How UV Lights Improve Indoor Air Quality
You might be surprised to learn how UV lights can transform the air quality in your home or office. By employing short-wavelength ultraviolet radiation, these lights actively neutralize harmful microorganisms, including bacteria and viruses, that lurk in the air you breathe. When integrated into your HVAC system, they continuously purify the air, promoting a healthier environment. But there’s more to consider beyond just how they work. How do you choose the right UV light for your HVAC system and the needs of your particular space?
Keep reading and we will give you the knowledge you need to choose the right UV light.
Understanding UV Light Technology
Before we start figuring out which UV light is right for your application, let’s first take a few minutes to learn how UV lights work. UV light technology harnesses ultraviolet radiation to enhance indoor air quality by effectively neutralizing harmful microorganisms. You might be surprised to learn that this technology is already being used in various settings, from hospitals to homes and food processing facilities.
This means that by incorporating UV lights into your air purification systems, you can significantly reduce airborne pollutants and create healthier indoor air. When you add a UV light to your HVAC system, you won’t just improve the air you breathe; you’ll also create a healthier environment for yourself and your loved ones.
How UV Lights Purify the Air
While many air purification methods focus on filtration, the mechanism of air purification using UV light offers a unique approach. UV lights emit short-wavelength ultraviolet radiation, which effectively disrupts the DNA and RNA of airborne pathogens, including bacteria and viruses.
When these microorganisms are exposed to UV light, their ability to reproduce and cause illness is compromised which reduces or eliminates the negative impact they can have on building occupants.
Benefits of UV Lights
When you incorporate UV lights into your indoor environment, you’ll quickly notice several key benefits that enhance air quality and overall health.
First, UV lights effectively eliminate harmful microorganisms like bacteria and viruses, reducing the risk of illness for you and your family. The power of UV lights was on full display during the Covid-19 pandemic. Buildings which incorporated UV lights into their ventilation systems often times had lower person-to-person transmission rates that buildings without Indoor Air Quality products.
They also help control mold growth, which can trigger allergies and respiratory issues. When UV lights are installed directly above the coil in a home or in the cooling coil cabinet on larger air handlers, they will reduce and even eliminate the presence of microbial growth on the coils.
Additionally, UV lights can neutralize odors, making your space more pleasant. Often times when a UV light needs replacing, building occupants will notice odors that had vanished once the UV light was installed. The reemergence of these odors indicates it’s time to install a new UV bulb.
Installation Options for UV Lights
If you’re considering enhancing your indoor air quality, various installation options for UV lights can fit your needs and preferences. One popular choice is installing UV lights within your HVAC system. This option allows the lights to work continuously, treating air as it circulates through your home.
When installing a UV light in the HVAC system, there are two distinct types of UV lights. There are passive UV lights which treat the air as it passes past the UV bulb and then there are active UV lights which create radicalized hydrogen peroxide molecules which travel through the ducts and into occupied spaces.
Passive UV lights are highly effective at purifying the air stream and also treating the coil in the HVAC unit.
Active UV lights such as the Reme-Halo https://rgf.com/products/food/reme-halo-whole-home-in-duct-air-purifier/ are our preferred option because of the ability to not only purify the air as it passes the UV light, but also because it spreads low levels of hydrogen peroxide molecules throughout the duct system and into the living space where they attack viruses, bacteria, odors, and mold spores. This active approach leads to a far greater impact on the overall indoor health of the building.
If a home or building uses boiler heat and lacks central air conditioning, a standalone UV light is the perfect option. These portable options give you the flexibility to target areas with higher contamination risks. Additionally, some homeowners choose to integrate UV lights with air purifiers for a comprehensive approach.
Whichever method you choose, ensure the installation complies with safety standards and is performed by a qualified professional to maximize effectiveness and minimize risks.
Considerations for Use
After selecting the right installation option for your UV lights, it’s important to consider how to use them effectively. First, decide if your goal is to maintain a clean cooling coil or if you are looking for a total home solution. Once you decide on which approach best meets your needs, research available options and find the best unit for your budget.
A couple things to remember regardless of which approach you take, all units will require annual or bi-annual maintenance. Regularly check the bulbs for functionality and contact your service provider when the bulb no longer works. Most UV lights will last between 1 to 2 years before needing replacement. Lastly, educate everyone in your space about safety precautions, since direct exposure to UV light can be harmful to your vision, they should never be removed while power is connected.
Conclusion
Incorporating UV lights into your indoor environment can drastically improve air quality and overall comfort. By effectively neutralizing harmful microorganisms, these lights help create a healthier living space, reducing the risk of illness and respiratory issues. Whether you’re considering installation in your HVAC system or exploring standalone options, the benefits are clear. Embracing UV light technology is a proactive step toward ensuring you and your loved ones breathe cleaner, safer air every day.
