Do You Need A UV Light For Your AC Units?
Global indoor air quality has been in a crisis long before the current pandemic. Unfortunately, it took this situation for us to realize that we need to pay more attention to air quality if we want to be healthier. Using a UV light in your ac unit can help you to have cleaner, healthier indoor air.
How can installing a UV light in your ac unit help you? Almost 95% of the world’s population live in areas where air pollution is at an all-time high. There have been premature deaths caused by poor indoor air, in addition to millions of people living with respiratory issues every day.
Now, with the ongoing pandemic, it is even more important that the air you breathe is pure. Adding a UV light to your HVAC unit is an affordable way to reduce your risk of contracting the coronavirus.
What Is A UV Light?
Ultraviolet light was discovered in the 1800s and by 1892, scientists confirmed that it contained bacteria-killing properties. After many years of development, it is now recognized as an integral way to eliminate microorganisms from the air. It is advised that UV lights are added to the HVAC units in commercial buildings, public places, and households.
The invisible rays that come from the sun are what we know as ultraviolet light. Do you know what makes black posters glow or what causes that sunburn or summer tan? These are caused by the same ultraviolet light. It is electromagnetic radiation that comes from the sun and exists in different wavelengths and frequencies. We know the broad range of wavelengths as the electromagnetic spectrum. Ultraviolet radiation is non-ionizing radiation that is emitted by the sun and artificial sources.
There are three primary types of UV radiation. These are UVA, UVB, and UVC. They are grouped by wavelength and are measured in nanometres. The ozone layer does not absorb UVA. This type of UV light has the lowest amount of energy and is associated with skin aging and damage. It is what you feel when you walk in the sun.
UVB light can contribute to skin cancers. It does not make up a lot of our sunlight. So, nearly all the earth’s ultraviolet radiation received is UVA. The UVC radiation absorbed by most of the earth does not pose much of a threat. UV C light is the most effective at killing germs and bacteria; it is often used to disinfect the air and surfaces. UVA radiation is weaker than UVB, but it penetrates deeper into the skin and is more constant throughout the year.
Can A UV Light For An AC Unit Purify The Air?
Though not in the direct line of sight to the human eye, the air inside our homes is filled with bacteria, fungi, and other harmful levels of invisible particles. Using UV light as a form of air filter to clean the air can improve your indoor air quality.
Some bacteria and germs are deactivated after prolonged contact with UV light. UV light is installed in your air conditioners in the form of UV bulbs. Not only does this remove microorganisms such as bacteria, but it also reduces the growth of mold and mildew, resulting in improved airflow.
It is important to note that most ac units do not come equipped with a UV light or UV lamp. You should always ask your HVAC technician or supplier if your unit has one. If not, you can always purchase a UV light and have your technician install it in your unit.
By removing the contaminants in the air, you are left with cleaner air in your home or property.
The bacteria-killing properties in the UV light ensure that the air you breathe is purified and free of bacteria that can harm you. Your hvac system will be a source of light, clean air, and this air purifier kills mold, so you will have no more mold and bacteria.
Can UV Lights Kill Coronavirus?
We can confidently say that the Covid-19 virus dies after extended exposure to UV light. Recent studies have confirmed that SARS-CoV-2 is among the types of coronaviruses that ultraviolet light rays can kill. Consumers are now more interested in adding UV lamps to their ac units as a disinfectant in their homes.
UVC radiation is a known disinfectant for air. For decades, this has been used to eliminate or reduce the spread of bacteria, and for this reason, it is also called a “germicidal” lamp. The safest way to utilize UVC radiation is to use it inside your ac units to disinfect the air. People commonly use it because direct UVC exposure to human skin or eyes may cause injuries, and the installation of UVC within an air duct will not cause exposure to skin and eyes.
You need to ensure that your unit is consistently cleaned in order for the UV lamp to work efficiently. If dirt covers viruses and bacteria, the lamp cannot effectively deactivate them. Maintain a consistent cleaning schedule if you want your system to work well.
