What Do UV Air Purifiers Do for Your Home?

Does your home have poor indoor air quality? Are you or a family member fighting an illness? The culprit might be airborne pathogens like viruses, bacteria, and mold spores that people inadvertently breathe in and cough out. They are then recirculated through your HVAC system and can sicken others.

To reduce indoor air contaminants, ultraviolet (UV) air purifiers are air cleaning machines that kill pathogens, improve ventilation, and produce cleaner and safer air.

What is a UV Air Purifier?

UV air purifiers use light waves to attack fungus, mold, mildew, bacteria, and viruses.

Invisible to humans, catching and killing pollutants can improve your overall health and HVAC efficiency and remove noxious odors like burnt food or cigarette smoke.

How Do UV Air Purifiers Work?

When air goes through a UV air purifier, it sends out short-wave UV light that deactivates or breaks down pollutants or pathogens. The process takes a few seconds to damage and corrupt DNA and RNA, making them unable to function or repopulate.

UV light is broken into three spectrums:

  • UV-A-Light (315-400nm): As the longest wavelengths, these make up 95% of the sun’s radiation.
  • UV-B-Light (280-315nm): One of the shortest wavelengths, these damage DNA and RNA and can cause sunburn.
  • UV-C-Light (200-280nm): As the other shortest wavelengths, these are useful in air purification systems to damage bacteria and viruses.


What Indoor Air Pollutants Do UV Air Purifiers Protect Against?

The EPA defines common indoor air pollutants based on the type of pollution. These include:


Found in flooring, fireproofing, and insulation materials, inhaling asbestos fibers can cause mesothelioma and lung cancer. UV air purifiers with HEPA filters and UV-C can catch and remove these tiny airborne fibers.

Biological Pollutants

Responsible for exacerbating respiratory infections, biological pollutants include allergens and organisms like viruses, mold, and bacteria. Photolysis absorbs photons in an excited state to break their chemical bonds.

Carbon Monoxide

An odorless and colorless gas produced from burning oil, gas, or propane, CO2 causes nausea, dizziness, headaches, and death. Photocatalytic oxidation (PCO) is a technology that reacts with UV light and creates oxygen to break down these pollutants.

Emissions from Heaters and Cookstoves

Caused by emissions from burning fossil fuels, matter can get deep into the lungs. Air purifiers with a high Clean Air Delivery Rate (CADR) can improve air quality.

The Benefits of Installing a UV Air Purifier in Your Home

UV air purifiers can improve your HVAC functionality and promote optimal health. Benefits include:

  • Improving airflow while reducing contaminants
  • Lowering energy and HVAC maintenance costs
  • Cleaning and unclogging your HVAC and making it more efficient
  • Reducing allergies and preventing respiratory problems
  • Destroying harmful microorganisms in humid or damp spaces

Combining UV Air Purifiers with Other Air Filtration Systems

When exploring a combined approach to air purification, UV purifiers can work with forced air systems and HEPA filters to clean the air.

As air runs through your HVAC system, UV-C light effectively inactivates microorganisms by damaging their DNA or RNA.

Other types of filters & purifiers include:

  • Filtered air purifiers: Filtered air purifiers capture pollutants and trap them in activated carbon or HEPA filters.
  • Electrostatic air purifiers: These purifiers trap particles that fall to the ground. An example is an ionizer.
