Frequently Asked Questions

About The E-Mist System

What is the E-Mist disinfectant application system?

The E-Mist electrostatic disinfection application system is an effective and cost effective alternative to existing facility disinfection methods. The system is patented, providing a unique positive charge to liquids.

How does E-Mist compare to other surface disinfection systems?

Those involved in the prevention and control of preventable infections require a balanced approach of cost and quality to improve outcomes. Existing healthcare disinfection methods including wipes, spray and wipe, fogging, misting, and UV lighting are ineffective or expensive. As environmental surface contamination and healthcare-acquired infections have become more defined, the E-Mist electrostatic disinfection application system presents an effective, approved, and cost effective alternative to health care facility disinfection procedures.

What is electrostatics?

Electrostatics has been around and used for decades in the automotive, agriculture, inkjet and photocopier industries. Electrostatics is easily understood: opposite charges attract and like charges repel. Two positively charged things ( + and + ) will repel each other. Two negatively charged things ( – and – ) will repel each other. Using this natural electrostatic phenomena, E-Mist developed and patented a breakthrough disinfectant application technology and system. The E-Mist Electrostatic Systems place a positive ( + ) charge on the liquid droplets as they leave the spray nozzle. The dispersed droplets spread out more evenly and seek out a negative ( – ) or neutrally charged surface (most surfaces are either negative or neutral). The end result is that the disinfectant is more targeted, provides more uniform coverage with less waste, and just like a magnet, attracted to an oppositely charged surface with remarkable force.

What is the E-Mist System droplet size?

E-Mist disinfectant application system uses 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” as compared to foggers, better surface coverage, improved surface dwell time, and the least possible suspension of liquids.

What’s the difference between an aerosol, mist, and fog?
  • Aerosol: is a colloid of fine solid particles or liquid droplets, in air or gas. Simply defined by the CDC/NIOSH as tiny particles or droplets suspended in air. (>0.5 microns)
    -The liquid or solid particles have a diameter mostly of smaller than 1 micron or so.
    -Aerosol usually refers to an aerosol spray that delivers a consumer product from a can or similar container.
  • Mist: a fine mist is formed when a finely divided liquid is suspended in the air. Examples include paint spraying, condensation of water, vapor to form a fog or rain. (10-15 microns)
  • Fog: vapor condensed to fine particles of water suspended in the lower atmosphere. (2-30 microns)
    -Fog produces an uncontrollable drift. Disinfecting using fog can be dangerous and hazardous.
Is the E-Mist System a fogger? Sprayer? Mister?

Based on industry definitions and droplet size measurements, the E-Mist system delivers 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. 

Does the E-Mist System suspend liquid droplets?

No. The E-Mist disinfectant application system uses the properties of an electrostatic charge on any water soluble chemical. Due to this charge the droplets are actively looking for a surface to attach and thus they are not suspended.

What does the CDC say about disinfectant fogging?

We’ve included the following statement from the CDC website.

CDC and HICPAC have recommendations in both 2003 Guidelines for Environmental Infection Control in Health-Care Facilities and the 2008 Guideline for Disinfection and Sterilization in Healthcare Facilities that state that the CDC does not support disinfectant fogging.

Specifically, the 2003 and 2008 Guidelines state:
– 2003: “Do not perform disinfectant fogging for routine purposes in patient-care areas. Category IB”
– 2008: “Do not perform disinfectant fogging in patient-care areas. Category II”

These recommendations refer to the spraying or fogging of chemicals (e.g., formaldehyde, phenol-based agents, or quaternary ammonium compounds) as a way to decontaminate environmental surfaces or disinfect the air in patient rooms. The recommendation against fogging was based on studies in the 1970’s that reported a lack of microbicidal efficacy (e.g., use of quaternary ammonium compounds in mist applications) but also adverse effects on healthcare workers and others in facilities where these methods were utilized. Furthermore, some of these chemicals are not EPA-registered for use in fogging-type applications.

These recommendations do not apply to newer technologies involving fogging for room decontamination (e.g., ozone mists, vaporized hydrogen peroxide) that have become available since the 2003 and 2008 recommendations were made. These newer technologies were assessed by CDC and HICPAC in the 2011 Guideline for the Prevention and Control of Norovirus Gastroenteritis Outbreaks in Healthcare Settings, which makes the recommendation: “More research is required to clarify the effectiveness and reliability of fogging, UV irradiation, and ozone mists to reduce norovirus environmental contamination. (No recommendation/unresolved issue)”

The 2003 and 2008 recommendations still apply; however, CDC does not yet make a recommendation regarding these newer technologies. This issue will be revisited as additional evidence becomes available.

Will the E-Mist System delay patient admissions or other procedures?

The E-Mist disinfectant application system is used after the patient room is effectively cleaned (see CDC Guidelines here). After the application is complete the room can be used in as little as 10 minutes. However, always refer to the chemical manufacturers product label for re-entry criteria (click here for Selected EPA-registered disinfectants).

Is the E-Mist System practical enough for continuous use throughout our facility?

Yes. The E-Mist disinfectant application system can be used in various healthcare settings including, but not limited to patient rooms, common areas, operating rooms, triage areas, patient transport vehicles, nurse’s stations, emergency rooms, hallways, therapy areas, restrooms, scrub in areas, etc.
