UV Light for Room Disinfection: An Old Idea With a Shining Future


As COVID-19 swept across the globe during the early months of 2020, common disinfectants and sanitizing solutions vanished from local grocery stores and supermarkets. Not long after that, they disappeared from online inventories.

We will continue to adapt to health and safety changes and concerns. Meanwhile, it’s vital to take advantage of long-lasting, reusable sanitizers. UV light isn’t a novel technology, but it may be one of the most potent hygiene tools currently available.

We may not see a decrease in demand for harsh sanitizers (like bleach) anytime soon. As such, a UV light for room disinfection is only beginning to reach new heights of popularity.

If you invest in this tech now, you might be able to stay ahead of the curve. This could help keep yourself, your loved ones, and your home safe from bacterial and viral contaminants.

What Is UV Light?

UV light, or ultraviolet light, is a specific spectrum of light that is often invisible to the human eye. Yet, this type of light can make white-colored objects glow bright and blue.

It can also reveal unseen contaminants, including bodily fluids. For this reason, ultraviolet light is often used by cleaning companies and maid services. A handheld UV light can help anyone locate and erase nasty biological stains.

But while UV light can be exceptionally helpful, it can also cause damage to sensitive objects and tissues, including a person’s skin. That’s because ultraviolet light presents some radiation risks.

If you’ve ever experienced a sunburn, you may already be familiar with the deleterious effects of UV light.

Is UV Light Dangerous?

UV light isn’t particularly dangerous, especially when used correctly. But ultraviolet radiation does pose a significant risk, including an increased risk of developing skin cancer.

Excess exposure to sunlight or tanning bed beams is the primary cause behind UV damage. This type of light can cause premature aging, long-lasting blemishes, and vision problems.

However, the UV light that sanitizers output is not as dangerous as long-term sun exposure. That’s because ultraviolet sanitizers use a low dose of light that can destroy viruses and bacteria without harming humans.

This low-risk form of UV requires more time to be fully effective. But it’s not nearly as hazardous as harsh cleaning chemicals, and UV sanitizers leave zero residues on surfaces. Additionally, UV light can disinfect the air without leaving lingering scents.

Consequently, UV light may be one of the least dangerous sanitizing options available.

How Does UV Light Sanitize?

The same quality that makes UV light dangerous, skin-penetrating radiation also makes it an effective sanitizer. The radiation emitted by ultraviolet light can break apart the DNA strands inside of cells.

When a cell’s DNA is corrupted or rendered unusable, it is no longer able to function or reproduce. In this way, UV light breaks down bacteria and viruses on a cellular level, creating harmless bits of molecules where there was once a threat.

And while chemical cleaners may linger on the surfaces of objects, light can travel across vast distances and penetrate many different types of materials. This makes ultraviolet light an excellent tool for both surface and air sanitation.

Surfaces vs Air

Common disinfectants tend to remove contaminants from the surfaces of objects and items. Chemical sanitizers may also leave a greasy or waxy residue. Harsh cleaning solutions, like bleach, can also discolor furniture, cloth, or plastic.

UV light leaves no residue and can penetrate beyond the surface of an object. Consequently, ultraviolet light is one of the least messy surface sanitizers available. It’s also one of the safest. Still, excess UV light can cause some materials to fade.

UV air sanitizers work in much the same way as UV surface sanitizers. However, they may also have a special air filter and pump to help pull air toward them.

When this air comes into contact with the bright blue light of a UV air sanitizer, all airborne contaminants begin the process of cellular deconstruction. While this process isn’t instant, it could help keep interior air clean and safe.

To get the most out of a UV surface and air sanitizer, you may want to also invest in a high-quality air purifier or dehumidifier. Choosing one with a HEPA filter can help you remove any hovering bacteria or viruses that might be lingering in your home.

UV Light and COVID-19

Because the novel coronavirus COVID-19 is still undergoing rapid research, there are massive gaps in information concerning its transmission ability and long-term surface and air viability.

However, there is plenty of research to support the idea that UV light may kill COVID-19. UV sanitizers have achieved wonderful success in destroying other types of coronaviruses, so it may be an effective alternative to dangerous chemicals.

Naturally, more research and testing is required to confirm this theory. Only time and plenty of experimentation will tell if UV light could be a solution to at-home virus concerns.

Use UV Light for Room Disinfection Now

You might benefit from using a UV light for room disinfection. While strong or excessive UV light can result in injury, most consumer-grade UV sanitizers emit low amounts of radiation.

The result is a people-friendly alternative to corrosive and potentially toxic chemical disinfectants. And while more evidence is needed to confirm the theory that UV light can kill COVID-19, previous research supports the idea.

There’s never been a better time to keep your home’s surfaces and air free of viruses, bacteria, and other dangerous contaminants. By investing in UV sanitizing technologies today, you could benefit for many years to come.
