UV-C light for air purification, has gained popularity as an effective method for air cleaning.

Based on the UV-C light capability to neutralize harmful microorganisms it is often used as a better technology in most industrial air purifications.

From today’s Know Your Facts we are going to briefly point out the benefits of UV-C light for air purification and how it can help create a healthier environment at your place. Read and enjoy the content.


Since development of the air pollution indoor areas are more often exposed to higher air quality degradation overall. As a result, people are often exposed to medical conditions, especially in their respiratory system. Such as:

  1. Chronic obstructive pulmonary disease (COPD)
  2. Asthma
  3. lung cancer

Microorganisms lead to a number of medical conditions

Although there are a number of air purification techniques exist like filters and chemicals there was no better efficient technique to get rid of airborne contaminants.

This is where UV-C light comes into play.

How Does UV-C Light Work?

UV-C light air purification technique is using ultraviolet light’s C type in wavelength in the range of 200-280 nm.

Due to this short wavelength, UV-C light has higher energy compared which can disrupt the DNA and RNA of microorganisms. This is known as germicidal.

In general when airborne microorganisms such as,

  • Bacteria
  • Viruses
  • Mold spores

exposed to UV-C light they are neutralized by enabling reproduction.

UV-C light can be used in air purifiers to kill or inactivate these microorganisms, making the air cleaner and safer to breathe.

Comparison of UV-C Light with Other Air Purification Methods

UV-C light for air purification has several advantages over other methods. Let’s compare UV-C light with some common air purification methods:

1. Filtration

Air filtration is a common method used for air purification. When air is passed through filters, they capture particles such as,

  • Dust
  • Polle
  • Pet dander
  • Smoke

Air filters are only capable of capturing air pollutants on a relatively large scale. When smaller particles such as bacteria and viruses, air filters are not perfect enough to capture them.

In contrast, UV-C light can neutralize microorganisms regardless of their size, making it a more comprehensive air purification method.

2. Chemical Air Purifiers

Chemical air purifiers, such as those that use activated carbon or other chemicals, work by adsorbing or neutralizing airborne pollutants.

Chemical air purifiers can be effective in removing certain pollutants. But they may not be as effective in neutralizing microorganisms.

UV-C light, on the other hand, effectively kills microorganisms without the use of chemicals. It is a safer and eco-friendlier option.

3. Ozone Generators

Ozone generators are another type of air purifier that uses ozone, to neutralize pollutants in the air.

However, when you are exposed to higher levels of ozone in general ozone exposure is quite harmful.

UV-C light, on the other hand, suitable level exposure is safe for humans compared with ozone in general.

Benefits of UV-C Light for Air Purification

1. Effective against a wide range of microorganisms

UV-C light has been proven that it is quite effective remove most types of airborne microorganisms.

This makes it a versatile solution for air purification, as it can help eliminate various airborne contaminants that can cause health issues.

2. Chemical-free and environmentally friendly

Unlike some traditional air purification methods that rely on chemicals or filters, UV-C light is a chemical-free and environmentally friendly option.

It does not produce harmful byproducts or create additional waste, making it a sustainable choice for air purification.

3. Provides continuous purification

UV-C light provides continuous air purification as long as the device is turned on. It does not require replacement filters or cartridges, which can be costly and time-consuming.

This makes UV-C light a low-maintenance option for long-term air purification.

4. Safe for human exposure

UV-C light used in air purifiers is typically enclosed within the device and does not pose a risk to human exposure.

It is designed to be safe for use in occupied spaces, such as,

  • Homes
  • Schools
  • Offices.

However, it is always good to follow manufacturer guidelines for better protection in general.

5. Reduces the spread of airborne diseases

Reduces the spread of airborne diseases by UV-C light for air purification

UV-C light can help reduce the spread of airborne diseases, such as colds, flu, and COVID-19, by neutralizing the viruses that cause these diseases.

This can be particularly perfect for controlling highly crowded areas’ risk of harmful airborne transmission.

6. Can complement other air purification methods

UV-C light can be used in conjunction with other air purification methods. It is quite often noticed with filters and ventilation systems, to enhance their effectiveness.

It can provide an additional layer of protection against airborne contaminants. This is making the indoor air even cleaner and safer to breathe.

5 Best UV Air Purifiers in 2022


Is UV-C light harmful to humans?

UV-C light used in air purifiers is typically enclosed within the device and does not pose a risk to human exposure.

However, it is important to follow the manufacturer’s instructions in the first place for better safe options.

How often do I need to replace the UV-C light bulb?

UV-C light bulbs typically have a lifespan of 9-12 months. But this may directly depend on the manufacturer’s recommendation.

It is important to replace the bulb according to the manufacturer’s instructions to ensure optimal performance of the UV-C light air purifier.

Can UV-C light eliminate all types of microorganisms?

UV-C light has been proven to be effective against a wide range of microorganisms. However, the effectiveness may vary depending on factors such as 1. intensity of the UV-C light

  • Duration of exposure
  • Type of microorganism.

It is important to choose a UV-C light air purifier that is specifically designed for specific manufacturers’ guidelines.

Can UV-C light be used in all indoor spaces?

UV-C light can be used in various indoor spaces, including,

  • Homes
  • Schools
  • Offices
  • Commercial buildings.

But make sure to check its performance appropriately for selected indoor areas under manufacturers’ guidelines.

Does UV-C light have any side effects?

The appropriate level of UV-C light used in air purifiers is considered safe for humans. But in general, long exposure to UV-C light can cause skin and eye irritation.

But make sure to avoid direct exposure to UV-C light under manufacturers’ guidelines.

The Importance of Proper Ventilation in Bathrooms and Kitchens


UV-C light is a promising solution for air purification with numerous benefits. It is effective against a wide range of microorganisms, is chemical-free and environmentally friendly, provides continuous purification, is safe for human exposure, reduces the spread of airborne diseases, and can complement other air purification methods.
