Will A UV Light Help Indoor Air Quality?

Germicidal UV Light

There is no doubt that Clarksville homeowners want to breathe clean air, but can a UV Light help? Not everyone is sensitive to indoor bacteria, mold and pet dander, while other people are extremely sensitive to them. Inhaling invisible allergens is not good for anyone’s health. Everybody can benefit from having ultraviolet (UV) lights. They can be installed inside your HVAC system to destroy harmful bacteria and other allergens before they can get into a home’s living spaces. UV Lights are also able to help keep the indoor coil of a home’s AC unit free of fungal growth. The indoor coil is often wet for many months a year which can lead to fungus growth.


Germicidal UV Light Spectrum

The light emitted by UV devices is categorized as being in the germicidal spectrum. This means they can be used to disrupt the DNA of mold spores as well as microorganisms. These microbes are often found in a person’s HVAC system where they grow and thrive mostly due to the moisture. UV rays are an effective way to disrupt the mold spores and other microorganisms in your system by not giving them an opportunity to grow. (continue below)

Media Filter

One of the first things someone should do when having UV lights installed is to consider adding a media filter. This can be installed in your home’s return ductwork. A media filter will work in conjunction with your homes other indoor air quality products. Media filters are designed to trap particles as small as one micron in size. Some filters are made to capture even smaller particles. This means it can trap particles approximately 700 times smaller than a person’s hair. It can also trap mold spores. Combining this with UV lights helps destroy anything not captured by the media filter.


Preventing Microbial Growth

There are two coils contained within your home’s air conditioning system. One is placed on the outside of a home and the other is inside. Above the furnace or inside the air handler is where the indoor coil will be located. This is a place that is wet and dark and during the cooling season water will condense on this coil. It creates an environment that is very friendly for microbes. Should biological contaminants begin living and growing on the AC system’s coil, the blower fan will then blow them into the home thru the ductwork. It is possible to stop this process before it begins. The most effective UV lighting systems are designed to focus on microbial growth on the AC coil. This is accomplished by constantly bathing the coil with UV light. Anyone interested in trying to minimize or eliminate the microbial activity inside their HVAC system should consider UV lights as an effective preventative measure.


Air Purification

Should anyone in your household have asthma or serious allergies, they will want more than just keeping their AC coil clean, they will want to have a way to have their indoor air purified. Some UV lighting systems are designed to do more than simple coil bathing. It may involve using activated carbon cells. This will eliminate volatile organic compounds (VOCs), noxious odors and chemical vapors responsible for making people feel sick. This is a way to do more than just inhibit microbial growth on an AC coil. It is a method for eliminating the most common pollutants found indoors in the air people breathe.


Decrease Odors

One of the many benefits of having good air quality is the smell. When mold and bacteria are in the air, they can impact a person’s health and cause bad odors. This is especially the case if they are allowed to fester over time. Getting a UV light purifier can be an excellent way to keep a home smelling fresh.

Bacteria-Related Illness

UV Lighting disrupts the DNA of microorganisms such as viruses and bacteria. These are elements that are always present in any home. With UV lighting, it is possible to remove a significant portion of them from the air. Doing this will also decrease the risk of experiencing an illness and could improve the general health of everyone living in your home.


Additional Air Quality Improvement Methods

Here are a few other methods to effectively improve your home’s air quality.

  • A Variable speed HVAC, as well as a whole-home dehumidifier, will help control humidity.
  • Unwanted circulation can be prevented by sealing a home’s ductwork in the crawlspace as well as attic.
  • Regularly washing and changing an HVAC system’s air filters as per the manufacturer instructions is important.
  • A whole-home assessment will help individuals see if there is any air entering their home from unwanted places such as a crawlspace or attic.

UV lighting combined with media filters is a great way to alleviate many potential indoor air quality issues in your Clarksville home. They will destroy the microbial contaminants that are found in an HVAC system. When UV lighting is used in conjunction with other strategies, your home will have healthier and more breathable air.
