Asked Questions

+ What is the WillowPure System?

The WillowPure system is a proprietary, patented machine that produces pure ozone gas for the purification and decontamination of cannabis flower and trim. The WillowPure system was designed to prevent and decontaminate mold, mildew, yeast, E. Coli, Salmonella, and Aspergillus. Time and concentration for each specific pathogen has been tested for accurate degradation.

+ What is ozone?

Ozone gas is triatomic oxygen (O3), a naturally occurring form of oxygen. The third oxygen atom makes the ozone molecule highly unstable, which is the key to its oxidizing power and its ability to kill a variety of pathogens, including yeast, mold, bacteria, Aspergillus, coliforms, E. Coli, and Salmonella. That instability is also what controls biological growth of unwanted organisms much faster and more effectively than traditional disinfectants like chlorine and hydrogen peroxide. 

One of ozone’s most positive characteristics is its natural ability to degrade back to oxygen. For this reason, ozone technology, rather than heat pasteurization, has become popular in agriculture and in various food and plant applications. Because it rapidly breaks back down into oxygen, ozone leaves no residue.

Ozone applications are recognized as safe and effective when applied properly, and are compliant with FDA, USDA, OSHA, NSF/ANSI Standard 50 and UL lab standards.

+ Is ozone hazardous?

Exposure to high levels of ozone can be hazardous. Thanks to WillowPure’s lock-and-seal system, no ozone is able to escape when in use. Once the machine has completed its cycle, the gas naturally degrades back to oxygen in approximately 10 minutes. There is also a destructing device inside every WillowPure system that pulls in any remaining ozone and immediately converts it back to oxygen. As a fail-safe, the safety lock will not disengage until the concentration inside the machine has reached safe levels.

Following FDA and OSHA measures, we recommend standard safety procedures when working with ozone, including the use of gloves as well as protective gear for the body, face, and eyes.

+ How much product will fit in each WillowPure system?

The WillowPure 5 system, designed for craft, boutique and medical grows, is capable of running 5 pounds of product per run.

The standard WillowPure 20 system has two racks, each with 17 shelves. In total, both racks can hold between 18 to 20 pounds of product when flower or trim is evenly dispersed on the shelf in a single layer. Applying multiple layers onto the racks is not recommended, as this can reduce needed airflow.

The high-capacity WillowPure 40 is double the size of our standard WillowPure. This machine has 4 racks (17 shelves on each rack) and holds 38 to 40 pounds per run.

The WillowPure 360 utilizes the new, single drum system and has a throughput of 45 - 105 lbs. / Day.

+ When should the WillowPure system be used?

The WillowPure system is designed to treat post-harvest flower. For best results, product should be cleaned with the WillowPure system just prior to packaging or conversion into edible ingredients. For greatest effectiveness and to reduce the risk of cross-contamination, it is also recommended that the product first be cured and dried in a clean—or even sterile—environment.

+ Can I market my product as WillowPure tested?

Cultivators and dispensaries are encouraged to use the WillowPure logo on any product that has been purified with our technology.  Any use of this symbol in connection with a retail product represents an assurance to consumers that the product is clean and safe from pathogens and microbials.

+ Will the WillowPure system degrade terpenes or lower potency?

The WillowPure system does not degrade overall terpenes and potency.

+ How does the WillowPure system affect a product’s smell?

A residual ozone smell will accompany the product immediately after it is extracted from the machine. This smell subsides in a few days as the process of residual ozone converts back to oxygen. Because the process does not degrade terpenes, the plant’s natural aroma remains intact.

+ Is the WillowPure system considered organic?

Yes. Ozone is approved for use on products labeled “organic.”

+ What are the power requirements?

All of the WillowPure systems can be plugged into a standard outlet.

The WillowPure 5 uses 120 VAC | 5 Amps.

The WillowPure 20 uses 120 VAC | 10 Amps.

The WillowPure 40 uses 120 VAC | 12 Amps.

The WillowPure 360 uses 120 VAC | 10 Amps.
