What is UV light sterilization and how does it work?

UV light sterilization is a disinfection method that uses ultraviolet light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. This method is effective against a broad range of pathogens, including bacteria, viruses, and mold spores. The process involves exposing contaminated surfaces or air to UV light of a specific wavelength, typically within the UVC range of 200-280 nanometers, which is known for its germicidal properties.

What challenges are associated with UV light sterilization in hospitals?

While UV light sterilization is a powerful disinfection tool, it faces several challenges in hospital settings:

  • Dust Accumulation: Dust on the lamps can shield microorganisms from UV exposure, reducing the system’s effectiveness.
  • Shadowing Problem: Objects and uneven surfaces can create shadows, leaving some areas untreated.
  • Dependency on Proximity and Duration: The effectiveness of UV light sterilization depends on the proximity of the light to the surface and the duration of exposure. Ensuring all areas receive adequate UV exposure can be challenging.
  • Need for Multiple Lamps: Large spaces may require several UV lamps to achieve effective coverage, increasing complexity and costs.

How does the AirROS system differ from traditional UV light sterilization methods?

The AirROS system represents a significant advancement over traditional UV light sterilization methods by utilizing High Voltage Controlled Pulse (HVCP) technology to generate nonthermal plasma. This plasma produces Reactive Oxygen Species (ROS), such as hydrogen peroxide and safe low levels of ozone, which destroy pathogens both in the air and on surfaces. Unlike UV sterilization, the AirROS system does not rely solely on direct exposure or proximity, allowing for more comprehensive and consistent disinfection throughout a space. Additionally, the AirROS system can control odors and integrate with existing PLC/controllers, offering a more versatile solution for hospital sanitization.

Yes, the AirROS system is designed for ease of integration into existing hospital environments. Its versatile design allows it to complement current in duct HVAC systems or operate as a standalone unit. This flexibility ensures that hospitals can implement AirROS without significant modifications to their infrastructure, making it an accessible upgrade for enhanced infection control measures.

In what ways does AirROS offer more effective odor control compared to UV light sterilization?

AirROS offers more effective odor control by actively generating Reactive Oxygen Species (ROS) that neutralize odor-causing compounds, rather than merely disinfecting surfaces and air. The ROS, such as hydrogen peroxide and safe low leves of ozone, oxidize these compounds, effectively eliminating odors at their source. This approach is more comprehensive than UV light sterilization, which primarily targets microorganisms and does not directly address odor molecules.

How does the AirROS system contribute to reducing hospital-acquired infections?

The AirROS system contributes to reducing hospital-acquired infections by providing continuous, comprehensive disinfection of both air and surfaces. By generating ROS that actively destroy pathogens and prevent their proliferation, the system addresses not only airborne microbes but also those present on surfaces, including areas that are difficult to clean manually. This broad-spectrum approach helps to significantly lower the risk of transmission of infections within the hospital environment, contributing to a safer and healthier setting for patients and healthcare workers alike.
