LifeAire Systems protected memory support floor over 15 months and delivered 39.6% reduction in facility-acquired infections

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.

The clinical and environmental effects of an advanced air purification technology in multiple healthcare settings

A peer-reviewed study published in Science and Technology for the Built Environment examining the clinical and environmental effects of LifeAire’s advanced air purification technology across multiple healthcare settings — an acute care hospital and a long-term care facility. The study synthesizes environmental and clinical outcome data from both settings, demonstrating that LifeAire’s multi-stage system, designed to inactivate the genetic material of all airborne pathogens and remediate volatile organic compounds, produced consistent, measurable improvements across both facility types. Originally presented at the 2022 ASHRAE Annual Conference in Toronto. Published in Science and Technology for the Built Environment, Volume 29, Issue 9, October 2023. DOI: 10.1080/23744731.2023.2266349. Authors: Urrutia, A.R.; Stawicki, S.P.; Kimble, C.N.; Worrilow, K.C.

Clinical and Economic Outcomes from the Installation of an Advanced Air Purification Technology in a Long Term Care Facility

A peer-reviewed short commentary published in the Journal of Gerontology and Geriatric Medicine examining the clinical and economic outcomes of LifeAire’s advanced air purification technology in a long-term care facility over 15 months. The study compared LifeAire’s multi-stage system — combining VOC filtration, high-dose UV germicidal irradiation, and HEPA filtration — against standard HEPA filtration in a memory support unit. Documented outcomes included a 98.83% reduction in airborne pathogens, an 89.88% reduction in VOC levels, a 39.6% reduction in facility-acquired infections, and a 47% reduction in staff call-outs. The findings demonstrate meaningful improvements in resident wellness, safety, and facility economics. Published in Journal of Gerontology and Geriatric Medicine, July 2023.

The Effects of an Advanced Air Purification Technology on Environmental and Clinical Outcomes in a Long-Term Care Facility

A peer-reviewed, IRB-approved study examining the impact of LifeAire’s advanced air purification technology on environmental and clinical outcomes in a long-term care memory support facility over a 15-month period. The study compared a LifeAire-protected unit with a HEPA-only control unit on the same floor, measuring airborne and surface pathogen burden, facility-acquired infection rates, and staff absenteeism. 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 confirm that advanced air purification delivers measurable improvements in both clinical outcomes and operational performance in long-term care environments.

The Positive Impact of a Novel Air Purification Technology on Environmental and Clinical Outcomes

A peer-reviewed conference abstract examining the impact of LifeAire’s advanced air purification technology on environmental and clinical outcomes in a long-term care facility. The study deployed LifeAire’s system in a memory support unit and compared environmental and clinical metrics against a HEPA-only control unit on the same floor. The technology, designed to destroy the DNA and RNA of all bacteria, fungi, and viruses on a single pass while also remediating volatile organic compounds, produced measurable improvements in airborne and surface pathogen burden, facility-acquired infection rates, and staff absenteeism. Published in Innovation in Aging, Volume 5, Supplement 1, December 2021. Presented at the Gerontological Society of America Annual Meeting.

The Economic and Workforce Implications of Facility Acquired Infections

A conference presentation by Dr. Kathryn C. Worrilow, Founder and Chief Scientific Officer of LifeAire Systems, delivered at the LeadingAge Fall Financial Conference. The presentation examines the economic and workforce implications of facility-acquired infections in long-term care environments, addressing the financial burden of HAIs on facility operations, the impact of staff absenteeism driven by airborne pathogen exposure, and the return on investment case for advanced air purification as a proactive infection control strategy. Drawing on LifeAire’s peer-reviewed clinical evidence from long-term care settings — including a 39.6% reduction in facility-acquired infections and a 47% reduction in staff call-outs — the presentation makes the financial and operational case for comprehensive airborne pathogen remediation in senior living and memory care environments.

Reduced FAIs & Staff Call-Outs, A 15-Month Study

A conference presentation delivered at the 2021 NADSA National Conference reporting preliminary findings from a 15-month IRB-approved study of LifeAire’s advanced air purification technology in a long-term care memory support facility. The study compared a LifeAire-protected unit with a HEPA-only control unit on the same floor, measuring airborne and surface pathogen burden, facility-acquired infection rates, and staff absenteeism over the full study period. Results demonstrated significant reductions in facility-acquired infections and staff call-outs in the LifeAire-protected unit. This conference presentation preceded the full peer-reviewed publication of the study’s findings in The Journals of Gerontology: Series A (2023) and in the Journal of Gerontology and Geriatric Medicine (2023).
