EFFECTIVENESS AND EFFICIENCY

Fogging is currently one of the most effective methods of disinfection in the fight against COVID-19 disease caused by coronavirus 2019-nCoV, in addition, it fights bacteria and fungi.

This method was most widely used in the Chinese province of Wuhan and contributed significantly to combating the coronavirus epidemic.
The effectiveness of fogging is very high, because the drops created during spraying are very small and thus can penetrate into many places inaccessible during standard disinfection methods. In addition, during fogging, entire surfaces, both horizontal, vertical and irregularly shaped, are evenly covered with a thin layer of disinfectant, what is practically unobtainable during standard cleaning or spraying surfaces with disinfectants. Thanks to the fine particle cloud created in the fogging device, the disinfectant reaches not only visible surfaces, but almost every place in the disinfected room.
The fogging technique requires the use of a smaller amount of disinfectant at the same time greater efficiency compared to traditional methods such as washing or spraying and thus the costs of fogging are lower than conventional disinfection.

TECHNIQUE
Depending on the specifics of the layout of the rooms, their purpose, periods of use and the disinfecting substance used for fogging, we use cold fog generators or thermal foggers.
Cold fogging is usually done with ULV generators that produce droplets between 5 and 30 microns forming a thick fog. Cold fog generators are free of hot flue gas, which is a big advantage and is important when using high temperature sensitive biocides. In addition, it is used in rooms where, due to their intended use, exhaust gas foggers cannot be used.
During thermal fogging, the working liquid evaporates under the influence of high temperature and condenses when in contact with the colder atmosphere of the room. A mist with a drop diameter of 0.5 to 10 microns is formed and can stay in the air much longer than a cold mist. It enables longer contact of the preparation with the organism to be fought, which at the same time means the possibility of a significant reduction in the amount of the working liquid administered, and reduces the time of the procedure.
A common addition to the working solution of a disinfectant is propylene glycol, a substance commonly used in the chemical, food and pharmaceutical industries that can come into contact with food. Propylene glycol is also used to produce artificial smoke or fog, e.g. during fire training or theater production.
To make it easier to imagine what drop sizes we describe, they can be compared to commonly known values:
hair thickness 90 microns,
drop of deodorant 50 microns,
drop of cold fogging 20 microns,
drop of thermal fogging 5 microns

APPROVALS
The disinfectants we use have a National Institute of Hygiene certificate, a certificate of the Office for Registration of Medicinal Products, Medical Devices and Biocidal Products, and meet the EN 14476 standards in the medical area for strains of non-enveloped (harder to control) and enveloped viruses and have proven effectiveness in eliminating bacteria, viruses, fungi and other microorganisms. These agents do not contain toxic substances and are safe for the health of people staying in the disinfected room. Meets the requirements of REACH (EC) No. 1907/2006.
