UV Room Disinfection 1

UV room disinfection with UVC germicidal lamps reduces the risk of infection from harmful pathogens and pollutants. UV disinfection lamps destroy bacteria, viruses, mold, mildew, fungi, and other pollutants, including volatile organic compounds (VOCs). These pathogens and pollutants can cause illness in people and irritate breathing pathways, especially for people with asthma or immune-compromised conditions.

UV room disinfection helps to freshen the air and clean surfaces to make buildings and homes safer and healthier.

Why UV Room Disinfection is So Important

UV Room Disinfection 2

According to the Environmental Protection Agency, EPA, people in the U.S. spend about 90% of their time indoors, where pollutants can be as much as two to five times higher than in typical outdoor concentrations. The impact of indoor air quality (IAQ) on the health of people is important for many reasons.

The people who can be most susceptible to pollutants, such as the elderly, young children or people with respiratory or cardiovascular disease, typically spend more time indoors than other people.

Concentrations of some indoor pollutants have increased in recent years due to the increased use of synthetic building materials, pesticides, cleaners, furnishings, and energy-efficient building construction that can lack sufficient ventilation and air exchange.

Types of Building Pollutants

UV Room Disinfection 3Many types of pollutants can affect the indoor air quality of buildings or residential homes, which can originate from indoor or outdoor sources. UV room disinfection can help combat many of these indoor and outdoor pollutants for cleaner air and surfaces.

Indoor pollutants come from a wide range of sources and may include:

  • Biological agents such as molds
  • Natural origin substances such as pet dander, radon
  • Volatile organic compounds from various materials and products
  • Combustion byproducts such as particulate matter, carbon monoxide, and tobacco smoke

Most pollutants that affect the quality of indoor air come from inside the building, although some sources may originate from outdoors as well.

Outdoor pollutants can enter a building through open doors, windows, or cracks in structures and include:

  • Smoke from chimneys
  • Contaminated groundwater or soil
  • Volatile chemicals in water supplies
  • Pollutants on clothing or shoes carried indoors

Poor Air Quality Effects on Human Health

UV room disinfectionPoor air quality can have serious adverse effects on human health. UV room disinfection systems can significantly improve indoor air quality and have beneficial health effects. Some of the most common health hazards associated with indoor air pollutants include:

  • Headaches, fatigue, dizziness
  • Heart disease
  • Cancer
  • Irritation of the eyes, throat, and nose
  • Respiratory disease and exacerbation of asthma systems

Respiratory disease can include many diagnoses with various symptoms. Many indoor air pollutants are triggers for asthma attacks, such as dust mites, mold, allergens, pet dander, tobacco smoke, particulate matter and other pollutants that can make asthma much worse.

Another respiratory illness, Legionnaires’ disease, is a type of pneumonia that is caused by exposure to the Legionella bacterium and has been directly related to buildings that have poorly maintained heating and cooling systems. There is even a term to describe when people feel sick entering a particular building, and their symptoms diminish upon leaving; this is called “sick building syndrome.” UV room disinfection can help to eliminate this and many other health hazards from poor indoor air quality.

Types of UV Room Disinfection SystemsUV room disinfection

UV room disinfection systems can come in various types and forms, such as:

There are many ways that people can disinfect the air and surfaces with UV germicidal devices. UV air purification systems can be used in conjunction with UVC robots in places like hospitals to help prevent the spread of airborne disease and to disinfect surfaces. UV radiation in the UVC wavelength, the shortest wavelength, is most effective at eliminating viruses and bacteria and is proven to eliminate many pollutants including mold, mildew, and fungi.


Many of these types of UV disinfectants are used in a wide range of settings to improve indoor air quality, eradicate harmful pathogens on surfaces, and prevent the risk of infection. UV disinfection systems are beneficial in just about any residential, commercial, and industrial setting such as:UV room disinfection

  • Residential homes
  • Hospitals
  • Restaurants
  • Schools and colleges
  • Daycare centers
  • Long-term care facilities
  • Commercial businesses
  • Public places like libraries, airports, bus stations
  • Industrial operations for clean air emissions

This is just a short list of the many environments where UV room disinfectants protect human health by eliminating various bacteria, viruses, pathogens, and pollutants.
