The function and Purpose of Ozone in Covid-19 Sanitisation

The novel coronavirus has presented businesses with an unfamiliar threat, recourse to traditional methods of sanitisation and cleaning appear to be of assistance to the re-opening of industries, but in reality will prove, laborious, costly, and unsustainable.

Ozone serves as a powerful oxidiser, offering a steriliser system that effectively eliminates micro-organisms. The use of ozone is well documented, notably in water treatment facilities where its efficacy is long-established. Kowalski et al note, ozone is a highly effective aerial sanitiser(1). Also, in contrast to UV sanitisation, ozone is effective throughout the whole area, disinfecting fabrics and contents within.

Ozone as an unstable gas, quickly reverts back to oxygen once the sanitisation process has ceased. No undesired residue is left on surfaces which may be present with traditional sanitisation methods. All that results, is a clean and sterilised work environment, including difficult and sensitive contents that would, with other methods, serve a challenge.
