effectiveness of UV Disinfection

UV disinfection has been proven to be highly effective with instant disinfection of pathogenic organisms such as those that cause hepatitis, cholera, typhoid, polio, and viral, intestinal parasitic diseases.

Hospital UV Disinfection: Highly Effective with Automatic Solutions

Originally posted at: https://www.light-sources.com/blog/hospital-uv-disinfection-highly-effective-with-automatic-solutions/

Healthcare facilities face serious challenges with mitigating the spread of germs and are seeking enhanced methods of disinfection such as hospital UV disinfection systems. Healthcare-associated infections (HAIs) cause nearly 100,000 deaths in the U.S. annually with approximately 1 in 25 people contracting an infection from their hospital stay. HAIs cause unnecessary deaths and put patients and staff at an increased risk.

The hospital environment plays a critical role in the transmission of pathogens, as many harmful viruses and bacteria can remain on surfaces for weeks, months, and even years. Superbugs which are resistant to antibiotics such as Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococci (VRE) pose additional challenges to keeping patients and hospital staff safe from infection.

Challenges in Disinfecting Hospital Rooms and Surfaces

Many challenges exist in preventing the spread of infection in hospital rooms and surfaces. Disease outbreaks have been traced back to many sources such as thermometers, blood pressure cuffs, sinks, and counters in patient rooms, and computer keyboards. This puts hospital staff at risk of contracting and spreading dangerous pathogens.

Hospital staff are expected to thoroughly clean patient rooms and use disinfectants known to kill pathogens of a previously infected patient. Some chemical disinfectants may require a long exposure time to provide effective disinfection and may not even be applied to all infected surfaces. Cleaning materials themselves such as mops or cleaning cloths may also become a source of transmission, spreading harmful pathogens rather than eliminating them.

Due to these challenges facing the healthcare environment with ineffective chemical treatments and the resistance of certain pathogens, it is imperative to incorporate enhanced disinfection with hospital UV disinfection.

Enhanced Disinfection with Hospital UV Disinfection

UV disinfection in hospitals is becoming an extremely popular method of assuring protection against the spread of harmful diseases, with a high rate of efficacy. According to a study published by Cambridge University, UV disinfection systems reported >99.99% effectiveness in eliminating resistant pathogens such as:

·        Middle Eastern respiratory syndrome coronavirus (MERS-CoV) which had a reported mortality rate of approximately 36%

·        Severe acute respiratory syndrome (SARS)

·        Mouse hepatitis virus, strain A59 (MHV-A59)

UV disinfection systems provide a high rate of efficacy, although they are most effective in hospitals when used in addition to standard cleaning of hard surfaces and should never be considered a substitute for good cleaning practices.

Automatic UV Disinfection Systems for Hospitals

UV disinfection in hospitals is gaining traction due to the high rate of effectiveness and also because of the ability to automate the disinfection process. Many types of hospital UV disinfection systems are available such as:

·        Portable UVC robots and UVC light carts

·        Stationary solutions such as UVC lamps in light fixtures, overhead doors, and doorways

·        UVC lamps in HVAC systems disinfect the air

·        UVC lamps in water systems for clean water supply

With a wide range of UVC disinfection systems available to incorporate into hospitals and healthcare facilities, automating an effective UV disinfection solution is much more attainable than in previous years. Integrating UV disinfection systems with building management systems allows for facility managers to activate UV light disinfection systems on demand or as an automatic cycle in various areas of the hospital.

Automated hospital UV disinfection systems provide an invaluable benefit to protect patients and staff as well as cost-effective operation with no required labor. Activating automated UV disinfection in operating rooms after surgeries and prior to new patient arrivals adds a protective layer to manual cleaning and can reach odd places that may get overlooked during manual cleaning processes.

A study published by the National Institute of Health (NIH) in 2013, concluded that an automated hospital UVC system led to a significant decrease in the total number of colony-forming units (CFUs) of many types of organisms including Vancomycin-Resistant Enterococci (VRE), C. difficile and Acinetobacter.

Hospitals can incorporate automated UV disinfection systems in operating rooms, patient rooms, labs, storage facilities and on equipment surfaces. UVC germicidal lamps offer an enhancement to traditional cleaning methods and are proven to be more effective than cleaning with chemicals alone.

UVC Robot: Autonomous Virus Killer on Wheels

Originally posted at: https://www.light-sources.com/blog/uvc-robot-autonomous-virus-killer-on-wheels/

Ultraviolet radiation in the UVC range is known for killing viruses, bacteria, and harmful pathogens in many applications. You can find UVC germicidal lamps in disinfection systems worldwide used to kill viruses and bacteria in water, in the air, and on surfaces. UVC disinfection lamps are mounted in various disinfection systems, like water treatment plants, air purification systems, and industrial machines.

With advances in technology and robotics, UVC germicidal solutions are available in many forms of automatic UVC robots. These UVC robots can roam indoors and outdoors, killing viruses and bacteria almost instantly. UVC germicidal lamps are proven to kill most infectious microorganisms in seconds and eliminate difficult-to-treat pathogens like Methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE) in minutes.

UVC Robots Beneficial in Many Environments

UVC robots are now popping up in many places such as hospitals, office buildings, shopping malls, libraries, and airports. Outdoor disinfection robots can be found on school campuses, industrial parks, and many other public gathering areas. These disinfection robots can be programmed to spray a disinfectant and also emit powerful UVC radiation at the precise wavelength of 254 nm, proven to have the most germicidal effectiveness.

The benefits of these autonomous robots are clear:

• No labor required – UV disinfection robots can disinfect a large area with no labor required. They can run for 24 hours continually and even head back to their charging station when needed.
• No infectious disease exposure to humans – while the robots are disinfecting an area, human employees such as nurses in hospitals are not exposed the superbugs that may be lingering in the room.
• Effective germ-killing ability – UVC robots are proven to eliminate most viruses and bacteria and even hard-to-treat pathogens which pose serious risks when exposed to humans.
• Safe when used without people in the room – UVC robots are set up to enter hospital rooms or other areas when vacant to avoid UV exposure to humans. They can be controlled remotely and programmed to shut down if movement is detected.

Proven Effectiveness of UVC Radiation in Hospital Rooms

According to a study in Infection Control & Hospital Epidemiology, UVC devices effectively eliminated bacteria on contaminated surfaces both in the line of sight and also behind objects. UVC radiation was 99.9% effective in reducing the counts of vegetative bacteria on surfaces within 15 minutes and was also proven 99.8% effective in reducing superbugs and C. difficile spores within 50 minutes.

UVC robots and UV germicidal devices are only as powerful as the quality of UVC germicidal lamps installed on the systems. Using high-quality UV germicidal lamps is key to achieving maximum germicidal effectiveness.
