Does Uv Light Kill Fungus – Quick Answer 2021


UV light is obtained from several sources at large. The human body uses UV light to produce Vitamin D that is essential in the body for healthy growth. This is why most physicians recommend people to get out and bask in the morning sunlight to acquire these nutrients.

Even though we gain a lot from the UV light, too much exposure is also dangerous. Excessive exposure to too much UV light can make an individual suffer from skin burns. Extreme exposures can lead to the development of cancer in other people. Even though this is the case, this type of light has many beneficial applications. For instance, it is used to detect different biological materials. But then, does UV light kill fungus?

What is UV Light?

It is a form of electromagnetic radiation we cannot see with our naked eyes. There are three categories of UV light. The UVC stands as a powerful option to kill the fungus. This type of UV light is characterized by short wavelengths, making it powerful and effective.

What is UV Light

The UV light is used in homes and industries for different purposes. It can disinfect water, detect various biological materials, and get rid of the fungus. Compared to regular light, UV light has a high frequency. This makes them capable of penetrating through the skin and can be used in many applications.

Does UV Light Kill Fungus?

Does UV light kill fungus? Correct usage of UV light guarantees the killing off fungus and other forms of pathogens at large. UV light can be placed at any point in the house for various applications. Even though this form of light is used to kill fungus, its primary applications include;

Does UV Light Kill Fungus

  • Decontaminating microbial present in the air
  • Water purification
  • Used for medical purposes.

UV light is germicidal when used in homes and industries in short-wavelength frequencies. This means that UV light can destroy any form of germs, including the fungus.

Scientists have proved that UV light is highly effective in killing fungus. The environment where this form of light is used is blanketed entirely to ensure that the entire area is disinfected. While there are other methods to kill fungus, they are time-consuming and not much effective as such. Using a UV lamp, in this case, can kill the fungus within the shortest period that other methods can’t take.

However, the overall effectiveness of UV light to kill fungus greatly depends on two factors. This is how long the fungus is exposed to the UV light and its intensity at large. High intensive UV light is more effective and kills fungus faster compared to less intensive UV light.

UV lights produce powerful electromagnetic radiations that are capable of penetrating through an organism to disinfect it. When the UV light is placed in a lamp, it gets out in short wavelengths capable of killing the fungus cells.

Besides, cells that remain are made unable to get through the reproduction cycle, and they later die. Since fungus spreads rapidly, UV light is a key player at preventing any possible spread that might happen further.

Killing fungus using other methods can be ineffective. A missed cell can reproduce and make a widespread that can be difficult to control. The UV light ensures all cells are killed on the entire surface in a short period. But then how does UV light kill fungus?

To kill any form of fungus, you will first get a UVC lamp. The type and size of the lamp you will get will depend on the range of your needs. Next, you will determine the areas of the body or anywhere that is infested by the fungus. Ensure you kill everything so that they don’t spread further.

Once you know where the fungus has infested, you will station your lamp about two inches from it. When doing this exercise, ensure you switched off light-emitting devices in the house. You should also close all the doors and windows to ensure no form of light penetrates in. You will allow some time to ensure all fungus is eliminated.

Caution: Always ensure you don’t look at the UV light directly once you turn it on. It can damage your eyesight. However, there are special UV glasses you can get to protect your eyes from these light rays. Avoid the standard glasses and get maximum protection from the special UV glasses. Besides this, you should ensure you wear protective gloves when handling UV bulbs, preventing the bulb from damaging the skin.

How Long Does It Take for UV Light to Kill Fungus?

The wavelength of UVC light ranges between 200 and 400 nm. The range is excellent, making it highly effective for purification purposes. This UV light kills all kinds of germs as well as viruses alike. They do this by destroying the molecular bonds between the DNA of these agents. Moreover, the UVC is capable of killing germs that have turned out resistant to antibiotics at large. Here comes a question, how long will it take to kill fungus?


There is no specified period that it takes to get rid of the entire fungus as such. Several factors determine when everything shall be done with. This includes how far you place the UVC lamp to the fungus and its intensity. But then, the typical time to eliminate all fungus is about two hours. UVC is a dynamic form of light capable of killing almost all fungus in the shortest time.


Does UV Light Kill Fungus? The UV light is a dynamic form of light that kills fungus and other forms of bacteria at large. You can use different methods to kill fungus, but they are not as effective as when using UV light. Make use of UV light to eliminate all fungus in the shortest period.
