Evaluation of the virucidal effectiveness (SARS-CoV2) of dry steam
Laboratory Eurofins Biolab - Vimodrone (MI) – Italy

Considering that:

  • The SARS-CoV2 virus - according to the published information - has similar heat-sensitive properties to other Coronaviruses;
  • Thermosensitive viruses are completely deactivated in a few seconds at very high temperatures, for example from 150° to 160°C due to the heat and the deactivation speed for each log is minimal, quantifiable as about 0.1 seconds;
  • Coronaviruses are completely deactivated within one minute at 80°C from the heat generated by dry steam and the log inactivation speed is approximately 10 seconds;
  • The viral load of Coronavirus can be partially reduced within one minute at 65°C from the heat generated from dry steam;

It can be said that the steam treatment of Polti equipment must be considered effective in completely deactivating the SARS-CoV2 virus at a temperature of 80°C or higher. With the very high temperatures reached by the Polti Vaporetto models compatible and combined with the Polti Sani System Gun accessory, deactivation is effective in very short exposure times (a few seconds).

Acaricidal effectiveness
Cambridge University – Lyon Dermatalogical Hospital

Two prestigious institutions - the Cambridge University and Lyon Dermatological Hospital - have subjected a Polti steam cleaner to dierent eectiveness tests.

The experiment was based on the comparison between the Polti steam cleaner and normal vacuum cleaners and their ability to eliminate dust and scabies mites.

  • Cambridge University examined two carpets and two mattresses, artificially contaminated with live mites. A carpet and mattress were cleaned with a traditional vacuum cleaner, the other carpet and the other mattress with the Polti steam cleaner that eliminated: 97% of the mites from the carpet and 98% from the mattress, with an 86% decrease in allergens.
    The traditional vacuum cleaner, however, eliminated only 57% of mites and 46% of allergens.
  • Lyon dermatological Hospital has tested the effects of the Polti steam cleaner against scabies mites, which can be present on bedding and environments surrounding infected people.
    The mites were eliminated after only 5 seconds of exposure to the powerful steam jet. Polti Vaporetto e Polti Unico: acaricidal effectiveness

Polti Vaporetto, Polti Vaporetto Lecoaspira e Polti Unico: the natural way to eliminate mites and allergens. These results confirm that the steam generated by these Polti steam cleaners can not only reduce the number of live mites, but can also decrease the allergens produced by them, providing an extraordinary decontaminating action. All for the benefit of our health and the prevention of allergies.
These results have been further confirmed by the British Allergy Foundation, which awarded both Polti Vaporetto and Polti Vaporetto Lecoaspira its Seal of Approval as products effective in the elimination of mites.
