What is UV?

As we explained in the beginning, UV light air purification is actually a special function which you might consider when buying a purifier for your household.

This is a really unique feature because it’s able to kill dangerous particles and pathogens.

There are different types of UV light and when talking about purifiers it’s good to know that they use UV-C light.

The UV-C light is a powerful radiation which is not dangerous for people, but can effectively eliminate germs, viruses and other microorganisms.

Besides the HEPA and ionic filtering, the UV light technology is the only one that kills contaminants by destroying their core DNA.

Hence, they’re not able to multiply and contaminate the air further.

How do UV air purifiers work?

A UV light is one of the essential features of any good air purifier. They can effectively destroy nucleic acids and disrupt their DNA which leaves the cells incapacitated.

Why is a UV purifier good?

UV purifiers usually work together with other filters to provide best air purifying results.

The first stage of air filtration is the HEPA filter which then exposes the air to the UV light.

After a prolonged exposure of UV light, the DNA of the harmful cells is destroyed and you are left with clean air.

Although, UV light in general can be harmful to our skin, the UV-C type is our friend when it comes to air purification, because it has the ability to destroy cells of harmful organisms.

If the air purifier has another filter, the air will go through it and then be dispersed into the room.

How to test if the UV light bulb is working?

Since the UV light is invisible to the human eye, it’s difficult to know from one glance whether it’s working properly.

What you can do is get a white colored item close to the light to see if the bulb will show a violet shade.

Try this a few times with different object such as a piece of paper or a white sock. If it doesn’t show anything after a few attempts, then it’s probably not working and it should be changed.
