A LifeAire Systems white paper examining the critical impact of airborne pathogens on healthcare safety and economics. The paper reviews the $28.4 billion annual cost of healthcare-associated infections in the United States, the limitations of HEPA filtration as a capture-only strategy that does not neutralize pathogens or eliminate VOCs, and the paradigm shift represented by ASHRAE 241: Control of Infectious Aerosols — which establishes new standards for single-pass pathogen inactivation that LifeAire's technology meets and surpasses. The paper presents comparative environmental data showing 1,778 cfu/m3 viable biological pathogens and 1,372 ppb chemical contamination in HEPA-only clinical environments versus less than 1 cfu/m3 biological and less than 100 ppb chemical in HEPA plus LifeAire-purified environments. Includes study design details from the St. Luke's Allentown 12-month hospital study, long-term care outcomes, and ASHRAE publication references. Published by LifeAire Systems, 2026.
A LifeAire Systems case summary presenting key outcomes from the 15-month IRB-approved study of LifeAire's advanced air purification technology in a memory support long-term care facility. The study compared a LifeAire-protected floor with a HEPA-only control floor in the same facility. Documented outcomes in the LifeAire-protected unit included an 89.1% reduction in airborne pathogens, an 88.9% reduction in surface pathogens, a 39.6% reduction in facility-acquired infections, and a 47% reduction in staff call-outs. The findings demonstrate that continuous air purification delivers measurable improvements in resident health, staff wellbeing, and facility economics in long-term care and memory support environments. The underlying peer-reviewed data was published in The Journals of Gerontology: Series A, 2023. Published by LifeAire Systems, January 2026.
A LifeAire Systems case summary presenting the financial and clinical outcomes from a 12-month air purification study conducted at St. Luke's University Health Network in Allentown, Pennsylvania. LifeAire's advanced air purification system was installed in a 14-room medical-surgical unit and compared against a matched HEPA-only control unit across 8,255 patients. Documented outcomes included a 99.99% reduction in viable airborne pathogens, a 97% reduction in surface pathogens, a 39.5% reduction in patient length of stay, a trending reduction in hospital-acquired infections, and $2.3 million in total documented savings in a single year from a system costing less than $125,000 fully installed. The underlying peer-reviewed data was published in the journal Surgery, September 2020. Published by LifeAire Systems, January 2026.
Independent third-party testing data documenting the volatile organic compound removal performance of the LifeAire Aire~IRMU In-Room Modular Air Purification Unit. The Aire~IRMU delivers LifeAire's proven multi-stage purification technology — including molecular media VOC neutralization, UV pathogen kill, and HEPA filtration — in a compact, plug-and-play format requiring no HVAC integration. This testing data validates the VOC remediation capability of the Aire~IRMU for facilities and clinical environments where in-duct systems are not practical, including patient rooms, clinic spaces, senior living environments, and IVF laboratories.

A peer-reviewed poster abstract presented at the ASRM Annual Scientific Congress, October 2024, examining isopropyl alcohol infiltration as a persistent airborne toxin in modern IVF laboratories. Isopropyl alcohol is widely used as a disinfectant in clinical and laboratory environments and generates airborne VOC contamination that can infiltrate IVF incubator environments and culture media. The study reviews the persistence of IPA in the IVF laboratory air environment and its potential impact on embryo culture conditions and outcomes, contributing to the growing evidence base for maintaining VOC levels well below current clinical thresholds in fertility medicine. Presented at ASRM Annual Scientific Congress, October 2024. Authors: Orsolini, M.; Schenkman, E.; Russack, J.; Huynh, H.; Schust, D.; Raburn, D.; Worrilow, K.C.; Fox, J.T.
A peer-reviewed narrative review published in F&S Reviews, Volume 6, Issue 1, June 2025, examining the role of environmental toxicology in impairing in vivo fertility and gamete quality prior to IVF treatment. The review evaluates how pre-IVF exposure to environmental contaminants — including heavy metals, per- and polyfluoroalkyl substances (PFAS), persistent organic pollutants, and airborne contaminants including VOCs — may impair gamete potential and downstream IVF success rates. The authors provide a comprehensive reference of toxicological exposures for IVF clinicians, drawing on in vitro, animal, and human correlative data to identify potential causative mechanisms and strengthen the case for routine patient toxicological risk assessment before IVF treatment. Published in F&S Reviews, Volume 6, Issue 1, June 2025. DOI: 10.1016/j.xfnr.2025.100090. Authors: Orsolini, M.; Russack, J.; Huynh, H.; Raburn, D.; Fox, J.; Schust, D.
A peer-reviewed study published in Applied In Vitro Toxicology, Volume 11, Issue 4, 2025, presenting kinetic models for predicting the transport of airborne volatile organic compounds into cell culture systems in highly sensitive in vitro processes and biopharmaceutical manufacturing facilities. Building on prior equilibrium partitioning modeling work, this study addresses a fundamental knowledge gap regarding the rate of VOC partitioning into cell cultures — critical for understanding how airborne contamination affects both IVF embryo culture outcomes and cell and gene therapy manufacturing processes. The models demonstrate how VOC transport rates from ambient air into culture media can be predicted and managed, with direct implications for air quality standards in IVF laboratories and biopharmaceutical cleanrooms.

A peer-reviewed poster abstract published in Fertility and Sterility, October 2024, examining the impact of low-level volatile organic compounds on embryo morphokinetics and development in murine preimplantation embryos. Current IVF guidelines recommend maintaining VOC levels between 400 and 800 ppb, yet this study presents emerging evidence that VOCs below that threshold can adversely affect specific metrics of embryogenesis. Using time-lapse analysis, the study assessed the impact of low-level VOC exposure on developmental timing across multiple embryo stages. The findings strengthen the scientific rationale for maintaining VOC concentrations well below current clinical thresholds in IVF laboratory environments.
