Using UV Light to Improve Your Indoor Air Quality


As a homeowner, you want your refuge to be a safe and healthy place for you and your family to relax. This may mean ensuring that your home is air tight and sealed against the outside environment. While sealing off your home can prevent the outside world from coming in, it can also cause poor indoor air quality.

What Causes Poor Indoor Air Quality?

Poor indoor air quality can be caused by a number of contaminants, including:

  • Pets: Pet dander, which consists of hair and skin, can be shed. When it gets into the duct system, it is often re-circulated throughout the home. Some occupants can be seriously allergic to this dander.
  • Mold: Mold can grow in areas that are often wet. This includes bathrooms and the attic. When those spores bloom, they can get into the air and circulate to other parts of the home. Some types of mold are toxic and can make occupants feel ill.
  • VOCs: Volatile organic compounds, known as VOCs, are chemicals that release large amounts of molecules that may have negative health effects for occupants of the home. Certain cleaning supplies, cooking, carpeting, non-electric space heaters and certain types of paint all contain VOCs. Some VOCs have a noxious odor while others don’t.

 

How do UV Lights Help to Purify Indoor Air?

UV light air purifiers work by using ultraviolet light to inhibit the growth of mold spores germs and some types of bacteria that may be hanging out in the duct system. This prevents harmful contaminants from circulating throughout your home. When installed in the home, the UV light works in a cumulative manner to clean the air. As the air passes over the light, more contaminants are killed off or are removed from the circulating air.

There have been numerous studies conducted by Penn State University, Harvard School of Public Health, General Electric and others that have proven that UV light has the ability to cause damage to DNA in germs, bacteria and mold. In fact, the Centers for Disease Control and Prevention recommends that hospitals use UV light to prevent tuberculosis bacteria from being transmitted via the hospitals’ inside air.

What are the Advantages of Installing a UV Light Air Purifier?

UV light air purifiers are installed directly inside your cooling and heating unit. This prevents the UV light from being harmful to any of the home’s occupants while killing bacteria, mold and germs where they are most likely to grow. Because the contaminants are not multiplying or collecting in the ducts, the UV light keeps the coils clean, preventing them from needing routine maintenance or even cleaning, a process that can be expensive. Even further, the odors caused by pets or normal, everyday activities are also reduced. When it comes to maintaining the UV light, many types simply need to have the lamp replaced just once a year.

Do I Really Need a UV Light Air Purifier?

If you share a home with pets, family members who have allergies or family members who enjoy cooking and crafting with glues, paint or adhesives that leave an odor, a UV light air purifier can help reduce contaminants that could have an impact on your indoor air quality. Because these UV lights also can increase the efficiency of your HVAC equipment, those who have these lights installed generally find that their HVAC unit does not have to work as hard to keep the temperature consistent.

Ultimately, installing a UV light can be extremely beneficial for homeowners. If you feel that a UV light might improve your indoor air quality, contact us so we can find the right option for you.
