The WillowAir system is designed to capture and remove airborne contaminants, providing safer workplaces for employees. WillowAir effectively counters inhalation hazards of ground cannabis dust, respiratory irritants, airborne pathogens like Aspergillus, and overall health risks in cultivation environments. As a multifunctional system, WillowAir also combats the pervasive threat of airborne contaminants affecting plant quality, product safety, and regulatory compliance. By lowering exposure to microbial burden and cross-contamination, the system proactively maintains a clean environment throughout upstream processes.

Through collaboration, Willow's Science and Engineering teams developed the WillowAir, a MERV 13 rated system which captures contaminants as small as 0.3 microns. Each WillowAir unit efficiently filters 10,000 cubic feet, while powerful fans achieve five air changes per hour, ensuring necessary airflow for optimal growing conditions. With its adaptable installation options and scalable design, WillowAir is able to cover multiple operational needs, including grow rooms, post-harvest production, packaging areas, and office spaces. In this function, the system operates purely on air filtration without the need for UV, Ozone, or adaptive components.

“As a company committed to innovation and excellence, we are proud to be a part of the movement towards employee wellness in this industry. Consumer safety and product quality have always been our ethos, and WillowAir further supports our mission,” said Jill Ellsworth, founder and CEO of Willow Industries.
