Do you know most individuals spend 90% of their time indoors? It’s a lot of time, whether it’s office, home, or cafe. The air we breathe contains many pollutants that directly affect our health. That’s why they should have germ-free indoor air quality. It’s a comet’s puzzle where every piece matters, and while UV lights seem beneficial, they are just one part of a larger strategy to maintain a healthy home environment.
What is a UV Light?
Known as ultraviolet germicidal irradiation (UVGI), HVAC UV light is a type of light that emits powerful rays of energy designed to kill bacteria, fungi, and viruses. These lights have been functional in hospitals since the 1930s to treat various conditions, such as tuberculosis.
Where UV Lights are Installed in HVAC & How Does it Work?
Typically installed in the air handler or ductwork, UV lights are crucial in purifying the air circulating through your home. As the air moves through, it carries microscopic allergens and germs that are invisible to the naked eye. These germs are then exposed to UVC rays, the highest-energy form of UV radiation, powerful enough to kill germs and sanitize the air as it recirculates through your living spaces.
UVC rays work by emitting powerful light that absorbs into the germs, disrupting their DNA. Whether it’s bacteria or mold, once their DNA is damaged, the germs die or lose the ability to reproduce. It’s like Turning on the lights to scare away monsters—except these monsters are microscopic.
Unlike the UVA and UVB rays you block with sunscreen, UVC rays specialize in making your indoor environment safer. You can think of UV lights as artificial sunshine with greater intensity. They are capable of destroying the nucleic acids in bacteria, rendering them unable to replicate.
If you’re considering bringing this technology into your home, it’s an excellent method for keeping your air clean and reducing airborne illnesses.
Do you Need a UV Light for Your HVAC?
Adding a UV light could be a wise investment for those with a split AC system or a central heating and cooling setup. It can possibly save you sudden maintenance costs. Comparing it to a whole-home air purifier? It’s a lesIt’sstly option.
2 Common Types of UV Lights for HVAC
1. Air Sanitizing Lights
First, these lights were often horseshoe-shaped or resembling coil sanitizing lights. These are more expensive but justify their higher price tag with superior cleaning abilities. They sync in with your blower motor, meaning they’re on when your system is on. Thus, they save energy and keep your air clean. If you value peace of mind and have respiratory concerns in an indoor environment, these are worth the investment.
2. Coil Sanitizing Lights
On the other hand, if you’re interested in projects and prefer a more budget-friendly option, Coil Sanitizing Lights might be right up your alley. These lights are designed to be placed right above or next to the evaporator coil in your air handler. It’s a sweet spot for most bacteria and fungi to gather. These lights remain on 24/7, continuously killing germs.
Further, Coil Sanitizing Lights are a less expensive alternative that is easier to install than their air-sanitizing counterparts. Although they might not be as powerful in treating severe allergies, they are exceptionally good at maintaining a comfortable, bacteria-free environment around the coil. So, you can expect fewer long-term repairs.
Alternatives to UV light to Kill Molds đź¦
Don’t want to invest in UV lights for now?
You may have to do some effort and repetitive work to keep the nasty molds away. Below are some of the cheap alternatives you can go for:
- MERV Filters effectively reduce mold spores in your HVAC system:
- Trap Mold Spores: Prevent mold from circulating by capturing spores.
- MERV Rating: Ratings from 1 to 20; higher ratings capture smaller particles. MERV 8 to 13 is optimal for homes, balancing airflow and filtration.
- High-Efficiency Options: MERV 14 and above are ideal for superior air cleanliness, useful in sensitive environments, or for severe allergies.
- Vinegar: Spraying diluted vinegar on surfaces can kill mold.
- Baking Soda: Mixed with water, it can scrub mold away.
- Tea Tree Oil: A natural fungicide that can be used to clean mold spots.
- Hydrogen Peroxide: Effective at killing mold on surfaces when sprayed directly.
- Grapefruit Seed Extract: Non-toxic and effective in mold prevention and treatment.
- Borax: A natural mold inhibitor that can be used in a washing solution.
- Essential Oils: Oils like clove and cinnamon are known for their anti-fungal properties.
- Ozone Generators: Produce ozone gas that can kill mold and bacteria.
FAQs
How Long Do UV Lights Last?
Generally, UV lights are designed to last anywhere from 1 to 5 years, depending on the model and manufacturer. For instance, a Carrier coil UV light is recommended to be replaced every 9000 run time hours or annually. Meanwhile, a REME HALO LED model might only need a change every 4 to 5 years.
Yet, if the light isn’t working properly, or you notice a decline in air quality, it might be time to replace your bulb sooner. You can schedule maintenance checks or tell Ventiluxes professional technicians to wipe out the dust from the lamps which causes the strength reduction.
Can I Install a UV Light Myself?
