SteriSpace uses compression to heat a continuous flow of air to a temperature at which biological contaminants in the air are killed. By eliminating hardy bacterial spores, vegetative bacteria, viruses, and selected volatile organic compounds (VOCs), SteriSpace technology achieves an exceptional 99.9999% (10⁻⁶ log) reduction rate—ensuring ultra-clean air in a continuous flow environment.
Its high-speed contaminant capture system works seamlessly with an integrated heat recuperation feature that not only destroys biological contaminants but also improves energy efficiency, making SteriSpace a powerful solution for critical clean air applications.
In a series of previous DoD-funded programs, SteriSpace has conclusively demonstrated in independent testing of smaller scale prototypes that it kills >99.9999% of all airborne biological threats including bacterial spores, bacteria and viruses.
Positive or negative pressure can be maintained for collective protection or post-contamination isolation in case of a biological attack or natural disaster.
HEPA filtration is the current technology that is in predominant use for protection against airborne biological threats. Where SteriSpace has been shown to kill greater than 99.9999% of the biological contaminants, HEPA filters trap the contaminants with a minimum filter efficiency of 99.97% at a particle size of 0.3 microns.
Studies have examined the effectiveness of HEPA filtration in removing small virus particles. The findings indicate that SteriSpace offers a superior alternative to existing filtration technology currently used to protect military and homeland security personnel.
Unlike passive filtration, SteriSpace provides proactive mitigation:
In response to the increasing urgency surrounding VOC emission control, scientists at the University at Buffalo, in partnership with YFS Systems, have adapted the SteriSpace air sterilization platform originally designed for clinical and military environments toward the catalytic decomposition of airborne pollutants.
The SteriSpace system naturally produces thermal energy through air compression, prompting researchers to evaluate its potential for VOC oxidation. The challenge: achieving full molecular breakdown of VOCs without resorting to high-temperature incinerators or energy-intensive oxidizers.
SteriSpace represents a cutting-edge advancement in air sterilization technology, specifically engineered to address the mitigation of volatile organic compounds (VOCs) through a process known as compressive heating.
This innovative approach, when integrated with carefully selected catalytic converters, facilitates the effective removal of gaseous pollutants and VOCs from the air stream via catalytic oxidation (Cat/OX), transforming harmful organic compounds into benign byproducts.
To evaluate the efficacy of the SteriSpace prototype in eliminating VOCs, a series of controlled laboratory tests were conducted focusing on eight representative VOCs:
Upon exposure to the catalytic system within the SteriSpace unit, VOCs were completely removed from the exhaust stream.
Carbon Dioxide (CO₂) + Water (H₂O)
Demonstrating complete mineralization of the VOCs and validating the effectiveness of the catalytic oxidation process.
These findings underscore the potential of SteriSpace technology as a robust and reliable solution for VOC mitigation in environments where air purity is critical, such as healthcare facilities, laboratories, and industrial settings.
Traditional ethylene oxide (EO) mitigation methods such as activated carbon adsorption, catalytic incineration, and chemical scrubbing typically require substantial energy inputs and rely on large, location-specific infrastructure. In contrast, SteriSpace introduces a streamlined and energy-efficient alternative.
Unlike conventional systems that require external energy sources, SteriSpace utilizes waste heat generated during routine air processing to facilitate catalytic decomposition eliminating the need for open flames, additional fuel, or complex infrastructure.
While EO remains indispensable as a sterilizing agent and chemical precursor, its inherent toxicity necessitates proactive mitigation strategies. The implementation of technologies such as SteriSpace enables a strategic transition from passive containment to active elimination redefining air purification not merely as pollution control, but as comprehensive detoxification achieved with precision, sustainability, and operational efficiency.
As environmental agencies intensify monitoring of airborne toxicants, this system offers an agile solution enhancing air quality in agriculture, industry, and beyond. The path forward lies not just in identifying pollution sources but in deploying targeted technologies that redefine clean air as a feasible, affordable standard.
