What is a Medical Fogger Machine?
A fogger machine is a device that converts liquid disinfectant solution into fine mist or fog. This fog spreads into the air and disinfects:
- Airborne microorganisms
- Surfaces
- Corners of rooms where normal cleaning is difficult
In simple words, a fogger machine ensures complete sterilization and infection control in hospitals and pharmaceutical industries.

What is Fogging in Hospitals & Pharmaceuticals?
- Fogging in hospitals means spraying disinfectant mist inside operation theatres, ICUs, wards, and labs to kill bacteria, fungi, and viruses.
- Fogging in pharmaceuticals ensures that medicine production areas remain 100% sterile and contamination-free.
Fogging is an important step in infection prevention and quality control.
What is a Fogger Kit Used For?
A fogger kit includes the machine, nozzles, disinfectant solution container, and power supply.
It is used for:
- Disinfection of Operation Theatres (OTs)
- Fumigation of Pharma cleanrooms
- Mosquito and pest control
- Air purification in hospitals
Types of Fogger Machines
There are different types of foggers available depending on their working principle and usage.
| Type of Fogger Machine | Description | Common Uses |
|---|---|---|
| ULV Fogger (Ultra-Low Volume) | Produces very fine mist particles | Hospitals, pharma industries |
| Thermal Fogger | Uses heat to produce fog | Mosquito and pest control |
| Cold Fogger | Works at normal temperature | Operation theatres, ICUs |
| Water Fogger Machine | Uses water-based disinfectants | General hospital disinfection |
| Portable Fogger | Small, handheld model | Clinics, labs, home use |
Procedure: How to Do Fogging in Operation Theatre (OT)?
Performing fogging in OT requires proper steps:
- Preparation
- Close all doors, windows, and AC vents.
- Switch off lights and cover medical equipment.
- Machine Setup
- Fill the fogger tank with recommended disinfectant solution (like formaldehyde or hydrogen peroxide-based).
- Place the fogger in the center of OT.
- Fogging Process
- Switch on the fogger.
- The machine will release fine disinfectant mist.
- Let the fog spread evenly in the entire room.
- Waiting Time
- Keep OT closed for 30–60 minutes.
- Allow disinfectant to settle.
- Ventilation
- Open doors and windows for ventilation.
- Wipe surfaces before next use.
Regular OT fogging is mandatory to maintain sterile environment and patient safety.
Where Fogger Machines Are Used?
Medical fogger machines are commonly used for:
- Hospitals – OTs, ICUs, wards
- Pharmaceutical Industries – Cleanrooms, labs
- Research Labs – Microbiology, pathology
- Ambulances – For disinfection after patient transfer
- Mosquito & Pest Control – To prevent malaria, dengue, etc.
- Homes & Offices – Air purification and sanitization
Fumigation Machine Solutions
The fogger works with different disinfectant solutions like:
- Formaldehyde – Strong sterilizing agent
- Hydrogen Peroxide (H₂O₂) – Safer alternative for hospitals
- Alcohol-based disinfectants
- Essential oil or herbal solutions (for mosquito fogging)
The choice of solution depends on purpose (hospital OT vs mosquito control).
Fogger Machine for Hospitals & Operation Theatres
In hospitals, foggers are essential for:
- Preventing surgical infections
- Maintaining sterile environment in OT
- Reducing cross-contamination in ICUs
- Emergency fumigation in outbreak situations
Fogger Machine for Pharmaceuticals
In the pharmaceutical industry, fogging ensures drug manufacturing areas remain contamination-free. It helps in:
- Sterile packaging
- Microbial load reduction
- Quality compliance with WHO & GMP guidelines
Fogging Machine for Mosquito Control
Apart from hospitals, foggers are used by municipal authorities for mosquito control.
- Thermal foggers are best for outdoor areas.
- They use insecticide solutions to kill mosquitoes carrying malaria and dengue viruses.
Water Fogger Machine
A water fogger machine is commonly used for:
- Spraying water-based disinfectants
- Humidification in greenhouses
- General disinfection of large halls, offices, and hospitals
