Electrostatic Sprayer vs Fogger

What is an Electrostatic Sprayer

Electrostatic sprayers are devices used to apply sanitizers and disinfectants onto surfaces. These devices utilize electricity-based technology to generate charged droplets that actively seek out environmental surfaces to stick to and wrap around. This results in a uniform coating of sanitizer or disinfectant on surfaces, even in hard-to-reach areas where manual cleaning is not effective.

Electrostatic sprayers distribute liquids as a fine mist, avoiding pooling and using less product, making them cost-effective and efficient. They are particularly useful for areas with intricate spaces, bulky furniture, or heavy objects that are difficult to lift or reach underneath.

How Does Electrostatic Spraying Work

Electrostatic spraying is a technique for applying a very thorough and even coating of a disinfectant or sanitizer to a variety of surfaces and objects. When a solution is sprayed through the device, an electric charge is applied to the solution, resulting in a wrapping effect being created.

This process allows the positively charged particles in the spray to evenly coat all types of surfaces, achieving complete coverage. The electrostatic spray not only disinfects the surface it is pointed at but also wraps around objects, ensuring a more thorough and effective application of the disinfectant on all surfaces and objects.

Advantages And Disadvantages of Electrostatic Sprayers

Electrostatic sprayers offer several advantages and disadvantages when it comes to disinfecting surfaces.

The Advantages of Electrostatic Sprayers

Here are Some Advantages of Electrostatic sprayers.

1. No Hard-To-Reach Surfaces

Electrostatic sprayers can effectively disinfect even hard-to-reach or irregular surfaces. The electrostatic charge applied to the disinfectant solution causes it to adhere to surfaces evenly, including areas that are difficult to reach manually. This makes electrostatic sprayers ideal for spaces with intricate furniture or objects that are challenging to move or reach underneath.

2. Product Savings

Using an electrostatic sprayer allows for efficient distribution of the disinfectant solution in the form of a fine mist. This results in less product usage compared to traditional spraying methods. As a result, companies can save on both product costs and labor expenses while reducing chemical waste.

3. Brief Waiting Periods

The electrostatic sprayer delivers the disinfectant solution quickly, minimizing contact time with surfaces. This reduces the risk of the disinfectant pooling on surfaces and objects. As soon as the solution has dried, which often takes just a few minutes, occupants can safely re-enter the area without significant interruption.

The Disadvantages of Electrostatic Sprayers

Here are Some Disadvantages of Electrostatic sprayers.

1. More Room for Human Error

There is a possibility of human error when using electrostatic sprayers. Crew members may get distracted or forget which surfaces they have already treated, potentially leading to unsanitized areas or wasted time and product in re-treating spaces.

2. Potentially More Time Consuming

Operating an electrostatic sprayer requires the presence of a crew member and cannot be left to work independently. Each surface must be sprayed to ensure thorough disinfection, which can be time-consuming, especially in large rooms. Refilling handheld sprayers with limited capacity may also contribute to time delays.

3. Not All Surface Types Are Suitable

While most surfaces possess a negative charge that is receptive to the positively charged disinfectant solution from electrostatic sprayers, some surfaces may not have a negative charge or may be made of insulating materials. In these cases, the expected results from electrostatic spraying may not be achieved.

When to Use Electrostatic Spraying

Electrostatic spraying is specifically designed for high-touch disinfection and sanitization situations. It is ideal for use on touchpoint surfaces, such as door handles, light switches, and countertops, where there is a higher risk of contamination.

Electrostatic spraying provides a thorough and even layer of disinfectant, thanks to the electrical charge applied to the droplets. This method not only saves time by quickly covering large areas but also reduces the amount of disinfectant solution required compared to traditional trigger spray application.

Its enclosed system ensures better containment and prevents overspray, which is especially important in indoor environments.

What is a Fogger

A fogger is a device that generates fog, which is a mist-like substance that doesn’t wet or soak surfaces like traditional sprays would. The fog produced by foggers is similar to natural outdoor fog and is much airier, causing only a slight increase in humidity.

Foggers are commonly used to eliminate airborne pathogens and disinfect moisture-sensitive items such as electronics. They come in various sizes and configurations, including compact, handheld, and wall-mounted options.

When paired with high-quality disinfectants, foggers provide complete disinfection of spaces, making them an effective tool for combating germs and pests. Opting for environmentally friendly and all-natural disinfectants is recommended to ensure the safety of people, pets, and plants.

Advantages And Disadvantages of Foggers

Foggers have gained popularity during the COVID-19 pandemic as effective tools for disinfection. However, like any other technology, they come with their own set of pros and cons.

The Advantages of Foggers

Here are Some Advantages of Foggers.

1. Air Disinfection

Foggers excel in eliminating airborne pathogens, ensuring comprehensive disinfection of the air, surfaces, and objects in a room. This top-to-bottom cleaning approach is especially crucial in healthcare settings where complete disinfection is critical.

2. Variety of Options

There are different types of foggers available to suit varying needs. Hand-held foggers offer the best coverage, but they require substantial personal protective equipment (PPE) due to the risk of inhaling disinfectant. Single-use foggers, on the other hand, provide a practical alternative. They can be placed in a room, activated by pulling a tab, and left to do their job independently.

The Disadvantages of Foggers

Here are Some Disadvantages of Foggers.

1. Uneven Coverage

One drawback of foggers is that the disinfectant droplets may not land evenly on surfaces, potentially leading to spotty coverage. To mitigate this issue, it is recommended to close doors and windows and turn off fans to reduce air circulation, allowing the disinfectant to settle more evenly.

