The PYURE Air and Surface Sanitization system is an efficient and effective solution against pathogens that improves air quality and sanitizes surfaces without harming people or equipment in the room. The system has shown to be safe and highly effective at reducing bacteria, viruses, mold, and odor-causing compounds in occupied spaces.
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 continue to remain and react, keeping the air safe to breathe.
PYURE produces concentrations of Hydroxyls and organic oxidants similar to what is naturally generated outdoors1 – recreating the cleansing action of the sun 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.)
PYURE offers more benefits than other air purification and surface sanitization methods. PYURE solutions are designed to complement existing sanitization practices, delivering higher levels of protection and improving staff and patient safety.

* Hydroxyl production is restricted to the catalyst surface, very limited production of organic oxidants
** Reactivity of ions and O2 are short lived, effect drops off quickly as distance from ion source increases
***At concentrations that are safe for human exposure (less than 1 PPM), pathogen reduction is limited
Hydroxyls are a naturally occurring and important sanitizing agent in the outdoor environment. Hydroxyls decompose natural and man-made pollutants, killing pathogens and keeping air safe to breathe. However, Hydroxyls do not exist naturally indoors, as they are consumed within milliseconds when produced by sunlight. Pyure Technology® is capable of producing the same concentrations of hydroxyls and natural oxidants found in nature to purify and sanitize indoor areas.
PYURE Technology® kill rates for airborne pathogens offer a greater than 99% reduction within 30 minutes time, and a detection efficacy rate of 100% after a range of 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.
PYURE Technology® effectively treats air and surfaces by recreating the natural cleansing action of the sun indoors, delivering safe and powerful performance. Additionally, Hydroxyls are working 24/7 compared to traditional line of sight UV, which is an event based treatment.
Although the PYURE In-Duct Unit (IDU) can be used as standalone equipment, the IDU 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 is capable of providing protection for large areas, including entire buildings.
With its continuous protection, PYURE technology® offers a more efficient process that does not create unwanted downtime. Hydroxyls are safe for people to be present 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.
Pyure Technology® is designed to bring the cleansing power of the sun indoors. The PYURE In-Duct Unit (IDU) can be used for protection against airborne pathogens in the operating environment, office spaces, waiting areas, and anywhere cleaner air is desired.
The IDU™ series comes in two models, designed for optimal performance and safety within the treatment (coverage) area (as defined by ASHRAE 170) when used in typical Operating Room (OR) environments (20-30 ACH, 80-87% air recirculation, 68° - 75°F (20°- 24°C) room air temperature, 20 – 60% relative humidity and 10 foot (3.5m) ceiling height). A particular model selection is based on the size of the operating room floor area (see table below) and use of the "High" (2-optics) setting.
|Model||Operating Room Floor Area|
|IDS02 – PYURE In-Duct Unit Sterile Field||300 ft2 – 500 ft2 (27.8 m2 – 46.5 m2)|
|IDB02 – PYURE In-Duct Unit Sterile Field||500 ft2 – 900 ft2 (46.5 m2 – 83.6 m2)|
PYURE offers dynamic protection and air quality improvement by using hydroxyl generation to mimic the way sunlight sanitizes our outdoor environment. The PYURE In-Duct Unit is equipped with two hydroxyl generating optics, and is designed for continuous operation.
