Peer-Reviewed Senior Living Research
Senior living facilities need indoor air that feels clean, smells clean, and supports the people who live and woA 2026 peer-reviewed publication in the Journal of the American Medical Directors Association examined continuous hydroxyl radical air disinfection in a geriatric long-term care department. The study reported a 48% reduction in respiratory and viral infections, with the infection rate moving from 5.16 to 2.68 per 1,000 patient-days.
This page summarizes the published research for senior living and long-term care decision-makers. Awen Natural Air did not conduct the study. As a Pyure reseller, Awen uses the findings as one research source when helping East Central Florida facilities evaluate Pyure equipment for occupied spaces.

Published study title: Continuous Hydroxyl Radical Air Disinfection and Infection Outcomes in a Geriatric Long-Term Care Department: A Prospective Cohort Study
Why the Research Matters
Long-term care departments operate continuously. Residents remain in the building, care teams follow established routines and shared spaces cannot simply be taken offline whenever respiratory illness is a concern.
The study examined whether continuous hydroxyl radical air disinfection could serve as an additional environmental layer while the department remained operational and whether infection outcomes changed during the studied period.
This makes the research relevant to senior living decision-makers looking for evidence from an occupied care environment rather than only a laboratory test or short demonstration.
What the Study Evaluated
The study evaluated infection outcomes in a geriatric long-term care department using continuous hydroxyl radical air disinfection.
Pyure’s published summary reports that the research included an untreated control group and that staffing, workflows and resident routines were not changed during the study.
The measured outcome was reported as infections per 1,000 patient-days. This accounts for both the number of people observed and the length of time they were present.

This page is a research summary, not an installation protocol. Do not add equipment counts, placement diagrams, room dimensions or treatment specifications.
Reported Outcomes
| Reported Result | What It Refers To |
|---|---|
| 48% reported reduction | Respiratory and viral infections in the studied department |
| 5.16 to 2.68 | Reported infection rate per 1,000 patient-days |
| p < .001 | The publication reported a statistically significant result |
| No statistical reduction in control | Pyure reports no statistically significant reduction in the untreated control group |
| No workflow changes reported | Pyure reports no changes to staffing, workflows or resident routines |
NOTE: These outcomes are reported from a specific 2026 JAMDA study setting and Pyure’s published summary of that research. They should not be presented as a guarantee that another facility will experience the same result.
What the Findings Support
- A measurable research point for senior living decision-makers to review
- Evidence from an occupied geriatric long-term care environment
- Further evaluation of continuous hydroxyl treatment as a possible additional environmental layer
- A facility-specific discussion about priority spaces, placement and operational goals
- Consideration of whether the technology can complement established facility procedures
What the Findings Do Not Prove
- They do not guarantee a 48% reduction in another facility.
- They do not prove that every respiratory or viral infection can be prevented.
- They do not replace cleaning, ventilation, hand hygiene or infection-control procedures.
- They do not determine the correct equipment quantity or placement for another building.
- They are not results produced by Awen Natural Air or an Awen customer.
- They are not the same type of evidence as Awen’s Blackberry Test.
The responsible takeaway is narrower and more useful: the study reported a meaningful outcome in one geriatric long-term care setting. The findings give other facility teams a credible reason to investigate whether a properly assessed hydroxyl solution may fit their building.
Questions a Facility Team Should Ask
Before selecting equipment, a facility team should clarify:
- Which rooms or common areas should be evaluated first?
- What are the building’s room dimensions, airflow patterns and occupancy levels?
- Does the facility need equipment designed for occupied spaces?
- How would the equipment complement current cleaning, ventilation and infection-control procedures?
- Would a demonstration, rental, lease, purchase or phased rollout make the most sense?
- Which operational, clinical, ownership or compliance stakeholders need to review the decision?
Awen’s Role in East Central Florida
Awen Natural Air did not conduct the JAMDA study. Awen’s role is to help senior living and healthcare-adjacent facilities in Brevard County and East Central Florida review the available information, identify priority areas and determine whether Pyure equipment may be a practical fit for the building.
The conversation should begin with the facility, not a predetermined equipment sale. Room layout, airflow, occupancy, treatment goals and operating conditions should guide the next step.

Frequently Asked Questions
Did Awen Natural Air conduct this study?
No. The study was conducted by the listed research authors and published in JAMDA. Awen is summarizing the findings for facility decision-makers.
Was the study peer-reviewed?
Yes. The publication appears in the Journal of the American Medical Directors Association, Volume 27, Issue 5, Article 106148.
What does the reported 48% reduction refer to?
It refers to the reported reduction in respiratory and viral infections in the studied geriatric long-term care department. The reported rate moved from 5.16 to 2.68 per 1,000 patient-days.
Does the study guarantee the same outcome elsewhere?
No. Results may vary by building, population, airflow, equipment selection, placement and operating conditions.
How is this different from Awen’s Blackberry Test?
The Blackberry Test is Awen’s visual proof-of-concept and is not clinical research. The JAMDA publication reports infection outcomes from a geriatric long-term care setting. Keep these evidence types separate.
