Buyer's Guide to Fogging Machines




How does a fogging machine work?

The fogger uses pressure to create a fine mist (or fog) which is applied to the targeted area, the spray density typically being moderated by a manual valve to ensure the optimum effect. The fine fog can reach into corners and difficult areas and may also penetrate porous surfaces


Where can I buy strong or concentrated antiviral disinfectant for a fogging machine?

You can buy super concentrate, strong is not required, as long as the chemical components are effective to kill off the virus - The fogger uses pressure to create a fine mist (or fog) which is applied to the targeted area, the spray density typically being moderated by a manual valve to ensure the optimum effect. The fine fog can reach into corners and difficult areas and may also penetrate porous surfaces


How do I sanitise and disinfect a large room using an Infection Control Fogging Machine?

The best way to sanitise a large room quickly and completely is to use an appropriate size fogging machine, such as FO 500, which has a range of up to 10 metres and a variable switch to control the output of the antiviral sanitizing solution to maximise the coverage.


What area can I cover with an antiviral fogging machine and How long does it take to fog a room?

Most APT Fogging machines will cover a 1500 cubic metres room space in around 5-7 minutes.


How long do I have to remain out of a room before I can re-enter it safely after using a fogger machine?

We recommend 30 to 40 minutes after routine sanitising. However, rooms can be entered into around 20 minutes or less depending on atmospheric condition, heat, and ventilation.


How do I set up the chemical fogging machine to achieve the best micron size and coverage?

Generally the setting of the machine should be set around - ¼ to &frac12 of a turn or number 2-3 on the control switch. This provides droplets of around 30 microns which produces enough humidity to allow the antiviral disinfectant to fully cover the surfaces and sufficient contact time to allow the antiviral disinfectant to work. Atmospheric conditions influence drying times especially in hot summer.


“A good test is to first set up the fogging machine and use water this will allow you to get an accurate cover ratio and get used to the fogger. Spray the water solution through fogger machine into a room, above a table and check the level of coverage after allowing few minutes contact settlement. Then time how long it takes to dry off, it should be around 15 minutes. Adjust the chemical flow accordingly until satisfied on contact time/coverage."


What do I need to safely start fogging and sanitising with antiviral disinfectant?

You should have a full PPE safety pack; goggles, PPF3 mask, gloves, moisture resistant hooded coverall suit, this is included with most APT fogging starter packs.

Where you cannot purchase a coverall suit, you can use overalls/waterproof clothing and then put it through the washing machine.


What is the recommended procedure for my staff to carry out fogging?

When you purchase your starter packs from APT you will be provided with the full fogging procedure job method for carrying out disinfecting and sanitising.

It is recommended that you produce a full set of Rams H&S documents to comply with Risk Assessments protocols for you and your operatives. APT can produce generic Rams upon request.


What do you put in a disinfectant fogging machine?

We strongly advise that you use an antiviral disinfectant and sanitiser that has been tested against viruses and other harmful bacteria, we recommend APT Viro Kill, which is a Super Concentrated Disinfectant cleaner and sanitiser with a fast kill rate to fight against coronavirus.

Viro Kill is a powerful fast acting amphoteric terminal disinfectant is scientifically designed with a broad spectrum of activity and complies to BS EN14476, EN1276 & EN13697.

Viro Kill does not contain any harsh ingredients and can safely be used to treat and sanitise all hard surfaces and even most soft furnishings.

Viro Kill is food safe, so can be used in food manufacturing & processing plants.

Avoid using antiviral disinfectants that contain parasitic acid, hydrogen peroxide or sodium hypochlorite-based bleach disinfectants, these are very powerful, harsh chemicals and are not suitable for many internal surfaces. They can also affect machine performance and require extra safety precautions. They should only be used by a trained professional.


Do I need to turn off the air conditioning when fogging?



Can you use fogging machines for hospitals?

Yes, they, the hand held fogging machines are perfect for this purpose and all health care facilities, surgeries, dentists and clinics.

The Benefits of a Fogging Machine in Sanitisation

The Benefits of a Fogging Machine in Sanitisation

This year, the Covid-19 pandemic has placed the urgency of deep cleaning and sanitisation front and centre in all settings; whether domestic, industrial, educational or social. An epidemic as virulent and far reaching as this one has been has created the requirement for a new way of making sure every surface is deep cleaned and any trace of the virus eliminated.

