The VaPURE™ technology Mold Solutions SoCal uses has been studied by the U.S. Army Corps of Engineers, and its chemistry, vapor peracetic acid, has been tested in independent GLP-compliant laboratories. Each paper below links to the full PDF.
The three documents are a field study by the U.S. Army Corps of Engineers, a compilation of GLP-compliant laboratory reports, and a technical white paper written by another Pure Maintenance licensee.
A six-month evaluation by the Army's Engineer Research and Development Center of the VaPURE™ application system in two buildings at Fort Campbell, Kentucky, measuring both initial efficacy and long-term recurrence.
The report starts from the fact that mold is an ongoing problem on Army installations. A project team from Fort Campbell, the Engineer Research and Development Center's Construction Engineering Research Laboratory, and Pure Maintenance LLC treated two vacant buildings at Fort Campbell, a dining facility and a barracks administration section. The team sampled the air and surfaces before treatment and again over the following six months.
Six months after treatment, total indoor spore counts were more than 95% lower in both buildings, while the outdoor counts used as a background rose over the same period. The authors also note that each building took 5 to 6 hours to treat, including the sampling.

Independent, GLP-compliant laboratory tests of vapor peracetic acid (VPA), the chemistry behind the VaPURE™ process, against a laboratory panel of microbial targets that includes mold.
Good Laboratory Practice is the methodological standard regulators apply to safety and efficacy studies. This compilation gathers a series of independent GLP-compliant lab tests of vapor peracetic acid (VPA), the chemistry behind the VaPURE™ treatment we use in your home.
The headline finding is a Log‑6+ reduction, meaning the chemistry was shown effective against more than 99.9999% of the panel of mold, bacterial, and viral targets in laboratory testing.
The compilation is hosted publicly and includes the methodology, organisms tested, and individual lab reports.
The author calls particle size, vapor phase change, and dwell time the three “magic bullets” of the process, and explains how each one helps the treatment behave like a gas.
The paper explains why the treatment behaves like a gas once it is in the air, using three variables that work together.
Particle size. Pure Maintenance's patented equipment makes droplets of 7.5μm or smaller, about 1/9th the width of a 70μm human hair. Droplets that small stay aloft.
Phase change. While the droplets hang in the air, the water in them evaporates. That raises the concentration of peracetic acid vapor and the vapor pressure in the treated space.
Dwell time. Because the droplets stay suspended for an extended time, the vapor has time to work. The paper lists HVAC systems, high corners, the undersides of furniture, and baseboards among the places it reaches.
