How Do HVAC UV Lights Work?
Each new season brings with it a new set of challenges.
Summer is synonymous with allergies and related health problems associated with bioaerosols (airborne contaminants composed of living organisms), dust, and other particles floating around the air.
If you want to maintain your indoor air quality this spring, one of the best ways to protect your home against mold spores, dust mites, and bacteria is to install a UV germicidal light within your existing HVAC system.
What is ultraviolet (UV) germicidal air irradiation?
Ultraviolet (UV) light is a natural cleansing technology that can is used to disinfect and clean air, food, water, and much more. Since UV light is present in the natural rays from the sun, that’s part of the reason why outdoor air is often cleaner and safer than indoor air.
First, let’s find out what UV light does:
Ultraviolet light is found naturally in the rays of the sun, affecting nearly all living organisms. While it can destroy bacteria by scrambling their DNA, most of the sun’s UV rays are blocked by our planet’s ozone. Unfiltered UV light in residential and commercial settings, however, is much more powerful and can disinfect 99.999% of all known bacteria, viruses, mold, and protozoa.
If you have a respiratory problem or suffer from allergies, you may benefit greatly from a UV light air cleaner.
UV light naturally interacts with organic materials and disrupts their ability to live and reproduce. So, while air filter and other capture systems are pretty effective at capturing the contaminants in your home, only UV light can kill them at the source.
UV light destroys microorganisms in the home, which is not only great for your health and allergies, it also helps keep your HVAC system clean to reduce the need for maintenance, repairs, and replacements.
UV lights can be installed in different areas of your indoor air handling system or your ductwork to kill airborne microorganisms and bioaerosols floating around the home.
UV Air Cleaner Benefits
Your UV light is on whenever your HVAC system is in use. It automatically kills airborne biological contaminants.
2. Easy Installation
A qualified HVAC technician will be able to install a UV light cleaner in as little as one day. The installation is simple, but the effects last the lifetime of your HVAC system.
While UV light does raise the risk of cancer and can have other harmful effects from over-exposure, the UV light in your HVAC system will never harm anyone in the home. The UV lights are also calculated to emit a safe dosage of light (around 16,000 microwatt seconds per square centimeter).
Your heating and air conditioning system naturally creates condensation. If this moisture is left unchecked within your ducts and HVAC system, it can create a perfect breeding ground for mold, mildew, bacteria and fungi.
A UV germicidal lamp is installed within your existing system where such contaminants are most likely to grow. The UV light neutralizes these pollutants and keeps them from spreading throughout your ducts and home.
While other air filtration and cleaner systems simply trap airborne contaminants, UV lights actually sterilizes the viruses, germs, and other biological contaminants. That’s why hospitals utilize UV lights in their buildings. You don’t just want to trap the contaminants; you want to eliminate them.
