Through the use of a proprietary nozzle which produces an ultrasonic shock wave, the FogClean unit atomizes disinfectant into microscopic droplets resulting in an very dry fog. The tiny fog droplets can combine with airborne pathogens of like size through a phenomenon called agglomeration and remove the pathogens from the air. Additionally, the surface volume of the large number of droplets created, provides effective wide spread coverage of the area which is being treated using small amounts of disinfectant. This technology has been successfully employed by FogClean’s parent company for over 25 years.

There are two main reasons a smaller droplet size is desirable during the disinfecting process. First, the smaller the disinfectant droplets are, the better opportunity there is to agglomerate and neutralize / destroy liked sized pathogens on non-porous surfaces and in the air. Airborne pathogens would be repelled by disinfectant droplets that are much larger as shown below while FogClean droplets average 3.7 microns in size which enable them to agglomerate with similar sized pathogen droplets. Second, as droplet size decreases, the amount of surface area being treated increases using the same amount of solution. So a nozzle that creates a smaller droplet or fog will use less solution to cover a given area than a nozzle that sprays disinfectant.

Compressed air. All that is required for the operation of the FogClean unit is a connection to a source of compressed air. There are no batteries to replace/recharge or connection to an AC source. The nozzle used for small to medium applications requires 80 psi capable of outputting 3 SCFM, while the heavy duty application nozzle utilizes 7.5 SCFM.

Sanitizing is the process of reducing the bacteria on surfaces. Disinfecting is the process of destroying or inactivating both the bacterial and viruses identified on the products label (on hard non-porous surfaces.) The level of removal of contamination will depend on the product used. Most EPA approved sanitizers only have claims for bacteria while disinfectants have claims for both bacteria and viruses.

FogClean products can use any liquid or water soluble disinfectants. To check the characteristics of various types of disinfectants effective on Covid-19, the EPA has a list of approved disinfectants at https://www.epa.gov/pesticide-registration/list-n-disinfectants-use-against-sars-cov-2-covid-19. There are several plant based disinfectants that are also approved by the FDA and are safe for humans. These can typically be applied without using PPE and are safe for use around food. One such disinfectant can be found at https://giccllc.com/path-away.html

FogClean systems have been used for a wide range of commercial and industrial applications such as disinfecting office buildings, warehouses, gym facilities, medical offices, first responder vehicles, places of worship, and many others. The ease of portability, economical use of disinfectant, dry/wet adjustability to meet CDC requirements, and fog coverage area per minute greatly minimizes the time it takes to effectively disinfect a facility.

Dry Fog is described as droplets below 10um in size creating a fog that floats in the air without leaving appreciable moisture in the area. It will build the humidity inside the area, but not leave any residue on items inside the area being disinfected. Wet Fog will have droplets above 20um in size, leaving a residue on areas of interest. This could be used if the person disinfecting wants to leave a residue on touch surfaces or ensure more solution on touch surfaces versus areas of moisture sensitivity. Some disinfectants also call for wetting a surface with solution for a period of time to be effective. Be sure to review the product label of your disinfectant.
