Air Quality FAQ: How Does a UV Germicidal Light Work?

Improving indoor air quality can play a vital role in improving your family’s health. From air purifiers and air filters to dehumidifiers, there are a number of things you can install to clean the air within your home. UV germicidal lights can be a huge help with indoor air quality. 

To the uninitiated, UV or ultraviolet light is a type of electromagnetic radiation found naturally in sunlight. It makes up nearly 10% of the total light the sun generates. This light is not visible to the naked eye and can be distributed into three sub-bands: 

  • UV-A: Wavelength range between 315 nm (nanometers) to 400 nm 
  • UV-B: Wavelength range between 280 nm to 315 nm 
  • UV-C Wavelength range between 100 nm to 280 nm 

What does that have to do with air purification, though? Here we highlight how UV germicidal light can be used for disinfection and if you can benefit from a UV air purifier in Orlando, FL.

How Can We Use a UV Germicidal Light for Disinfection? 

UV light having wavelengths less than 290 nm have germicidal properties. The Earth’s ozone layer typically absorbs all ultramagnetic radiation that has a wavelength less than 290 nm. However, if bacteria, viruses, and other microbes were exposed to this light, it could kill them by damaging their genetic material and destroying their ability to reproduce. 

The Centers for Disease Control confirms this and says that UV light is capable of disinfection. The amount of UV light required to kill bacteria or a virus can vary according to the size of the genetic material. So far, there have also been no reports showing that microbes have built up an ability to withstand destruction by UV light.  

A UV germicidal light uses the same principle. It is a method of disinfection that utilizes short-wavelength ultraviolet light for killing or inactivating microbes and pathogens. You can use it to disinfect the air, water, and surfaces. Installing a device with a UV germicidal light can purify the air by killing all pathogens and improve the overall indoor air quality.

There are several methods to use UV germicidal light for improving indoor air quality. One way to do this is to use a UV air purifier. A UV air purifier filters air while simultaneously subjecting it to UV germicidal light to kill organic pollutants such as bacteria and viruses and removes them from your home. The result? You get cleaner air that is free of pathogens and promotes your family’s health. This small addition to your home can make a big difference to indoor air quality and protect a home’s inhabitants breathing in contaminated air.
