What Is Fogging Disinfection, And Where Is It Used?

Fri 18 Feb, 2022


Fogging disinfection is a widely accepted technology in the realm of sanitising. It goes by several names, including disinfectant barriers, residual sanitising, and antimicrobial protection.

This article discusses what fogging disinfection is and where it is used.

What is fogging disinfection?

Fogging disinfection is a type of sanitization involving the use of vaporised disinfectant chemicals to sanitise all surfaces that the vapour comes in contact with.

In other words, it's like spraying your environment with disinfectant; but with a more intensive strategy. The chemical and water particles react quickly and dry within minutes.

Fogging disinfection equipment

Fogging machines are used in different ways and for a variety of purposes. For example, you can use these machines for humidification, pest control, mould treatment, odour control, and sanitization.

Here are the basic types of equipment you need for fogging disinfection:

Fogging disinfection machine

A ceiling air conditioner works the same as other conditioners. The only difference is that it's hung up in the ceiling. So cleaning it is the same as cleaning any other AC.

Power it off, dismantle it and clean the filters, coils, fins and vents separately. When they are cleaned and dried, you put them back in and power the AC again.

Thermal fogging machine

Thermal foggers are named so because they have a heated coil within a metal tube, causing the liquid disinfectant to vaporise.

This vapour (composed of several droplets) is then propelled out in a patent cloud. Thermal foggers get their heat from either electricity or propane.

How to clean a cassette air conditioner?

Ultra-low volume foggers, or cold foggers, do not use heat. Instead, they generate fog with pressure, using one of two ways:

a. The disinfectant solution is pumped through a high-pressure nozzle, or

b. The solution is slowly sent through a whirling of high-speed air.

The pressure divides the liquid into tiny droplets, which then sprays out as a fog that isn't very visible.

ULV fogging machines are usually powered by batteries, but some use gasoline.

Operators can modify the size of the droplets that the ULV foggers generate, allowing for different uses.

The lack of heat (which also means the absence of fire risk) makes ULV foggers a safe choice for indoor use.

Fogging disinfection liquid

A fogging disinfection liquid may contain different components. However, fogging is most effective when used with chemicals such as:

  • Quaternary ammonium
  • Liquid air
  • Glycerin based fog
  • Hydrogen peroxide

Does fogging disinfection work?

Yes, fogging disinfection is effective, generally speaking. However, improper application of the disinfectant can lead to a false sense of security.

It can also cause a rise in health hazards and may not effectively reduce the risk of infections. For optimum effectiveness, clean your surfaces with soap and water before spraying them with disinfectants. This is because dirty surfaces can make the fogging ineffective.

Is fumigation effective against coronavirus disease?

Yes, fumigation or 'disinfectant fogging' can be effective against coronavirus disease. However, several factors affect its efficacy.

Specifically, using antiviral disinfectant for your fumigation can reduce your risks of getting infected. This includes cleaning and disinfecting surfaces and objects that people frequently touch.

Is it recommended to fumigate outdoor surfaces during the COVID-19 pandemic?

Large-scale fumigation in areas like streets or an open marketplace for the COVID-19 virus or other viruses is not recommended.

This is because streets and sidewalks are not considered routes of infection for COVID-19.

Benefits of fogging disinfection

The benefits of fogging are beyond just disinfecting the surfaces in your home, and this may surprise you.

Fogging disinfection can improve the quality of your environment, and hence, have a positive impact on your health.

It kills germs, bacteria, and viruses

Fogging your environment means you are killing germs, bacteria, and viruses that may be present in hard to reach areas.

Disinfectant fogging after your environment has been exposed to an airborne disease can prevent the spread of illnesses.

It kills allergens, fungi, and mould

Mould and fungi in your home may trigger allergies. Spores from fungi and mould can prolong allergy season and worsen respiratory issues like asthma.

Disinfecting your home can kill allergens, fungi spores, and mould spores. Try disinfecting your surroundings if your allergies seem to be staying on even after the end of allergy season.


Fogging disinfectant vapour can help eliminate certain odours and leave your surroundings smelling fresh.

Fogging can clear out garbage, food, and tobacco smoke odour. Therefore, when you refresh your home with fogging disinfectant, it's a win-win situation.


Is fogging safe?

Overall, fogging your environment can provide you with the peace of mind that you are protected from potentially harmful microorganisms. However, because fogging involves chemicals, here are some safety precautions to take:

  • Keep fogging away from ignition sources.
  • Tell neighbours, family members, and anyone else that may go into the premises so that they do not breathe in chemicals.
  • Leave the disinfected place immediately.
  • Try to air the treated area once the place has been infected.
  • Remove all children, toys, pets, and food from the disinfected area.
  • Please read the instructions on the products and follow them carefully.
  • Keep fogging disinfection equipment away from children.
  • Get the phone number of your local poison control centre in case of anything.
