Are Air Purifiers with UV Light Safe?

We are aware of the harmful effects of too much exposure to sunlight. The UV light is the ionizing radiation found in the sunlight that can make it dangerous. This UV light releases electrons from molecules that cause chemical reactions. Since there are plenty of air purifier lamps that uses UV light technology, many people are concerned with how safe it is.

For consumers like us, it is our right to doubt and question the safety of products listed in the market. But first, we must know that UV light is divided into three categories: UVA, UVB, and UVC.

UV light has been used to disinfect water, air, and surfaces for a long time now. Even in ancient times, it is utilized to treat various diseases. Today we will talk about how UV light filter technology can increase the quality of the air you breathe indoors.

How Do UV Light Air Purifiers Work?

This technology is known as UVGI air purifiers or ultraviolet germicidal irradiation. Like other air purifiers, it reduces the air contaminants around your home. The difference is that this technology focuses on inactivating microorganisms and pathogens such as bacteria, germs, and viruses. This means that if your problems are common indoor allergens, chemical fumes, and gas, this kind of air purifier might not be what you are looking for. Ultraviolet air purifiers utilize short-wave UV-C light in order to operate.

This technology is excellent at killing bacterias and viruses which other filter technologies like HEPA and activated carbon are not capable of. This type of air purifier uses a UV lamp. This UV lamp will radiate ultraviolet rays (UV-C light) that will cause damage to the microorganisms and will eventually kill them. This technology gives the filter its best trait in preventing the spread of illnesses and diseases.

The air penetrates through the gadget which goes through the UV lamp. During this process, germicidal irradiation is the chemical reaction that occurs that kills the microorganisms. The result of this process that causes concern is the production of Ozone

Are Air Purifiers With UV Light Safe?

As mentioned earlier, the hazardous side effect that causes concern in UV light filter technology is the production of Ozone. What exactly is an Ozone?

Ozone is a molecule composed of three atoms of oxygen. The two atoms of oxygen form the basic oxygen molecule are the oxygen we breathe that is essential to life and not hazardous. While the third oxygen atom can detach from the ozone molecule, and re-attach to molecules of other substances. When this happens, the chemical composition can be altered. This chemical reaction is the same process that fights the harmful microorganisms and pathogens outside the body. But this can also react with the materials inside our bodies.

When we inhale a significant amount of ozone, it can damage the lungs which can cause chest pain, throat irritation, cough, shortness of breath, and other respiratory issues. It is important to note that only prolonged exposure to ozone is dangerous. When there is only a small amount of it produced, it is still safe.

Thankfully, there are UV light air purifiers that are designed to reduce the excess production of ozone listed in the market today. According to the manufacturers, this is accomplished by layering the bulb with a special substance that stops that UV from generating too much ozone.


It is no doubt that ozone produced by UV light is harmful to your health. If this kind of filter technology is really needed in your space since at the end of the day, it is the best filter technology that kills viruses and bacterias that prevents the spread of airborne diseases. Here are some of the best solutions:

Place your UV light air purifier in a wide and dispersed area with windows. In that way, the amount of ozone produced will not get trapped in that specific place.

Only operate the UV light when no one is in that area. This will lower the risk of inhaling large amounts of ozone that is dangerous for one’s health.
