What is Dry Fog? The difference between Disinfectant Fog, Mist, and Spray Explained
Fog, Mist, and Spray all refer to the process of forming drops of water or fluid, varied by the difference of their particle diameter and density.
Droplet size can be measured in diameter and quantified in micrometers or microns (μm), which equates to one-thousandth of a millimeter.
Foggers emit a mixture of compressed air and fluid at low to medium pressure dispensed through an ultrasonic nozzle, dispersing the fluid into millions of these micronized droplets.

To provide a reference, the average human hair is approximately 100μm and a traditional aerosolized spray 150μm.
In comparison, fogging technology vaporizes disinfectant between 5-30μm providing the most delicate and efficient coverage of sanitizer to all surfaces and airspace. This treatment accumulates on surfaces with consistency to that of a 'morning dew,' a non drip like and uniform application.

At the 'dry fog' level of atomization, sanitizer is safe on fabrics, electronics, all hard surfaces, porous surfaces, and even paper products without rippling edges or dripping ink.
It is imperative your disinfectant fogging device has an adjustable micronization feature in order to treat delicate areas such as fabrics, electronics, and papers with a drier fog.
Misting (30-60 microns) and Spraying (60+ microns) with traditional devices such as pesticide sprayers or pump sprayers emit a wet consistency and present significant damage and health risks when dispensing disinfectant.
It is best to consult a professional when deciding which fogging device is best for your facility's sanitation needs.
DISINFX Disinfection Co.'s DIY Fogging Starter Kits include a range of true dry foggers, which safely atomize biodegradable disinfectant to sanitize your environments and airspace safely.
