A Brief Guide to UV Air Sanitizers
If homeowners are concerned about bacteria and viruses in their home’s air, one effective way to eliminate them and improve the air quality is by installing a UV air sanitizer. This post will discuss UV air sanitizers, their advantages, and signs that a UV air sanitizer installation may be necessary.
What Is a UV Air Sanitizer?
A UV air sanitizer utilizes ultraviolet light technology to eliminate harmful microorganisms, including viruses and bacteria, from the home's air. Whole-home UV sanitizers are installed into the existing ductwork or near the evaporator coil, allowing them to sanitize the air passing through the home’s heating and air conditioning system, which will be distributed throughout the entire home. The sanitization process occurs seamlessly during normal HVAC operation. This makes them effective at cleaning the air for the entire household, rather than just one room, unlike a portable unit.
When the furnace or air conditioner runs, contaminated air flows past the UV-C light, which neutralizes viruses, bacteria, mold spores, and other microorganisms. Clean, purified air then continues through the ducts to circulate throughout the household. UV-C light technology is often used in buildings, such as hospitals and restaurants, because it helps keep the indoor air clean and sterile. So, it’s a great way to ensure cleaner air in the home, creating a healthier living environment.
Benefits of Installing a UV Air Sanitizer
Installing a UV air sanitizer helps protect against harmful microorganisms circulating through the home and ductwork, thereby improving indoor air quality and creating a healthier living environment for the family. UV sanitizers reduce bacteria, viruses, mold spores, and other allergens and microorganisms that trigger illnesses, allergies, and respiratory issues.
Beyond cleaner air and health advantages, UV air sanitizers can also help the heating and cooling equipment operate more efficiently by preventing microbial buildup on coils and internal components. When the system operates more efficiently, it reduces energy consumption and lowers operating costs.
Signs to Install a UV Air Sanitizer
Some situations that can indicate a UV air sanitizer may be needed include if people in the home experience frequent allergy or asthma symptoms, or have other respiratory conditions, causing symptoms like coughing, sore throat, a runny or stuffy nose, fatigue, and more. If people in the home frequently get colds or are often sick, this can also indicate the presence of airborne contaminants and microorganisms in the home’s air.
Additionally, if the home has a mold problem, it may also indicate that a UV air sanitizer installation is needed, as UV air sanitizers can help remove mold spores as well as other microorganisms. Mold spores can travel through heating and air conditioning systems, triggering allergic reactions and respiratory distress. Mold may be visible, or homeowners may be alerted to it through a musty odor. However, it’s important to note that the underlying cause of the home’s mold problem should also be addressed because a UV air sanitizer will not address the root cause of mold growth.
