UV Air Purifiers - UVGI System Benefits, Downsides, and More
Imagine yourself amid microbes and pathogens that you can see but your body can feel. The air you inhale indoors could be heavily infected with bacteria, fungi, mold, viruses, and god knows what. Double-up the quality of these microbes if you live or spend your time inside an area where HVAC is installed. The ducts of HVAC are a hub for all these troublemakers.
Poor quality indoor air isn’t something that you should let go of. Long exposure to microbes-filled indoor air gave birth to health concerns like congestion, lung infection allergies, and many more. When the pandemic was at its peak, people were bound to stay indoors all the time. Even if a pandemic is not there, one can spend as much as 16 hours indoors. So, it’s imperative to have safe and pure indoors.
Many consider UV light as one of the best ways to purify indoor air. This is why the market is flooded with UV air purifiers. However, one has to weigh down both the pros and cons of UV light in this situation. Let’s learn more about this topic and help you make a wise decision.
UV Air Purifiers: A Boon or Bane
Air is a mixture of many things. Dust, dirt, gasses, microbes, pathogens, and many other things are present in the air you inhale. While many of these components are harmless for humans, few are trouble-makers.
If these microbes and pathogens go beyond the permitted limit, they become a matter of concern. This is why the need for air purification arises. Air purifiers are devices designed to remove microbes and pathogens that aren’t good for humans.
One must use an air purifier if the inside of a home or commercial building features HVAC. The moisture present in the HVAC ducts acts like an ideal condition for microbes or pathogens to thrive. Hence, the air you receive from installed HVAC units is not fresh. But, it’s heavily infected with infection-causing elements.
An air purifier is an effective way to kill them all and make the air fresh and purified. While various kinds are existing, UV light air purifiers are making high waves in the market and are often referred to as the best UV air purifier for HVAC.
In this variety of air purification, UV C light is used to disintegrate the DNA/RNA or simply say, protein components of microbes and pathogens.
For your understanding, protein is what keeps these microbes and pathogens alive. Basically, it’s the life-matter of air-borne viruses, bacteria, fungi, and other infection-causing elements. If the life-matter is dead or inactive, the pathogens are of no use.
UV Air purifiers commercial or for office use features a filter, made-up of UV-C light. As the air passes through these filters, UV C light inactivates the present pathogens. This disinfected air then reaches the people sitting in the room.
Now that the meaning of a UV-based AC duct air purifier is clear, let’s try to understand whether or not it’s a great deal to crack.
First, we will talk about the pros of this product.
UV purifier with UV light is preferred over other means of air purification because:
- It’s a non-intrusive method
There are no harsh chemicals used to disinfect the air. Also, no harmful gases like ozone are emitted during its usage. Because of these two reasons, UV air purifiers are considered the safest way to purify the air.
- It’s an energy-efficient solution
Running a UV light air purifier is not an energy-consuming task. As there is no heavy machinery used, it can operate at very low power consumption. Hence, even if it’s installed in a large area, it won’t cost much.
- Its inactivation rate is 99%
UV C light is germicidal light and can kill microbes and pathogens of a wide range. It makes them so ineffective that they don’t cause any harm at all. So, it’s certain that you‘ll be able to get rid of all sorts of pathogens if you use UVC light at work. This is why CDC also recommends the installation of HVAC UV light air purifiers in high-risk areas like hospitals, schools, public transport, and commercial spaces.
These places are always crowded and are not less than an atom bomb when we’re in the middle of a pandemic. We have already observed the use of commercial UV light sanitizer in such high-risk zones.
However, it’s not flawless. In fact, nothing in the world is flawless. So, if you’re planning to invest in an HVAC UV light air purifier, we suggest you know about the cons of this technology.
The only drawback of a UV air disinfection system is that it won’t help you get rid of VOCs, odor, and some harmful gasses from the air.
As far as its efficacy is concerned, it depends on factors like:
Exposure time - For how long do the microbes remain in contact with the UV?
The wavelength of UV light - The ideal wavelength is 255 nanometers. Anything below that is useless.
Proximity - UV air purifiers are effective when the air remains enclosed.
So, you need to pay attention to all these aspects while picking a UV air disinfection system for indoor spaces. With a wise choice, we don’t think you’ll ever regret it.
The Final Say
With the best UV Air Purifier for HVAC, air purification is no longer a headache. With a 99% inactivation rate, such a UV light air purifier will help you breathe in purified air and keep you healthy.
UV light is an ideal way to deal with indoor air pollution. But, is it true? How viable is UV light as an air purifier? Is it about all gain and no pain? Paying attention to all these aspects is crucial if you’re thinking of using a UV air purifier and want to make the most out of the investments made.
