Frequently asked questions

It is a molecule composed of three oxygen atoms linked together.

Ozone is produced in nature mainly through lightning, UV rays and other special chemical-physical processes.


It is unstable: it cannot be stocked; it must be produced by special generators and used directly on site.


It quickly kills all micro-organisms and rapidly turns into oxygen, leaving no traces or chemical residues.

  • high oxidizing power;

  • it is an unstable gas, decaying after a few minutes back to oxygen (O2);

  • does not leave any kind of trace or chemical residue;

  • it does not leave unpleasant odors or stains on the fabrics;

  • being heavier than air, it tends to accumulate downwards;

  • is able to inactivate and eliminate many polluting or harmful elements;

  • its life time is very short, it can not be stored; it must be produced and used immediately.

As soon as ozone comes in contact with organic matter, an oxidation reaction is triggered. Basically all living micro-organisms are killed, such as mites, bacteria, viruses, molds and fungi.  The molecules of odors are oxidized and transformed into other harmless molecules, thus eliminating any form of bad smell.

Since ozone is heavier than air, it can penetrate into the fibers of the fabrics (mattresses, sofas, armchairs, carpets, carpets, car interiors). In this way it reaches and eliminates any microorganism and malodorous substance found even in the most difficult to reach points, impossible to thoroughly sanitize with a classic wash, however meticulous and accurate.

  • Does not require the use of industrial chemicals

  • Ozone does not mask odors, it eliminates them

  • Ecological – does not pollute the environment and leaves no residue

  • It is an automatic system

  • Eliminates VOC toxins – volatile organic compounds

  • Can be used (recommended) where food is kept

  • Prevents the spread of disease and infections

  • Provides clean, oxygenated and disinfected environments

  • Competitive running costs

  • Powerful and optimal sanitation of the environment through the saturation of the environment itself

  • It does not require airing the environment after use

Many studies say that disinfection and sanitization by ozone is more than 2,000 times more effective than any type of traditional sanitization, totally eliminating all possibility of infection and allergy, as well as eradicating molds, germs, mites and micro-bacterial charges harmful to health.

The ozone sanitization system is a completely eco-friendly cleaning method, leaving no chemical residue behind it, and has been defined as a “GRAS” safe agent by the F.D.A, the US Food and Drug Administration.

In Italy, the Ministry of Health, with protocol No. 24482 of 31/07/1996, recognized ozone disinfection system as a natural method for the sterilization of environments contaminated by bacteria, viruses, spores, etc. and infested with mites and insects.


To summarize, an ozone sanitization treatment:

  • Eliminates bacteria, viruses, mites, molds, fungi, spores and any type of parasite in an ecological and natural way;

  • Eliminates unpleasant smells;

  • Leaves no residual chemical traces, but turns into pure oxygen after use, so it is also environmentally friendly;

  • Cleans and sanitizes thoroughly, even the least accessible cracks, every surface with which it comes into contact;

  • Can be used to sanitize mattresses, sofas, armchairs, carpets, carpets, cars, rooms, etc.;

  • Is a procedure recognized by the Italian Ministry of Health.

The certificate certifies that a particular environment has been disinfected to protect both the supplier and the user of a specific service or product.

  • In the hotel sector, for example, the certificate can
    be a valid tool in the hands of the hotelier, who can
    guarantee complete disinfection of a room, or of a specific environment, within his/her own structure, ensuring a high level of service.


  • In the health sector (hospital), the certification can be inserted in the discharge chart following a period of hospitalization. In addition to minimizing the risk of infections, the hospital has an additional tool at its disposal in case of disputes.
