The VaPURE™ technology Pure Maintenance Mold Removal 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 links to each PDF.
Three independent works document the technology Pure Maintenance Mold Removal 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. Skip ahead, or read each in order below.
Most mold treatment is a liquid problem pretending to be an air problem. The particle size is what separates the two approaches, and it decides where the treatment can and cannot reach.
Positive air pressure disperses the sterilant through the treated space as a vapor. The particles are roughly 7.5 microns across. Instead of settling on the first surface they meet, they rebound off it and keep moving, so the vapor disperses throughout the treated space and reaches surfaces, porous materials, soft furnishings and voids as it goes.
A mold spore measures between 12 and 30 microns. Anywhere a spore can travel, a 7.5 micron particle can follow. That is the whole argument, and it is why the process usually avoids demolition: there is no need to open a wall to reach what is inside it.
Surfaces are left dry. Nothing in the house gets wet.
Conventional remediation leans on containment, demolition, disposal and rebuild, with a ULV spray application over the top. The spray produces much larger droplets.
As those droplets travel they either condense on the nearest surface or burst in the air. Coverage ends up patchy and hard to predict, airborne spores go untreated, and the parts of the house the crew did not open up are not treated at all.
Which is why the containment approach has to tear out what it cannot reach.
The process runs in two passes with two different products. They do different jobs, and skipping the second one is what leaves a house exposed.
The first application is the sterilant vapor. It denatures the mold cells it reaches, on surfaces and in the air, turning them into inert matter. The active component is on the EPA’s Safer Chemical Ingredients List, and after treatment it breaks down into acetic acid, which is white vinegar, plus oxygen and water.
This is the pass that deals with the mold load the house already has.
The second application leaves a residual layer bonded to the surfaces it lands on. Under a microscope it is a field of spikes, a bed of nails at cell scale, and a spore that settles on it is disrupted rather than left to take hold.
The protectant is rated for roughly 90 days of residual protection. How long it is worth in practice depends on the moisture: fix the water problem and it has little to work against, leave a major leak running and 90 days is the realistic ceiling.
The VaPURE™ process is licensed from Pure Maintenance, which was founded in 2007 and reports treating more than 10,000 homes and businesses through its network across the country. Pure Maintenance Mold Removal is the Palm Beach County licensee, owned and run by Mike Pierce.
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 against mold, bacteria, and viral targets — the underlying chemistry behind the Pure Maintenance Mold Removal VaPURE™ process.
"Good Laboratory Practice" is the methodological standard regulators apply to safety and efficacy studies — the same rigour 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 — shown effective against more than 99.9999% of the panel of mold, bacterial, and viral targets tested in laboratory testing. Log-6 is the threshold a treatment must hit to be classified as a true sterilant. Most consumer disinfectants stop at Log-3 (99.9%); VaPURE™'s underlying chemistry clears the bar three orders of magnitude higher.
The compilation is hosted publicly and includes the methodology, organisms tested, and individual lab reports.
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 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 1/9th the diameter of a human hair — small enough to suspend in air and travel anywhere air goes: 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 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 90% of the home where mold actually lives and where scrub-and-cut crews can only reach by tearing structural materials out.
