What is Toilet Plume and how can eFlow-Constant Airflow Regulators keep bathrooms from getting people sick ?

What is Toilet Plume? Toilet plume occurs when the force of flushing the toilet sprays microscopic particles into the air. A study conducted by The CDC demonstrated that potentially infectious aerosols may be produced in substantial quantities during flushing. Aerosolization can continue through multiple flushes and may expose subsequent toilet users. Some of the aerosols desiccate to become droplet nuclei and remain adrift in the air currents. Research suggests that toilet plume could play a contributory role in the transmission of...