2. Longer Wait Times

Depending on the type of fogger used, the disinfection process may take anywhere from one to four hours. This extended wait time is necessary to ensure the complete deposition of disinfectant and to allow for safe re-entry into the space.

When to Use Fogger

When disinfection is required in large open spaces, fogging is the best option due to its ability to quickly and effectively cover a wide area. Fogging allows the disinfectant solution to be sprayed up to 15 meters or further, reaching all the hard-to-reach areas.

This makes it especially useful in the event of a virus outbreak in a facility, as it can be implemented quickly to help stop the spread of the virus. However, it is important to note that fogging should be considered part of the cleaning process, and additional safety measures such as protective gear and downtime may be required after fogging has been completed.

Is a Fogger the Same as an Electrostatic Sprayer

No, a fogger is not the same as an electrostatic sprayer. While foggers create a dry or cold fog that kills pathogens in the air and on surfaces they contact, electrostatic sprayers use an electrode to introduce a positive electric charge to a disinfectant solution.

This charge allows the solution to attach to surfaces and objects, ensuring complete coverage. Both foggers and electrostatic sprayers are effective tools for disinfection, but the choice between the two depends on factors such as the space, traffic, furniture, and materials that need to be disinfected.

Do Fogging And Spraying Have Different Purposes

Fogging and spraying are two different methods of disinfection, each with their own distinct purposes and advantages.

Fogging is a “dry” method of disinfection that utilizes machines to create tiny particles that can float in the air. This allows for the easy and efficient disinfection of entire rooms. However, it is important not to enter the room while fogging is taking place in order to avoid inhaling the disinfectant particles.

On the other hand, spraying surfaces with an electrostatic sprayer ensures even and precise coverage of the disinfectant solution. This method is particularly effective for complex surfaces and areas that cannot be easily accessed by fogging machines. The electrostatic sprayer applies a negative charge to the disinfectant solution, causing it to adhere to surfaces more effectively.

One key difference between fogging and spraying is the size of the particles. Spraying requires very small particles to effectively cover surfaces while fogging utilizes even smaller particles that remain airborne rather than wetting surfaces.

Choosing Between Electrostatic Sprayers and Foggers

Choosing between electrostatic sprayers and foggers depends on the specific needs of the space being cleaned. In rooms with minimal furniture, both options can deliver similar disinfection results. However, when dealing with rooms that have numerous objects or complex shapes, electrostatic sprayers are better suited as they provide precise and uniform coverage.

On the other hand, if disinfection is not frequently requested or if there are concerns about the safety of cleaning crews, a single-use fogger may be a more practical choice. It is important to carefully consider the needs of clients and the abilities of the cleaning crews before investing in new equipment.

Factors to Consider Before Choosing Electrostatic Spraying or Fogging

Before deciding whether to use electrostatic spraying or fogging for disinfection, there are several important factors to consider. Each method has its own advantages and considerations that may impact the effectiveness and safety of the disinfection process.

1. Wet vs. Dry Disinfection

Electrostatic spraying involves the application of a disinfectant solution in a wet form. This method requires careful consideration of any electronic equipment in the area being treated. On the other hand, fogging is a dry disinfection method that allows electronics to remain in the room during the treatment process.

2. Electrostatic Spraying

When using an electrostatic sprayer, the disinfectant droplets are given an electric charge. This charge causes the droplets to become naturally attracted to surfaces being sprayed, resulting in more uniform coverage. The droplet sizes range from approximately 50 to 100 nanometers, allowing for efficient coverage and minimal wasteful overspray.

3. Contact Time and Occupancy

One advantage of electrostatic spraying is that surfaces typically dry within 15 minutes, minimizing occupancy delays. However, it is important to ensure that the required contact time for effective disinfection is achieved. The contact time may vary depending on the disinfectant being used, and it is necessary to follow the instructions specified by the disinfectant manufacturer.

4. Disinfectant Selection

The choice of disinfectant is crucial for both electrostatic spraying and fogging. Consider factors such as the disinfectant’s efficacy against specific pathogens, its compatibility with the equipment and surfaces being treated, and adherence to any specific disinfectant concentration or label requirements.

5. Safety Considerations

Both methods require careful attention to safety protocols, including proper ventilation, personal protective equipment (PPE), and adherence to recommended guidelines. It is essential to select a disinfectant that is safe for use in the intended environment and to follow all safety instructions provided by the disinfectant manufacturer.

Why Electrostatic Spraying Is Better Than Fogging

Electrostatic spraying is a highly effective method of disinfection that offers several advantages over fogging. Here’s why electrostatic spraying is better:

1. User Control

With electrostatic spraying, the user has complete control over the process from start to finish. The user can work from different angles and ensure that all areas of a room are properly treated. In contrast, fogging relies solely on a machine to distribute the disinfectant, which may result in missed areas due to a lack of user presence.

2. Adjustable Volume

Electrostatic sprayers allow the user to adjust the volume of the disinfectant spray. This precision control helps optimize the amount of disinfectant used, reducing the cost and waste associated with excessive liquid usage in fogging.

3. Minimal Downtime

Electrostatic spraying requires less downtime compared to fogging. After a room has been electrostatically cleaned and dried, it can be re-entered immediately without removing the electrostatic spray. In contrast, fogging may require a longer waiting period before the environment can be accessed again.

4. Effective and Efficient

Electrostatic spraying ensures effective and efficient disinfection. The electrostatic charge applied to the disinfectant creates a magnetic attraction to surfaces, allowing the spray to reach hidden and shadowed areas. This comprehensive coverage significantly reduces the chances of missed spots, unlike fogging where some surfaces may not be adequately treated.
