Best UV Light for HVAC System

UV-C light technology can be effective in killing germs and mold in your indoor air. Installing a UV germicidal lamp might help people with allergies or respiratory issues reduce their symptoms.

Before you buy one to install in your home, it is vital to know what is the best uv light for hvac system, and how to choose the most effective option for your home. Here are some key factors to consider:


Intensity determines the ability of the light to kill germs. It is calculated by dividing the output power by the area width, and then multiplying that by the duration of exposure. Hence, the higher the output power, the faster and more effectively it will sterilize your indoor air.

Input Power

Input power means the amount of energy the system needs to consume in order to run. The lower that is, the more money you can save on your electricity bill at the end of the month. Many people fail to consider this factor, causing them to spend more money in the long run without even realizing it.


Brand reputation can help you predict the quality and durability of an appliance. Even if they have the same specifications, a more expensive product from a reputable brand will likely last longer than a cheaper unit from an unknown brand. Some of the best induction range brands are GE, Cafe, KitchenAid, Bosch, Frigidaire, NuWave, and Duxtop.

Ozone Level

Certain wavelengths of UV might emit ozone, which is harmful to our health. The gas can irritate your skin, eyes, and even lungs if you inhale it. Ozone is also bad for the environment due to its carbon footprint. To make matters worse, it can cause corrosion in your HVAC system. If you have to buy a UV light, make sure you buy one with an ozone-free label.

Another important thing to recognize is that there are two types of UV light for room sterilization. Both have different systems to kill air pollutants. Check to see which one will suit your needs better.

Air Sterilization

This UV light cleans the air that circulates through your room. You install this device on your return air duct, and it kills all the germs carried by air that pass by the light. However, this mechanism runs only when the AC is on. If you turn your AC off, the UV light will go off as well.

Coil Sterilization

Instead of cleaning the air, this UV light stick is responsible for cleaning the air handler coil, where mold and bacteria usually grow. The light runs all the time without stopping, even if your AC is off.

The easiest rule of thumb is that you can expect higher quality from more expensive units. However, impulsively buying the most expensive one you can get is not a wise choice, as you might end up with a unit that doesn’t match your needs. If you are unsure which one to pick, ask for some recommendations from professional technicians about the best uv light for hvac system choices.
