How do disinfectant foggers work?

All foggers work by filling the room with an answer with disinfectant properties. There are a variety of varieties of disinfectant fogger machines available on the market, which give differing kinds of fogging remedy. Choosing the proper remedy to your facility will rely upon its use, potential pathogen exposures, and the surfaces to be disinfected. The most typical therapies are:

  • Chemical fogging
  • Vaporized hydrogen peroxide
  • Ozone
  • Chlorine dioxide
  • Ionization
  1. Chemical fogging
    A chemical fogger could be a purpose-built, everlasting construction in a manufacturing facility or warehouse, or a cellular unit introduced right into a office as wanted. Chemical foggers work by meting out a high quality mist of disinfectant resolution till the environment is supersaturated. This is applicable a good coating of resolution to all surfaces within the room, in addition to disinfects the air. The size of the remedy depends upon the dimensions of the world being fogged, however sometimes takes 30-60 minutes to finish, with an extra 60 minutes or extra for the mist to dissipate and the air within the room to return to breathable ranges.
  2. Vaporized hydrogen peroxide (VHP)
    This can be a fashionable technique of disinfectant fogging utilized in medical settings and pharmaceutical environments, for cleanrooms and related. Cleansing with VHP includes the extra step of dehumidifying the room, and takes longer to finish. Normally VHP lasts 2-Four hours fogging adopted by aerating with clear air to render the room protected to be used.

As a way to deal with a office with ozone, the room should be humidified earlier than ozone era, and cleared with recent air after the remedy. This sort of fogging normally takes 30-90 minutes from begin to completion. The use of ozone as a fogging agent is mostly inadvisable in areas with corrodible metals comparable to aluminum, zinc, copper and iron. People are notably delicate to ozone, and it’s extremely reactive as soon as it has entered the respiratory tract, so additional precautions have to be taken to utterly air the room after fogging has been accomplished.
  4. Chlorine dioxide (ClO₂) remedy
    Chlorine dioxide is an efficient selection for fogging as a result of the fuel breaks down into innocent salts. Nevertheless it’s an unstable compound that needs to be generated on location, and requires strict temperature and humidity parameters that make it unsuitable for all functions. Typically, chlorine dioxide is generated utilizing sodium chlorite and chlorine fuel, so there is a component of threat concerned in dealing with the dangerous fuel throughout this course of. Chlorine dioxide fogging ought to due to this fact all the time be carried out by a educated and licensed skilled.
  5. Ionization
    This course of includes passing air over ionizing tubes to create charged ions that search out and neutralize naturally charged airborne microorganisms. Ongoing disinfection could be achieved with ionization by releasing a managed quantity of optimistic and damaging ions, and some business items produce a continuing provide of ionized radicals to consistently keep a clear atmosphere.
PROS AND CONS OF FOGGING METHODS
METHOD PROS CONS
Chemical fogging Comparatively quick technique, widest vary of options Dangerous to breathe, extra more likely to linger
Vaporized hydrogen peroxide Extremely environment friendly, focused fogging Can’t work on biofilms, requires low humidity
Ozone Straightforward to supply on web site, quick, no residue Unstable compound, can’t be saved
Chlorine dioxide No dangerous residue Requires strict humidity/temperature parameters, makes use of chlorine fuel
Ionization Lengthy-lasting outcomes, widest floor protection Much less efficient than different strategies at treating all micro organism

Usually, misting a room leads to some surfaces remaining untreated, and mist can condense and trigger runoff that’s problematic round electronics and damp-sensitive tools and surfaces. 

Disinfectant foggers vs. electrostatic sprayers

Electrostatic sprayers carry out an analogous perform to moist foggers, however they positively cost particles as they’re distributed. Most surfaces are negatively charged as a result of they’re naturally grounded, and so entice the positively charged droplets. This results in a extra thorough and even coating of disinfectant throughout all surfaces, even these which are tougher to succeed in with conventional moist spraying strategies.

What are ULV foggers (Extremely Low Quantity)?

Extremely Low Quantity (ULV) foggers are moist foggers that produce smaller particles than customary moist foggers or misters. ULV expertise mitigates some of the downsides of moist fogging, because the smaller droplets stay suspended within the air longer and obtain higher distribution all through the remedy space. 

Are disinfectant foggers protected?
