After two recent studies from Japan and Colombia University, USA, we have a better idea of the effectiveness of UVC light. UVC light is now considered one of the most effective weapons against COVID and other viruses for the home and professional workplace.

UVC air sanitation reviews

UV light can kill microscopic organisms such as bacteria and viruses by destroying their cells. However, some UV light can also damage human DNA, cause eye and skin damage and increase the risk of cancer. It is therefore of utmost importance that you purchase the right system from the right company. 

Please don’t just buy any cheap system form Ebay or similar online sites. It is important to read technical reviews and any accreditations or certifications for any system available online. 

You can spend a lot of time on sites like Amazon, and if you have, you’ve probably seen a device that promises to disinfect things in your home. Many of these systems come with a so-called series of shorter UV wavelength bulbs. These are not as effective as other systems on the market.

 However, it has been found that there are certain wavelengths of UV light that are safe for humans and can kill coronaviruses on the surface and in the air. There are others which are more powerful and can cause issues when you are in the room.

UV Light and Disinfection

The Earth’s atmosphere prevents UVC from reaching us, so we do not have to worry that our skin and eyes will be damaged by longer wavelengths of UV light.

However, there is a problem with the use of UVC light in disinfection: it takes a certain intensity to kill microbes quickly. It has been used for decades in hospitals and medical facilities to clean and perform its work. Depending on the application, however, it can reach tiny corners and angles that are otherwise difficult to sanitise.

The other problem is a little more worrying: for low-power appliances sold to consumers, the appliance must remain sealed to disinfect it effectively. This requires sufficient exposure to UVC light from all sides, and this requires the use of a high-voltage supply, such as a fluorescent lamp. Some cheaper systems with no safety protocols can cause DNA mutations in skin and eyes caused by germicidal bacteria, some of which are considered carcinogenic.

Hospitals are taking extreme measures to ensure their safe use, which the average consumer would certainly not do, but hospitals are taking these measures to make the use of low-power UV light safe for the general public.

People in the general public have been asked to wash their hands more often with soap and water. They are also being asked to wear masks and keep a safe distance from others of at least two metres. 

There has however been some back and forth regarding how long the virus stays active in the air in aerosolized particles. This has led to these further studies trying to ascertain the effectiveness of UVC light in killing airborne and surface particles.

Due to this, scientists have now discovered that far-UVC light is showing extremely promising results in ceiling SARS-COV-2 virus particles both in the air and on surfaces. 

How Quickly UVC light Kills Viruses

UV light in about eight minutes has so far killed 90% of the coronaviruses in the air, and a Columbia University study published in June 2020 found that a single dose of ultraviolet (UV) light from a disinfectant could kill the previously aerosolized two common coronaviruses. According to the study, it took about 25 minutes for 99.9 percent of the viruses to be killed. It has been shown that UV light is able to kill the virus on almost every surface and in the air to a high rate of effectiveness. 

The founding chairman of the International Association for Ultraviolet Radiation, Dr. Robert L. Hahn, recommends minimizing exposure to Covid 19, but also using UVC systems to sanitise areas that are important..

Another study by the University of Hiroshima confirmed in tests conducted in a more controlled environment that UVC light effectively kills viruses caused by Covid 19. The researchers exposed viral cultures to styrofoam sheets from a remote subway bulb and killed 99.7% of the viruses in just 30 seconds.

Therefore, the Japanese study found that one UVC system is enough to kill the virus in a large room or office space. It can kill the virus as per their tests in as little as 30 seconds!
