Indoor air sterilization with ozone helps to effectively protect against viruses and bacteria because ozone as a gas can penetrate everywhere even in the most inaccessible places. As long as the necessary precautions are followed, it is absolutely safe! We have the portable air sterilizers O3 Port10 and the floor Ozon O3 Tower28. They neutralize mold, bacteria, viruses, parasites and bad smells. They give the air freshness, cleanliness and disinfection in just 1 hour. They cover surfaces from 140 m² to 360 m². With good ventilation, ozone is rapidly converted to oxygen leaving the area sterile and clean.