Fogging machines are often used in pest control but virus elimination is one of the areas in which fogging machines excel. Is it time you considered investing in one?


How Does a Fogging Machine Work?

The versatility of a fogger means that it can be carried easily by one person to reach into every nook and cranny of the area to be cleaned. The machine works by using valve-regulated pressure to expel a fine targeted mist of anti-bacterial and disinfecting chemicals to areas as diverse as hard surfaces or porous textiles, and into the air ensuring a thorough treatment to control disease and odour at the same time. Some fogging machines can spray up to 12 metres in distance.

Fogging machines are proving their worth as effective and efficient sanitisers when used with an antiviral disinfectant, a specialist chemical which is capable of quickly killing a wide range of pathogenic viruses, and this makes them particularly suitable for clinical environments.


Where Can I Use a Fogging Machine?

Because they are effective on a wide variety of hard and soft surfaces the sanitising capabilities of a fogger are especially good in hospitals, GP surgeries and clinics and veterinary clinics. In kitchen and catering premises all hard surfaces like food preparation areas, fridges, freezers, walls, cupboards, trolleys and pvc curtains can quickly be made safe for human contact. Even soft surfaces such as curtains and cushions can be given the once over by a fogger although you should be careful to check that any delicate fabric will not be damaged by the chemicals.

Fogging machines are effective in other areas of the food industry that you may not have thought of such as within the dairy, pig and poultry industries. Milking parlours, sow and weaner sheds and poultry hatcheries can be speedily sanitised to avoid any kind of pollution which would be costly to the agricultural industry in terms of time and money.

Any workplace where there is regular and persistent use of computer equipment, desks and even rest rooms can all benefit from this form of sanitisation as can greenhouses in garden centres or other humid areas. Fogging machines can efficiently sanitise indoors and outdoors, making them a versatile and highly effective choice for those businesses aiming to keep the virus, and other germs of course, away from their premises.

Whether you’re a cleaning company looking to offer a new service to your clients, or a business aiming to lower the risk of staff, customers and visitors contracting anything from your premises, a fogging machine may be just what you need to help make your business COVID secure.

Disinfectant Fogging Machine

Fogging disinfection and sanitisation is a proven method to help eradicate infectious diseases; it is a fast, safe and thorough process for use inside or outside any building. When using the correct chemical product, it will kill 99.9% of all bacteria. It is recommended to use Viro Kill, an amphoteric terminal disinfectant to kill 99.9% of all bacteria.


What is Fogging?

  • Fogging or electrostatic cleaning is a process where Viro-Kill, a disinfectant and biocide, is dispersed into the air.
  • Viro-Kill, is a bactericidal killer, Approved to BS EN1276.
  • Using APT Fogging Machines or an electrostatic fogger produces micro-droplets of disinfectant and biocides that float in the air for around 10 minutes after application. Dispersing these micro-droplets into the air means the solution can reach areas that could not otherwise be reached by conventional cleaning methods.
  • Studies show when you use a fogger machine for fumigation, it significantly reduces the number of viable infectious pathogens by treating the surfaces and the air.


Under typical conditions, fogging is carried out for a minimum of 15–30min to enable the fog to disperse and the chemical action to occur. After fogging, an additional period of 45–60min is required to allow the droplets to settle out of the air and onto the surfaces. Electrostatic charging of chemical fogs during aerosolisation can improve the application as the droplets will be attracted to surfaces that are electrically charged.


Why is using a Fogging Machine the Best Solution to Kill Bacteria?

  • Fogging significantly reduces the number of viable infectious pathogens and harmful airborne bacteria
  • Most of our fogger machines have a range of over 13 meters with an adjustable flow to inject the perfect number of droplets for each room or space.
  • The range allows the biocidal bactericide to reach areas that cannot be contacted by conventional cleaning.
  • It is a quick, clean process and does not require the removal of any items.
  • Fogging is food safe and can be used in the food processing industry


What is the best product to use through a Commercial Fogging machine?

Viro Kill kills 99.9% of all bacteria.

