A peer-reviewed clinical study published in JAMDA - The Journal of the American Medical Directors Association has demonstrated that Pyure's continuous air purification technology can significantly reduce respiratory and viral infections among elderly residents in long-term care facilities. The two-year study found a 48% reduction in infection rates, cutting the overall infection rate in half without any changes to staffing or resident routines.

Why it matters

Airborne infections remain a leading cause of illness, hospitalization, and mortality in long-term care facilities, so a solution that can materially reduce infection rates without adding operational burden represents a meaningful step forward for healthcare providers. This study provides strong real-world evidence that Pyure's hydroxyl-based air purification technology can improve health outcomes and quality of life for vulnerable elderly populations.

The details

The study, led by Dr. Yochai Levy of the Shmuel Harofeh Geriatric Center in Israel and co-authored by Prof. Itamar Grotto, a leading public health authority, found a 48% reduction in respiratory and viral infections among elderly residents using Pyure's continuous air purification system. The infection rate was cut in half, from 5.16 to 2.68 per 1,000 patient-days, with statistically significant results indicating less than a 0.1% chance the outcomes occurred by chance. No changes were made to staffing, workflows, or resident routines during the study period.

  • The two-year study was conducted from 2023 to 2025.

What they’re saying

“The publication of this study marks an important step forward in infection prevention. We now have strong real-world evidence showing that Pyure's active and dynamic hydroxyl-based continuous air purification technology can significantly reduce infection burden in one of the most vulnerable populations — without adding complexity to care delivery.”

— Mahyar Khosravi, Chief Executive Officer of The Pyure Company

What’s next

The study findings will likely lead to increased adoption of Pyure's air purification technology in long-term care facilities as a proven method to reduce respiratory and viral infections among elderly residents.

The takeaway

This peer-reviewed study provides compelling evidence that Pyure's hydroxyl-based air purification system can significantly improve health outcomes for vulnerable elderly populations in long-term care settings, offering a valuable tool to combat airborne infections without adding operational complexity for healthcare providers.
