UV Germicidal Light

7 Benefits of a UV Germicidal Light

Germicidal lights are simple, effective ways to curb bacterial, yeast and viral growths. These specialized lamps produce an ultraviolet (UV) light that disrupts growth and deactivates existing growths, aiding in the disinfection of surfaces, water and more. Using one in your home can help improve everything from air quality to the health and well-being of you and your family.

Some other reasons to consider integrating a germicidal UV light into your home?

#1. Curbs mold and bacterial growth

Again, the main benefits of a UV germicidal light is to curb mold and bacterial growth. By deactivating bacterial and viral DNA as well as other pathogens, these lights keep them from growing and spreading. In addition, germicidal lights can kill existing germs and bacteria, sanitizing spaces and keeping your home or office clean and healthy.

#2. Reduces colds and flus

By treating the air circulating in your heating and cooling system, UV germicidal lamps can kill mold and destroy airborne viruses and bacteria that, ultimately, lead to colds, flus and other illnesses. This can keep you and your family or staff healthy. Many experts recommend adding in an air purifier to filter even more germs and bacteria from your indoor air.

#3. Lessens unpleasant smells and household

Mold and mildew happen—too much water or dampness gets trapped in air ducts, vents and other enclosed spaces, which can lead to unwanted growths and, from there, not-so-pleasant smells and odors.

In killing mold and mildew spores and build-ups, UV germicidal lamps not only eliminate the problem—and make your air healthier and more breathable—but, also, curb the noticeable smells tied to these growths. It’s a win/win—better, fresher air quality without heavy decontaminants or chemical treatments.

#4. Removes VOCs

Mold and mildew aren’t the only odor causes. Often volatile organic compounds (VOCs)—toxic chemical vapors like toluene and formaldehyde—lead to strong odors and airborne contaminants. UV germicidal lights can quickly neutralize these odors, removing them from circulating air and making air quality better, safer and healthier.

#5. Reduce clogging in condensate drains

Your condensate line is a critical piece of your HVAC system. While this line is responsible for a host of key activities, the most important is its draining excess water and moisture outside of your home.

However, because these drains are constantly exposed to water and moisture, it’s common for algae to grow within the lines—and that can lead to a host of issues, including less than-the-optimal flow and clogging. A germicidal UV light not only curbs algae growth but, also, kills existing algae growth over time, keep drains and lines algae- and clog-free.

#6. Reduces electricity costs

All of these growths—mold, mildew, dust, insects and other buildup—is not only bad from an indoor air quality perspective but, also, from an efficiency perspective. The bigger the buildups, the harder your appliances, lines, pipes and HVAC system have to work to move air through your home. That can, immediately, reduce efficiency and increase electricity costs. In other words, you’ll pay more for not-so-great heating and cooling—not ideal.

#7. Effective, even in humid climates

Unlike many treatment options, UV germicidal lights work well even in our humid Memphis climate. In fact, many light options thrive in our humid conditions, delivering even better results over drier climates. Between the effectiveness in humid weather and the no-chemical approach, it’s clear why so many area households opt for UV germicidal lights—and why TruClean recommends them to our clients every day.

UV Germicidal Light FAQs

Considering integrating an ultraviolet (UV) germicidal light into your home or office? It’s a smart move. From killing germs, bacteria, viruses and mold in tough-to-reach places to improving indoor air quality to maximizing energy efficiency—and lowering your bills—there are countless reasons to consider these powerhouse lights.

Still have questions? Read on for our most common FAQs—or get in touch with TruClean to ask any additional questions and plan your next steps.


Does the UV germicidal light really work?

In a word, YES. Ultraviolet light is germicidal, meaning it deactivates and kills DNA of bacteria, viruses, mold, mildew, algae and other pathogens. This immediately destroys these growths’ ability to multiply, expand and decrease the quality of your indoor air—and make you sick.

Do these lights get hot?

UV germicidal lights produce very little heat—about the same about a fluorescent lamp. As a result, these lights are very safe for home use.

Has UV light technology been tested?

Yes. UV purifiers and germicidal lights have been tested extensively. Today’s lights are designed to produce a set level of ultraviolet—in most cases, about 16,000 microwatt seconds
per square centimeter, though many have higher levels. The microwatts will determine how long it takes to curb germs, bacteria and other growths.

Have indoor airborne contaminants increased?

Given the increases in pollutants, allergens and other bacteria, viruses and contaminants, indoor air quality has been top-of-mind. Now more than ever, it’s important to understand the risks and control—or, ideally, improve—the quality of your indoor air. Without proper cleaning and filtering, indoor air quality can quickly decrease because of the added contaminants circulating. This can lead to illnesses, irritation, headaches, dizziness and fatigue.

Don’t air filters eliminate germs?

Air purifiers remove microorganisms from the air, curbing the spread of bacteria among other harmful contaminants. HEPA filtering systems are even more effective than standard models, filtering even more bacterial particles to keep air clean. This can help destroy viruses in-air—however, for air purifiers to be effective, harmful contaminants need to be in the air. UV
lights, though, can tackle germs, bacteria and viruses on surfaces, in air ducts and more.

What kind of germs are affected by the UV light?

UV light kills and deactivates germs, bacteria and viruses that cause colds, flus and other common illnesses and infections. Quality lights can kill up to 99.9% of most airborne bacteria,
viruses and mold spores.

Where in our home should we place the UV light?

UV germicidal lights are extremely versatile and can be placed virtually anywhere in your home or office. Some common placements include under sinks, in swimming pools and hot tubs, in or adjacent to air ducts and vents and any other spot where you’re concerned about clean air. Many people place lights in ceiling fixtures above a room to help promote clean air circulation.

Do these lights need chemicals to function/work?

Absolutely not—that’s another major benefit of using UV germicidal lights to kill harmful contaminants and pathogens. UV technology is a chemical-free approach to disinfection and decontamination. Not only will you avoid introducing potentially harmful chemicals into your home but, at the same time, you’ll avoid the added cost—and added headache.

UV lights and purifiers are a very simple, very straightforward approach to disinfecting your home or office. There’s nothing you need or need to do besides introducing a light into your
space. From there, the UV light does the trick—it couldn’t be easier, safer or more effective.

Are there any negative side effects to using these lights?

Limit prolonged, direct exposure as you would with any UV light. Too much exposure can lead to temporary skin redness and/or eye irritation.
