Electrostatics is a branch of physics that studies the phenomena and properties of stationary or slow-moving electric charges (Electrostatics, 2016). Electrostatic phenomena is easily demonstrated when lint is attracted to clothes, or when dust clings to a TV screen. These descriptions are examples of Coulomb’s law. Coulomb’s law states that opposite electrical charges attract and like charges repel. Electrostatic spraying has been used for many decades in painting and agriculture. EMist uses this same process to apply a charge to the liquid droplets as they are formed and just before the droplets leave the spray nozzle. These “super-charged” droplets then actively seek out negative or neutral surfaces. What’s more, as the droplets leave the nozzle, the charged droplets repel one another, keeping them from coming together and forming larger droplets. Interestingly, because of the electrostatic charge, droplets “wrap” around surfaces providing an even, consistent surface coverage.
Your staff will find the sprayers easy to use and to operate. They’ll also discover that it takes less time to cover more area and to do the job with better outcomes and more cost effectively.
Learning to use the EMist sprayers takes about an hour (online training resources).
Those involved in the prevention and control of preventable infections require a balanced approach to cost and quality to improve outcomes. Existing disinfection methods including wipes, spray and wipe, fogging, and UV lighting are ineffective or expensive. As environmental surface contamination and healthcare-acquired infections have become more defined, EMist sprayers present an effective, approved, and cost-effective alternative to applying disinfectants.
EMist sprayers use a very specialized and precise spray tip. The tip produces an average droplet size, or variable mean diameter, of 85 microns (range of 54 microns to as large as 120 microns). With a VMD of 85 microns there is much less “drift”, better surface coverage, improved surface dwell time, and the least possible suspension of liquids.
Based on industry definitions and droplet size measurements, the EMist sprayers deliver a consistent droplet size above 50 microns. This qualifies the system as a misting device. Due to the electrostatic charge of the droplets, as they leave the tip, the droplets are not suspended in the air.
Most surface areas are neutral (uncharged) or negative. Electrostatic application for surface disinfection is a method of applying EPA-registered disinfectants to a target surface area by utilizing the electrostatic force of attraction. Simply put, the electrostatic system places an electrical charge on the droplets and disperses them across a target surface area, providing a comprehensive, even coverage. This provides a consistent and uniform coverage in which the droplets adhere to vertical, horizontal and three-dimensional surfaces.
SARS-CoV-2 can remain on surfaces for hours and up to 9 days. Research has shown that microorganisms can survive on surfaces for days, weeks, and even months, and can be hidden from current spray and wipe methods. (Kramer, 2006) Using electrostatic technology provides effective, proven, safe and comprehensive surface coverage and eliminates cross-contamination of dangerous pathogens.
Any water-soluble chemical can be used in the EMist electrostatic sprayers. However, we prefer “safe and green” disinfectants. A perfect disinfectant would offer complete and full microbiological sterilization, without harming people/animals, would be inexpensive, and noncorrosive. Unfortunately, most disinfectants are potentially harmful and even toxic to humans/animals. One solution is Hypochlorous acid (HOCl). HOCl works very well against pathogens like Methicillin-Resistant Staphylococcus Aureus and Pseudomonas Aeroginosa. Though very powerful, HOCl is 100 percent safe for humans, chemical-free, non-toxic and all-natural. It has been used in the medical field for over a century. Before antibiotics were available, HOCl was used to irrigate and disinfect wounds in World War I. Today, it is used in everyday settings such as daycare centers, hospitals, and even produce sections in grocery stores.
Regular maintenance is required. A 60 second flush of the system with clean water is recommended after long periods of use and any time you switch chemicals/cleaners in the unit. Please follow the guidelines included in the operations manual supplied with the unit.
4000 square feet when spread properly.
The 14.4V lithium battery will last up to 20 full 8oz tanks.
No formal training is required. Training videos are available on the EMist website and specific videos for how to use the sprayers are located on the training memory stick.
First, check the troubleshooting section of the owner’s manual for common problem and recommended solutions. If you need additional assistance, please contact In Office Sterilization via e-mail firstname.lastname@example.org and a customer support person will follow up with you.
Yes, you are applying too much solution to an area. The key with electrostatic spraying is to keep moving and not overspray an area. The fine mist will encapsulate the surfaces you’re spraying. The recommended distance is 36-48” from target. Dry time should be not more than 2-3 minutes.
