Facilities without or with poorly dimensioned ventilation systems often struggle with maintaining a clean and healthy air, resulting in elevated concentration levels of air pollutants such as virus, bacteria, pollen, mold spores, VOC, and outdoor pollution. This situation raises discomfort or even long-term health issues among the persons living, working, or spending substantial time there. Hospitals, schools, conference centers, offices and gyms are example of facilities where this is not an uncommon situation. In facilities such as medicine rooms, hazardous drugs pollute the air, risking the lifespan and quality of the medications being compounded as well as the health of patients and staff. FS35 High Flow HEPA’s combination of highly efficient air cleaning and quiet operation can help resolve this air quality challenge without disturbing concentration, conversation, or sleep.
