Ultraviolet rays, or UV for short, are more than that. UV light is also known as nature’s sanitizer; it kills organic matter if the contact is direct. This is the main reason UV light is also used to kill mold in the vents, HVAC system, etc.

You can place ultraviolet light anywhere in the house or other facility. While UV light has many uses, it is beneficial for industries to kill mold.

It is primarily used as a microbial decontaminator that helps in air purification, treating water to make it drinkable or other medical purposes.

UV lights with high intensity are usually more effective at killing mold than less intensive ones.

How Does UV Light Kill Mold?

UV light effectively gets rid of mold due to the power of its electromagnetic radiation. This radiation serves as a disinfectant, penetrating through organic matter to kill them.

The UV light source is fixed in a lamp structure that sends out short wavelengths. These short-beam radiations will destroy most of the mold. All the while also making sure that the remaining cells become useless in terms of multiplying until they die.

Mold spreads like wildfire, and using ultraviolet light is undoubtedly very effective at keeping them from going places and killing at the same time.

If you want to go for manual methods to get rid of mold, that is quite ineffective. The reason behind it is that even if one area, like even a dot of mold, is missed, it will replicate itself at the same rate as before disinfection of the area. Make sure to spread the light (UV) all over evenly to get rid of mold in a short span.
