Margin and reputation protection

Reduce shrink.
Extend shelf life.

Every percentage point of shrink and every additional day of shelf life flows straight to your margin and reshapes route economics, claim loss ratios, and retailer leverage. Pür Plasma is independently validated to drive both at once across working perishables operations.

Surface and airborne fungal pressure reduction

Pür Plasma reduces the risk from various sources of bioburden amplification - HVAC, product movement, plant touching, employee movement.

Ethylene scrubbing

Pür Plasma is independently tested to continuously reduce to undetectable levels and operates continuously, scrubbing endogenous ethylene as ripening climacteric fruits emit it.

Speed and throughput that match real operational airflow.

Pür Plasma neutralizes pathogens up to 120x faster than PCO, Ionizers, and other leading technologies. It is proven to be the only effective solution that keeps up with real world air cycles in commercial spaces.

Chemical-free, residue-free, organic-compliant.

Pür Plasma complies with USDA National Certified Organic Standards, CARB-certified ozone emissions, and is UL 2998 certified ozone-free. It works around the clock without compromise.

One technology, deployable across the entire supply chain.

Pür Plasma operates continuously across every controlled-environment node a perishable touches. It can be put to work in spaces of any size and any type to reduce contamination handoff between stages.

Ripple effects

Hit the pathogens that fail compliance and trigger recalls.

Most "air sanitizing" tech is tested against generic surrogates (MS2 phage, Staph epidermidis) that say nothing about whether the system kills the species your state actually tests for. Pür Plasma's BSL-2 lab data is on the actual organisms, including all four California-listed Aspergillus species.

Botrytis Cinerea, Aspergillus, Fusarium, Powdery Mildew

In a multi-state commercial cultivation deployment, Pür Plasma reduced and maintained Botrytis by 81%, Aspergillus by 86%, Fusarium by 82%, and Powdery Mildew by 75%. It directly targets the pathogens that destroy yield and trigger automatic state test failures.

Salmonella, E. coli O157:H7, Listeria, Norovirus, Rhinovirus, Hepatitis A

BSL-2 lab testing on actual pathogens — not surrogates — confirms Pür Plasma achieves 99.9999% reductions of Salmonella, E. coli O157:H7, Listeria, Norovirus, Rhinovirus, and Hepatitis A. It protects against the organisms behind the recalls and foodborne illness outbreaks that can shut commercial operations down overnight.

“…For operators experiencing 10-15% batch failure rates, preventing just three 50-lb wholesale flower batches valued at roughly $1,200 per pound can offset the entire cost of a facility-wide air sanitation deployment in the first year, while reducing failure risk by as much as 90%.”

87% drop

airborne bioburden

In about three weeks, the worst offenders—Cladosporium, Aspergillus, Botrytis, Fusarium—had nowhere left to hide.

90%+ drop

The picture
of healthy air.

At any given time, there can be thousands of pathogens in a cubic meter of air. Pür Plasma provides a layer of protection resulting in healthier air and surfaces. Validated and tested, again and again.
