How Does a UV Air Purifier Work?

Because we spend many hours inside our homes, maintaining healthy indoor air quality is extremely important for the health of everyone inside. Sometimes the indoor air is polluted with cooking oil, cigarette smoke and other bacterial elements that result in respiratory conditions and other illnesses.

In recent decades, there have been many technological advances in the HVAC world that support the quality of the air we breathe inside our homes. One of those advancements is in the quality of air purifiers. In this article, we will discuss the role of the UV air purifier and how it is different from the other air purifiers on the market.

What Is An Air Purifier?

We would like to define an air purifier before we discuss UV air purifiers in depth. An air purifier is a device that cleans the air of contaminants and bacteria. It also removes bad odors and allows everyone the opportunity to enjoy a clean home environment. 

Though these devices are usually marketed toward those who have upper respiratory issues, air purifiers are a worthwhile investment for every home. They ensure the air quality and eliminate many invisible toxins. 

Sometimes air purifiers are built into the home’s AC system, and at other times, homeowners choose to purchase a stand alone air purifier. The type of air purifier you choose will depend on your budget, preferences, and your AC tech’s recommendations.

How UV Air Purifiers Work

Like other air purifiers, the UV air purifier works by absorbing the air in its unit and pushing it through a filter. As the air is filtered through the device, it is cleaned of harmful microorganisms and pathogens. After that, the air is released back into the room. The purifier continues this cycle for 24 hours a day until it is turned off. 

What Is the Role of UV Lights on an Air Purifier?

UV light has a very important role in air purifiers. The type of light that is used in these types of air purifiers is UV-C, which is strong enough to cancel out the harmful pollutants in your air. With the help of UV air purifiers, your air will be cleaned of pathogens, bacteria, mold, and viruses. 

When the air enters the chamber of a UV air purifier, it is pushed through a filter and into the part when the UV-C light is placed. At that point, the UV-C does its quiet magic to destroy the DNA and RNA of the pathogens and bacteria that are present in the absorbed air. This causes the pathogens to lose their harmful potency and provide a cleaner quality of air.

Difference Between UV Air Purifiers vs. Regular Air Purifiers

Air purifiers that have a UV bulb are generally just an extra step to ensure that your air is as clean as possible. However, there are some key differences that it has in comparison to a regular air purifier. 

While UV air purifiers rely on UV light, regular purifiers usually use a HEPA filter to capture the pollutants and microorganisms in the air. The HEPA filter does an excellent job of meeting the standard requirement for cleaning indoor air. In fact, it usually provides 99.97% efficiency in the quality of its work. Thus, making the UV light seem unnecessary for some homeowners. 

We recommend UV air purifiers for those who have medical conditions that rely on the highest quality of air. If you have small children, you may also want to consider the air purifier as well. Additionally, homes that have cigarette smokers should also purchase a UV air purifier as it eliminates the smoke and prevents secondhand smoke.