Viro Kill is scientifically designed with a broad spectrum of activity and Approved to BS EN1276. The fast kill rate disinfection contains a specialised primary biocide that works quickly against enveloped viruses, HBV/HIV, Hepatitis B, Herpes simplex, Rota Virus, Bovine, Corona Virus/SARS-CoV and H1N1 Avian influenza. Viro-Kill is a food safe, high concentrate, low odour formula. It is safe to use in kitchens, food processing and manufacturing.

The Difference Between Wet, Dry & Electrostatic fogger application methods

When dry, wet or electrostatic fog produced by Foggers, the main difference is the droplet size.

APT Range of Cold or ULV foggers can disperse dry and wet fog. Their nozzles allow you to regulate both the spray volume and droplet size within a range of 5 to 50 microns.

Wet Foggers

Most Cold or ULV foggers can disperse dry and wet fog. Their nozzles allow you to regulate both the spray volume and droplet size within a range of 5 to 50 microns.  As long as you keep the droplets small, you’ll get a dry fog (to which the previously mentioned factors will apply).

APT fogger machines on normal setting deliver around a 20 to 30 microns droplet size

If you adjust the machine to produce a fog with droplets that are 20 microns or large, you’ll have a wet fog. These larger droplets are better for applications such as disinfection, mould control, or targeting specific areas with an insecticide. These larger droplets mean that the fog will wet specific surfaces and coat them thoroughly with the chosen solution.

APT fogging machines are always in stock and are delivered directly throughout the UK

Our Commercial Fogging Machines are for sale directly in the UK. Ideal for fogging and disinfecting all areas of a building to reduce risk of coronavirus.

Visit our Fogging Machines page at b> where you will also see a video of a Fogger in action.

Dry Foggers

Dry Fog usually has droplets that are 10 to 15 microns in diameter. This is because the droplets are so small that they create a seemingly dry fog.

On the other hand, a fog that has droplets that are 20 to 30 microns in diameter is considered wet fog. This fog appears to be wetter and more like a mist than a fog. All fogs whose droplets are above 30 microns are usually mist’s or sprays, not fogs.

So, based on this explanation, wet and dry Foggers differ based on the fog they emit.

Most thermal Foggers are dry foggers because their mist usually consists of droplets of around 10 microns in diameter. These foggers are perfect when you need to distribute the fog over quite a large area. This is because the smaller particles will be able to diffuse widely and travel quite far thanks to air currents and wind.

The downside to this is that the fog might not thoroughly cover the entire area you wanted to treat. This means that it might be better to fog the area at least two times for more complete coverage

Electrostatic Foggers

Electrostatic spray surface cleaning is the process of spraying electrostatically charged mist onto surfaces or objects. The spray uses a specialised solution that is combined with air and atomized by an electrode inside the sprayer.

The Electrostatic systems although highly priced work by charging liquids (i.e., cleaners, sanitisers, and disinfectants) as they pass through a sprayer nozzle. This generates charged droplets that repel one another and actively seek out environmental surfaces, Electrostatic spray uses a specialized solution that is combined with air and atomized by an electrode inside the sprayer... Because the particles in the spray are positively charged, they cling to and coat any surface they are aimed at which they stick to and even wrap around to coat all sides.


No matter which kind of foggers you use – dry, wet, cold, or thermal or electrostatic – you should experiment to see which droplet size best suits your application and the product suitability on the surface to avoid damage  This can also differ based on

• weather conditions (very windy places vs. places where the wind is a rarity),

• the treatment indoors or outdoors area (subject to health and safety whilst using electrical equipment)

• the liquid used (water-based solutions).

APT Super concentrate Virokill Anti Viral Sanitiser, disinfectant gives you almost 50 times more product for your money than other ready to use fogging solutions are safe on most surfaces

Our Viro Kill is conforms to BS EN1276, BS EN14476 & BS EN13697.

When you take into consideration all these factors and merge them with the knowledge of dry and wet fogs and the different types of foggers, you should find it quite easy to make the right decision as to what type of fogger is best for you.

It will largely depend on what type of disinfectant you are planning on using. The disinfectant solution should have information on which kind of fogger it should be used with. But in general, you can use both thermal and ULV foggers for disinfecting purposes.
