The VaPURE™ technology Pure Maintenance of Pueblo uses has been studied by the U.S. Army Corps of Engineers and tested by an independent GLP-compliant laboratory. Below are the three papers that underpin the work we do in your home — with links to each PDF.
Three papers document the technology Pure Maintenance of Pueblo 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 Pure Maintenance technical white paper explaining why the vapor behaves like a gas.

A six-month evaluation by the Army's Engineer Research and Development Center of the VaPURE™ application system on two occupied buildings at Fort Campbell, Kentucky — measuring both initial efficacy and long-term recurrence.
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 headline result — a sustained 95%+ reduction in spore counts at the six-month mark — is what makes this study load-bearing. Day-one efficacy is common across mold treatments; verified durability is rare. The fact that those reductions held over half a year, in occupied buildings, without retreatment, is the part of the report that does the most work.

A compiled set of GLP-compliant independent laboratory tests of the vapor peracetic acid (VPA) treatment, run by Element in Eagan, Minnesota. VPA is the chemistry behind the Pure Maintenance of Pueblo VaPURE™ process.
"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.
For mold, the lab used Aspergillus niger, a species common in indoor air and on surfaces. Of the 22 test carriers spread through the treated room, none showed mold growth afterward.
A technical explainer of the three "magic-bullet" variables — 7.5μm particle size, vapor phase change, and dwell time — that make the treatment behave like a gas and reach places surface cleaning misses.
This paper breaks down the physics behind the VaPURE™ treatment. 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 1/9th the diameter of a human hair — small enough to stay suspended in air and drift into wall cavities, ductwork, the space behind cabinets, and porous building materials.
Phase change. The treatment is delivered as a liquid that flashes to vapor on application, dispersing through the treated space instead of coating only the surfaces a sprayer can hit.
Dwell time. The vapor remains in suspension long enough to denature mold proteins on contact — treating the spore rather than just dislodging it.
Together, these explain how a single in-place treatment can reach the hidden parts of a home where mold grows, which scrub-and-cut crews often reach only by tearing materials out.
