Scientific Research

Numerous official studies carried out internationally have shown that viruses and bacteria, including Coronavirus, are widely present in the aerosol/droplets generated during the use of the toilet.


Research has shown that aerosol released from toilet remains suspen-ded in the air for many minutes to hours, becoming a source of SARS-CoV-2 spread when inhaled by an healthcare professional or, in any case, by a subsequent user. Toilet use also generates aerosolized viral and bacterial particles that can land on nearby surfaces increasing the risk of contamination
