Health

kill viruses in a large (even room-sized) airspace, even if they add germicidal lights, ionizers, and dual-level HEPA filtration. That does not mean germicidal lights can not kill some organisms IN CLOSE CONTACT, including bacteria (albeit unlikely most viruses at all or at least to safe levels). They (germicidal lighting) ARE used in many BL1-3 laboratories to supplement other protective features, including negative pressure, ventilation hoods, and obviously personal protective gear, but everything about these settings is controlled, including all aspects of ventilation, airflow, air evacuation and air turn-over.

These HEPA filtration units were designed (and do work well) to assist with reducing air-borne allergens that stimulate indoor allergies/asthma and in this aspect, CAN improve/protect health.
