Your home should be a place where you feel comfortable, relaxed, and most importantly, safe. To keep your home working efficiently, several units are needed, such as an air conditioner and a furnace. While these units help improve your home, they could be harmful to your home’s air quality if not properly maintained. 

Luckily, UV lights have been proven to be an effective defence against this poor air quality. Keep reading to learn how UV lights can help your HVAC system and keep your home full of clean, safe air. 

What’s Concerning About Poor HVAC Air Quality

Your home’s air quality should never be underestimated. While having poor air quality won’t have a significant impact on your family right away, it can become dangerous over time. The effects are especially dangerous for children and seniors.

Poor air quality can cause the following:

  • Eye irritation 
  • Nose irritation 
  • Throat irritation 
  • Shortness of breath 
  • Asthma 
  • Respiratory conditions 
  • Cardiovascular system complications 

These health issues are caused by buildups of viruses, mould, fungi, and bacteria in an HVAC system. If anyone in your family has allergies, asthma, or a compromised immune system, keeping high air quality in your household is especially important. 

How air purification systems use UV light to enhance air quality

How UV Lights Work

To keep the clean air flowing through your home, both air purifiers and air filters work together in your HVAC system. Your home’s air purification system kills the microorganisms that are found in your HVAC system. Meanwhile, your air filter removes particles from the air. 

Your home’s furnace filter protects your family from harmful substances such as:

  • Dust 
  • Pollen 
  • Pet hair and dander
  • Smoke and fumes 
  • Mould spores and mildew
  • Bacteria 
  • Viruses 

To remove microorganisms from your HVAC before they are released into your home, air purification systems use UV light. While many people may associate UV light with a sunburn or freckling, your HVAC system uses it for a very different purpose. 

In fact, clinics and hospitals use UV lights to keep surfaces clean and disinfected. In your HVAC system, a special type of UV light is used, UV-C light. This light is harmless to humans but is still able to kill microorganisms in your home.  

As these harmful microorganisms pass through the air purification system, they absorb the light. The UV-C light then damages the DNA of the microorganisms and makes them harmless for humans. 

The UV-C light damages the following microorganisms:

  • Viruses 
  • Mould 
  • Fungi 
  • Bacteria

Your HVAC Purification System 

To keep the air in your home safe for your whole family, both an air filter and a purification system are needed. The air pollution within your home is only made up of 35% particles (the substances the air filter stops). If your home doesn’t have the proper air purification system, 65% of the harmful substances that cause air pollution can still be getting into your home. 


The APCO-X is an effective UV light air purification system for your home. The system uses both UV-C light and a carbon filter in your HVAC system. The system’s UV light kills microorganisms while they pass through the system. Meanwhile, the system’s carbon filter reduces the particles passing through. 

One of the many exciting features of the APCO-X system is its clean coil system. The clean coils provide extra UV-C light, helping to further prevent the growth of mould within your HVAC system. Whatsmore, the system is certified green, emitting 0 ozone into your home. 

Watch the difference the APCO-X air purification system makes in your home.

Goodman DMH900 Whole-House HEPA Air Cleaner 

The Goodman DMH900 Whole-House HEPA Air Cleaner is another effective system to keep your home’s air clean and safe for your family. The system uses a HEPA filter and a carbon pre-filter to block particles from escaping into your home’s air. These two filters work together to gather almost all of the harmful particles. The carbon pre-filter removes the larger particles and the HEPA filter the smaller particles. 

In addition to the air filter, the Goodman DMH900 Whole-House HEPA Air Cleaner also uses UV lights in its purification component. Together, the system is 99.97% efficient at removing particles as small as 0.3 microns. 

Watch as the Goodman DMH900 Whole-House HEPA Air Cleaner works to create clean air for the whole home. 

Keeping Your Home’s Air Quality Safe

Your home’s air quality is not something that should be neglected. Whether members of your family have pre-existing health conditions or they’re completely healthy, clean air is important for everyone. Using UV light, your home’s air purification system is able to keep your family and HVAC system safe.
