The reason that they work much better is that instead of targeting small target areas with a spray bottle and towel, when done properly, fogging blankets the entire area of a property in a very rapid amount of time, which includes hidden areas you cannot get to with disinfectant. Further, since fogging is semi-automated, covers a wide area, and should inactivate the airborne virus, it should allow higher sanitation efficacy, increased compliance, and better worker productivity.' (2) (1)Ī 2017 study of the virucidal activity of using a fogging machine with chlorine dioxide and hydrogen peroxide-based disinfectants against Human Norovirus found a significant advantage to fogging in that it can uniformly provide exposure to disinfectant throughout the room, covering even hard-to-reach surfaces. In 2014, even NASA started using and promoting these machines along with a particular disinfecting product.

Also, mold and environmental remediators like myself use foggers regularly in their business to kill and prevent toxic mold and other harmful microorganisms. Some machines require a specific hydrogen peroxide-based product.įor several decades, the medical industry has been utilizing these machines for sanitizing hospitals and sterilizing medical equipment. What I have found to be the most effective method to disinfect medium and large buildings is by using what is called a 'handheld fogger or fogging machine,' which can be characterized as dry fog systems or wet fog systems.Ī wet fog machine normally uses a chlorine dioxide or hydrogen peroxide-based product, and dry fog systems use a hydrogen peroxide-based disinfectant/sterilant for decontamination. Over the years, I have cleaned and disinfected many properties, both small and large. If you use just a spray bottle and towel, you will be guaranteed to miss many areas that could be harboring the coronavirus (Covid-19) or other harmful microorganisms. Disinfecting against Covid-19, however, refers to using certain products to kill pathogens on surfaces, thereby lowering the risk of spreading disease.

Still, this process does not kill germs but helps reduce their numbers and the risk of spreading infection. The CDC defines 'cleaning' as the removal of germs, dirt, and impurities from surfaces. Cleaning and disinfecting medium to large areas with accuracy and a high degree of killing unseen pathogens in hidden areas is challenging.
