Purifing Indoor Air Quality with UV Lights

Purifing Indoor Air Quality with UV LightsThe lights are placed within the ductwork or air handler of HVAC systems where nearly all the air in your home passes over it. UV light is hazardous to eyesight and they’re out of sight inside the HVAC equipment.

How UV Systems Compare

Compared to other kinds of air purification equipment, UV lighting offers:

  • High energy efficiency. The new generation of UV lights use LED technology and require annual replacement. Air purifiers rely on filters that need replacement as often as semiannually that can cost much more than the UV light bulbs.
  • Low maintenance. Since they’re out of sight, UV lights require little maintenance, especially if you keep the air filter for your HVAC system clean.
  • Protection against VOCs. These gases are among the most common airborne pollutants in the typical home. They come from products made from hydrocarbons and have varying degrees of toxicity. The lights are the only way to reduce the VOC load in the air without relying on year-round fresh air ventilation, which isn’t realistic during the summer or winter.
  • Odor-free. UV rays eliminate much of the need for disinfecting air sprays that have overpowering scents that may even include VOCs. Air sprays only offer spot protection from the spread of infectious germs, while UV lighting systems protect the whole home.
  • A cleaner HVAC system. The lights will eliminate mold growth inside the air handler and the ductwork. When mold grows inside the air handler on the evaporator coil, cooling efficiency drops and air quality declines.

Cleaner, healthier air is easy to achieve by using UV lights in your HVAC system. To learn more, contact Roth Heating & Cooling, proudly serving homeowners in the greater Portland area.

Considering Improving Your Home’s IAQ by Using UV Lights? Here’s What to Know

Considering Improving Your Home's IAQ by Using UV Lights? Here's What to KnowYou may not spend a lot of time thinking about the quality of the air inside your home. However, clean air can help keep everyone in the home healthy. It has even greater benefits for allergy sufferers and for those with breathing difficulties. Improving your indoor air quality, or IAQ, is a fairly easy task that offers a great return on your investment.

What Affects IAQ?

The quality of your air can be affected by many factors. If you have smokers or pets in the home, if you have pollen-bearing plants in your yard or neighborhood, or if there’s a major roadway nearby, your air may not be as clean as you’d want it to be. Other factors affecting IAQ include having lots of dust in the air or high levels of humidity that might encourage mold growth.

What Improves IAQ?

The first, and simplest, fix for your IAQ is a good filter for your HVAC system. If you replace it regularly, a filter will catch many of the larger allergens and contaminants that get into your home.

Filters aren’t sufficient to catch the smallest particles, however. They also don’t do much about mold or mildew growth inside your ducts or around your A/C’s evaporator coil.

To take care of these contaminants, many homeowners opt to install UV, or ultraviolet, lights inside their ducts or near their evaporator coils. These lights work at a wavelength that attacks bacteria and mold spores. The lights disrupt the contaminants’ DNA, preventing them from reproducing and shortening their lives.

Since UV lights are installed within the HVAC system, they have no effect on the people or pets living in the home. These lights are remarkably effective. They have been shown to improve IAQ in less than an hour after being turned on, and they continue to clean the air as long as your HVAC system is on. Paired with a high-quality filter, UV lights can give you the indoor air quality your family needs to stay healthy.

UV Lights: What You Need to Know

UV Lights: What You Need to KnowThe cool, rainy weather Portland often sees creates the perfect conditions for mold growth. Ultraviolet (UV) lights help keep that mold and other harmful microbes from taking hold in your home.

UV Lights Protect Your Health

Viruses, bacteria, and mold spores are present to some degree in every home. These tiny microbes circulate through the air you breathe, putting you at risk for illnesses such as cold, flu, and even strep throat. Mold spores trigger allergy and asthma attacks in those susceptible and place even healthy people at risk for respiratory infections.

UV light, the same type of light found in sunshine, neutralizes these microbes by breaking down the microbes’ DNA and rendering them incapable of reproducing. This quickly decreases the number of microbes floating around, leaving you with cleaner, safer indoor air.

The lights disinfect so effectively that they’re used in hospitals, scientific laboratories, food-processing plants, water-treatment plants, and other facilities where sanitation is critical.

Incorporating UV Lights into Your Home

The most convenient way to enjoy these benefits in your home is to have an ultraviolet germicidal irradiation (UVGI) system installed in your heating and cooling system’s indoor unit. The UV light shines into the air passing through, neutralizing the microbes in that air and allowing the purified air to flow out to your rooms. Because all the air in your home passes through the system several times a day, you’ll have clean air in every room. This type of UVGI system also prevents mold from forming in your air handler and ducts.

Because both the intensity of the light and the lamp’s position affect a UVGI system’s efficiency, these systems should be professionally installed.

Handheld UV lights are also available. These give you a quick way to disinfect kitchen and bathroom surfaces. It’s also possible to install a UVGI system in a kitchen exhaust hood to break down grease particles as well as disinfect. These systems are used primarily in commercial kitchens.

If you’d like to start using UV lights to protect your health, contact us at Roth Heating & Cooling anywhere in the Portland area.
