Can HVAC UV Lights Improve Air Quality In Your Home?

Ultraviolet lights, also referred to as UV lights, have been used for years in hospitals, schools, and businesses to purify the air, water, food, and more. Did you know that this purification UV technology is also a convenient and affordable option to be installed in homes? Customers who prioritize the air quality in their homes are opting to install whole home air purification systems. Indoor air can be up to five times more polluted than the air outside. In fact, the EPA (United States Environmental Protection Agency) explains this data is true whether a home is located in a rural or highly industrial area.[1]

Investing in your air quality is important because your health is important! There are many factors negatively impacting the air inside homes and businesses. For instance, poor indoor air quality results from inadequate ventilation, pollutant sources such as building materials, paint, varnishes, sealants, off-gassing from furniture, carpets, wood products, household cleaning products, personal care products, and fragrance, as well as pollutant sources found outside the home (for example, pesticides, radon, and outdoor air pollution). If your home is not well ventilated, then these pollutants can accumulate to unhealthy levels. Research shows that irritation to the eyes, nose, and throat, as well as headaches, fatigue, and dizziness are often linked to poor air quality. Additionally, it’s important to realize that the negative health effects from poor indoor air quality may not show up until years after the exposure.[2] According to the EPA, health effects such asthma, allergies,  respiratory diseases, heart disease, and cancer can be traced back to exposure to indoor air problems.

How UV Lights Improve Indoor Air Quality

Do UV lights improve air quality? There are a variety of HVAC UV light air cleaners available that do a great job at cleaning the air. In general, UV lights remove contaminants in the air, such as, germs, mold, bacteria, dust, pollen, dander, and viruses by emitting low levels of UV radiation.

Consider that sunlight is an incredible disinfectant, as it has the ability to create hydrogen peroxide and release it into the outside air, and sunlight helps rid microorganisms outside.[3] This is similar to what HVAC UV light air purifiers, such as the REME-HALO® and the HALO-LED™ do. These air cleaners disperse natural concentrations of gaseous hydrogen peroxide throughout the home which reduces mold, bacteria, viruses, and smells in a matter of minutes. So, can UV lights improve air quality? Absolutely!

HVAC UV light installation for air quality purposes is becoming a popular option for customers in Wichita, Kansas who understand that for the air inside of their homes to be healthy, action must be taken!

HVAC UV Light Installation and Maintenance

There are many HVAC UV light air cleaner systems available. Most of these UV light systems have one to three UV bulbs near the HVAC system’s evaporator coil. UV lights for HVAC systems are often placed near the evaporator coil because evaporator coils produce condensate, which results in a moist and dark environment – the common playground space for bacteria, mold, and other contaminants.

HVAC UV light installation is generally an easy, straight forward process. You may be wondering how long it takes to install air purification HVAC UV lights, and the answer is that it will depend on your existing HVAC system. However, know that the installation process usually takes around one to two hours. Additionally, HVAC UV light air purification systems are easy to maintain. HVAC UV lights only require bulb replacement on occasion, which can be taken care of by an HVAC professional during your HVAC preventative maintenance appointments.

Best Whole Home Air Purification Systems

It’s easy to become overwhelmed when trying to determine the right air cleaning system for your home because there are so many systems available, such as, ozone generators, carbon filters, mechanical filters, electronic systems, and ionization systems. All of these systems have the primary goal of collecting airborne contaminants.

Larry Cook Heating and Cooling recommends the REME-HALO® or HALO-LED™ whole home in-duct air purification systems. We’ve found that our customers are very happy with these air purification systems! The REME HALO® uses technology, in addition to UV light, to clean and improve air quality. This system can be installed in most central air conditioning systems. It is able to proactively send ionized aggressive oxidizers into the indoor air to get rid of pollutants in the air and on surfaces. When tested, the REME HALO® was able to kill H1N1 on surfaces with 99+% rate, and it is able to remove 99% of microbes in human sneeze within 3 feet, 97% of airborne bacterial reduction, 85% odor reduction, 97% airborne mold reduction, and more! Another great whole home in-duct air purification system is the HALO-LED™. This system works similarly to the REME HALO® and is zero ozone certified with improved energy efficiency.
