Ultraviolet Light: Disinfect your home

Ultraviolet light is a spectrum of light from the sun. It has a spectrum ranging from 100 nm to 400 nm.

Ultraviolet light is an excellent way to disinfect your home.

The best way, obviously, is to allow as much sunlight as possible into your home. But given the constraints of modern living, how can we use ultraviolet light to improve our living conditions?

UV light is electromagnetic radiation that falls within a spectrum invisible to the human eye. UV-C light, which occurs between 200 and 280 nm, is the most effective for disinfection.

UV-C disrupts the DNA and RNA of microorganisms, rendering them unable to replicate and causing them to die.

This makes it an efficient method for neutralizing bacteria, viruses, and molds.

There are over nine thousand types of bacteria, over two thousand types of fungii and too many viruses to even count in an average home.

So how can you use it in your home or office?

There are several portable devices you can use. Using the device, you would shine the light on a surface such as a doorknob, table top, remote control, or even your phone.

Shining the light on your air conditioning system can purify the air. Do the same to your water. The light will kill all bacteria and viruses present.

There are challenges.

Direct exposure to UV-C can cause skin burn and damage your eye. Ideally the light should be used when no human being is present.

Devices that emit UV-C light, therefore, typically come with sensors to detect human or animal movement.

It can only disinfect areas where you can shine light. So nooks, corners and areas which are hard to reach remain untouched.

Despite the limitations, ultraviolet light is free of harmful side effects that come with harsh cleaning chemicals or disinfectants.
