Product Overview

The PYURE Air and Surface Sanitization system treats airborne contaminants during active surgery at the most critical time for patients and staff. Airborne particles such as skin cells may carry bacterial loads and settle directly on a wound or be transferred to a wound after from a surgeon’s hands or the surgical instruments themselves. Since the primary cause of surgical site infections is chiefly attributable to airborne contamination, air quality in the operating room (OR) should be of utmost importance in promoting patient and staff safety. The system can run continuously and year-round, providing the potential for maximum surgical uptime. There is no need to reposition a device or exit the OR during treatment. An added benefit is that hydroxyls help mitigate odors caused by surgical smoke and cauterized tissues.

PYURE uses UV energy to transform water vapor in the air into Hydroxyls, which rapidly destroy harmful pathogens and other volatile organic compounds (VOC) and create helpful organic oxidants. While the fast-acting Hydroxyls are consumed within milliseconds, the longer-lasting oxidants remain and react, keeping the air safe to breathe.

PYURE Technology is designed to bring the sun's cleansing power indoors. The PYURE In-Duct Unit (IDU) can protect against airborne pathogens in the operating room (OR) environment, where cleaner air is desired.

PYURE Benefits and Sanitization Areas

PYURE offers dynamic protection and air quality improvement by using hydroxyl generation to mimic how sunlight sanitizes our outdoor environment. The PYURE In-Duct Unit has two hydroxyl-generating optics designed for continuous operation.

FAQs

  • What are Hydroxyls and how do they work?
    Hydroxyls are a naturally occurring and essential sanitizing agent in the outdoor environment. Hydroxyls decompose natural and man-made pollutants, killing pathogens and keeping the air safe to breathe. However, Hydroxyls do not exist naturally indoors, as they are consumed within milliseconds when produced by sunlight. PYURE Technology® can produce the same concentrations of hydroxyls and natural oxidants found in nature to purify and sanitize indoor areas.

    PYURE produces concentrations of Hydroxyls and organic oxidants like those naturally generated outdoors1, recreating the sun's cleansing action for indoor spaces.

12 to 4 million molecules/cm3 hydroxyl production similar to nature: 3 to 10 million molecules/cm3. (David R. Crosley, Connie J. Araps, Melanie Doyle-Eisele & Jacob D. McDonald (2017) Gas-phase photolytic production of hydroxyl radicals in an ultraviolet purifier for air and surfaces, Journal of the Air & Waste Management Association, 67:2, 231-240, DOI: 10.1080/10962247.2016.1229236.)

  • What is the efficacy of using Hydroxyls in air and surface sanitization?
    PYURE Technology kill rates for airborne pathogens offer a greater than 99% reduction within 30 minutes and a detection efficacy rate of 100% after 1 to 2 hours, depending on the type of pathogen. This includes COVID-19 virus, Staphylococcus E., and black mold. Performance against surface pathogens varies based on the specific pathogen and type of surface but ranges from a 94% to 99.99% reduction of viruses and bacteria.
  • How effective are Hydroxyls compared to cleaning with UV Light and other methods?
    PYURE Technology effectively treats air and surfaces by recreating the natural cleansing action of the sun indoors, delivering safe and powerful performance. Hydroxyls also work 24/7 compared to traditional line-of-sight UV, an event-based treatment.
  • Is PYURE meant to work in tandem with CLEANSUITE or as another option for laminar airflow?
    Although the PYURE In-Duct Unit (IDU) can be used as standalone equipment, it is ideally suited as an extra level of purification in addition to the CLEANSUITE System for those seeking unsurpassed levels of purification in the OR environment. The PYURE Air and Surface Sanitization system can protect large areas, including entire buildings.
  • Why PYURE Air and Surface Sanitization over other systems?
    With its continuous protection, PYURE technology offers a more efficient process that does not create unwanted downtime. Hydroxyls are safe for people to be in the room during treatment, unlike other systems like traditional line-of-sight UV. PYURE is also harmless to materials, whereas other systems can cause plastics and materials in the room to become yellowed and weakened over time.
