The VaPURE™ technology PureAire Technology uses has been studied by the U.S. Army Corps of Engineers and tested in independent GLP-compliant laboratories. Below are the three papers that underpin the work we do in your home, with a link to each paper.
Three independent works document the technology PureAire Technology deploys: a multi-month field test by the U.S. Army Corps of Engineers, a compilation of GLP-compliant independent laboratory efficacy reports, and a technical white paper explaining why the vapor behaves like a gas.

ERDC/CERL TR-18-17, August 2018. A six-month evaluation by the Army's Engineer Research and Development Center of the two-step vapor process on two occupied buildings at Fort Campbell, Kentucky, sampling before treatment, immediately after, and again at one, three and six months.
The U.S. Army needed a way to remediate mold inside occupied barracks without removing structural materials or relocating soldiers. The Engineer Research and Development Center evaluated the vapor-based application system across two buildings and compared spore counts before treatment, immediately after, and again six months later.
The result that matters is durability, not day one. In Bldg. 2261 the weighted indoor spore count fell from 64,126 spores/m³ before treatment to 3,067 spores/m³ six months later, a 95.21% reduction, while the outdoor background count over the same period rose. In Bldg. 6733 the indoor count fell from 556,057 to 3,044 spores/m³, a 99.45% reduction. The report's own summary: the treatment kept mold below background levels across the six-month period.
That is the same standard we work to on your property: mold levels inside the treated space at or below the outdoor reference sample, measured by air sample and analyzed by an accredited third-party lab.

A compiled set of GLP-compliant independent laboratory tests of vapor peracetic acid (VPA), the chemistry behind the VaPURE™ process, run against a laboratory panel of microbial targets including mold.
"Good Laboratory Practice" is the methodological standard regulators apply to safety and efficacy studies, the same rigor used to evaluate pharmaceuticals. This compilation aggregates a series of independent GLP-compliant lab tests of vapor peracetic acid (VPA), the chemistry that powers the VaPURE™ treatment we deploy in your home.
The headline finding is a Log‑6 reduction in the laboratory panel. Log‑6 is the threshold a chemistry has to clear to be classified as a sterilant; most consumer disinfectants are tested to Log-3. That is a laboratory result for the chemistry, under controlled conditions, and it is not a claim about what happens in any particular building. What happens in your property is settled by the air samples we take before and after.
The compilation is hosted publicly and includes the methodology, organisms tested, and individual lab reports.
A technical explainer of the three variables (7.5μm particle size, vapor phase change and dwell time) that make the treatment behave like a gas and reach where surface cleaning never does.
This paper breaks down the physics of why VaPURE™ outperforms conventional remediation. Three variables, working together, are what make the treatment behave like a gas rather than a liquid: particle size, phase change, and dwell time.
Particle size. At 7.5μm, each vapor droplet is roughly a ninth the diameter of a human hair, which the paper puts at 70μm. A mold spore measures 12 to 30μm, so anywhere a spore got in, the vapor can follow: wall cavities, ductwork, behind cabinets, into porous building materials.
Phase change. The treatment is delivered as a liquid that flashes to vapor on application, occupying the full air volume of the structure rather than coating only the surfaces a sprayer can hit.
Dwell time. The droplet is dry and light enough to stay aloft while the distilled water in it evaporates, which raises the peracetic acid concentration to the 30 to 40 ppm range and holds it there long enough to denature mold proteins on contact, treating the spore rather than dislodging it.
Together they explain how a single in-place treatment reaches the parts of a property where mold actually lives, and which a scrub-and-cut crew can only get to by tearing structural materials out.
