The VaPURE™ technology Pure Maintenance of Ohio uses has been studied by the U.S. Army Corps of Engineers and tested in independent GLP-compliant laboratories. Below are the three papers behind the treatment we use in your home, each with a link to the PDF.
A field test by the U.S. Army Corps of Engineers, a set of GLP-compliant laboratory reports, and a Pure Maintenance white paper on 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 is a reduction in spore counts of more than 95% that still held at the six-month check, in buildings people were living in, without retreatment.
The full ERDC technical report is hosted publicly by the U.S. Army Corps of Engineers digital library.
A compiled set of GLP-compliant independent laboratory tests of the vapor peracetic acid (VPA) treatment, including tests against mold. VPA is the chemistry behind the VaPURE™ process.
Good Laboratory Practice is the methodology standard regulators use for safety and efficacy studies. This compilation gathers a series of independent GLP-compliant lab tests of vapor peracetic acid, the chemistry in the VaPURE™ treatment we use in your home.
Each report sets out the lab's method and the measured reduction, so you can read the results as the labs wrote them.
The compilation is hosted publicly as a single PDF.
A technical explainer of the three variables that make the treatment behave like a gas: particle size, vapor phase change and dwell time.
This paper explains the physics behind the treatment. Three variables, working together, make it 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, which is small enough to stay suspended and travel where air goes: wall cavities, ductwork, behind cabinets and into porous building materials.
Phase change. The treatment is delivered as a liquid that flashes to vapor on application, spreading through the air in the structure instead of coating only the surfaces a sprayer can hit.
Dwell time. The vapor stays suspended long enough to treat the mold it contacts.
An inspection with air samples shows what the numbers look like in your own home. Call the office or book online to set one up.
