FIELD: disinfectology; sanitation.

SUBSTANCE: group of inventions relates to the field of disinfectology and sanitation; it is designed for providing for aseptic conditions. The clean premise contains a system of heating, ventilation and air conditioning (HVAC), which provides for gaseous diluted hydrogen peroxide (hereinafter – DHP) at a concentration of at least 0.05 parts per million (ppm) and up to 1.0 ppm. The specified DHP is non-hydrated and does not contain plasma particles or organic substances, while it contains at least 0.015 ozone parts per million (ppm). The clean premise corresponds to at least 8 class premises requirements according to ISO 14644. In other embodiments, methods for preventing, reducing and eliminating contamination of the clean premise with microorganisms are provided, as well as method for reducing organic compounds in the clean premise, method for decreasing the level of volatile organic compounds in the clean premise, method for providing the specified clean premise with gaseous DHP at a concentration of at least 0.05 parts per million (ppm), as well as method for reducing contamination caused by organic substance adsorption during silicon plate production.

EFFECT: use of the group of inventions allows increasing the cleanliness with simultaneous reducing or eliminating microorganisms, such as bacteria, fungi, molds and viruses.
