Air Scrubber Plus vs UV Light Technology for HVAC Unit

If you think you are breathing clean air indoors compared to outdoors, you are mistaken. Unfortunately, the Environmental Protection Agency says that indoor air is two to five times more polluted compared to outdoor air.

Hence, you can use an Air Scrubber Plus or UV lights for your HVAC system indoors to remove pollutants, dust, odor, and bacteria. However, you must be wondering what the difference between the two is? Keep reading about the basic functionality of the air scrubber and UV lights and their feature comparison.

What is an Air Scrubber Plus and How it Works?

Installing Air Scrubber Plus in the HVAC system is one of the most effective ways to purify the air. Furthermore, it guarantees to remove 99.9 percent of indoor airborne pollutants.

The air scrubber uses active UV germicidal light to disrupt the DNA of the pollutants and other contaminants to kill them finally. Hence, you can also minimize viruses, bacteria, and other allergens to disinfect the enclosed spaces.

The Air Scrubber Plus isn’t just an ordinary air filter to trap pathogens or other dirt particles. Instead, it uses the advanced ActivePure technology coupled with the proprietary catalytic process to propel the air scrubbers or molecules in the air to neutralize the airborne and surface pathogens.

These air scrubbers are charged with superoxide ions, hydroxyls, and hydrogen peroxide. As a result, these naturally-occurring antimicrobial agents destroy mold, fungus, and other pathogens. In addition, the ActivePure molecules further destabilize the shell of the bacteria, virus, and other pollutants by transforming them into harmless byproducts.

Thus, the air scrubber with ActivePure technology ensures a 99.9 percent reduction of surface contaminants in only 24 hours, which is phenomenal. Another great news is that air scrubbers work efficiently against unpleasant odors, vapors, and other germs.

What are UV Lights and Bulbs?

Invisible to the human eye, ultraviolet (UVC) radiation is one of the most powerful within the electromagnetic spectrum. Furthermore, it has the shortest wavelength among the other UV lights to disinfect non-porous surfaces, water, and air.

Hence, using UVC lights, also known as germicidal lamps, is another effective way to kill harmful viruses, bacteria, and mold. Like an air scrubber, a UV light is installed inside the HVAC system to kill mildew and odor-causing germs.

The UV light uses short waves to disrupt the chemical bonds in the DNA of viruses, mold spores, and other bacteria. As a result, it renders these pathogens harmless and ineffective in spreading diseases or causing allergies.

The HVAC UV Light Sanitizer Air Purifier uses UV light of 253.7 nm to kill the airborne contaminants that cause headaches, dizziness, asthma, and other health problems. Furthermore, you can conveniently install it in the HVAC furnace or ductwork to create a permanent defense system against moldy smells and other unpleasant odors.

Thus, the UVC bulb efficiently cleans the air by removing dust odor, pollen, mildew, and smoke even on a single pass.

How is Air Scrubber Different than UV Lights?

We have understood the basic functionalities of the UV lights and air scrubber until now. Installing any of them allows killing the pathogens, viruses, and bacteria as the air passes through the HVAC system. As a result, you can undoubtedly improve indoor air quality by neutralizing allergens, fungi, and mold.

However, an air scrubber is one step ahead of the UV lights. It stands true to its name by scrubbing the indoor air using supercharged ions to kill pathogens.

Since an air scrubber kills the air pollutants instead of trapping them, it extends the longevity of the HVAC system. Moreover, the air scrubbers kill the contaminants and other particles in the air; the motor or the filter no longer clogs. As a result, you don’t need to frequently maintain or replace the HVAC unit.

However, you should know that not all air scrubbers come with UV light; instead, some air scrubbers use pre-filters, carbon filters, and HEPA filters to remove tiny dust particles.

On the other hand, the germicidal UV light waves kill bacteria and mold before entering indoors when installed inside the HVAC system. Therefore, if you want to keep mold off the HVAC unit coil, you should install a UV light.

To sum up, an air scrubber offers a complete air filtration solution to kill germs and release clean air indoors. Additionally, it minimizes pet dander, dust, and odor from home, delivering a deodorizing effect.


More than 50 million Americans suffer from different allergies every year. Not only that but 6 million children and 17 million adults are affected by asthma only.

Whether using an Air Scrubber Plus or UV lights for your HVAC system, the goal is to improve indoor air quality. You can remove the airborne pollutants, smoke, allergens, and other airborne pollutants to breathe clean and pure air.

The Air Scrubber Plus is a dynamic cleaning solution to trap and kill bacteria and other pathogens. Lastly, it cleans and purifies the indoor air courtesy of the air scrubbers that kill the germs off surfaces, objects, and countertops.
