Counterfog®: definitive disinfection system

Innovative unique technology

Counterfog® is an innovative unique technique using microphysical dynamics to generate a huge  amount of submicron drops of water capable of hitting harmful air-borne particles, enveloping them, and precipitating them onto the ground. There they can be isolated and collected with procedures appropriate to their toxicity. It is a universal tool to decontaminate air and surfaces.  

Trustworthy: EU guarantee

Counterfog® disinfection system technology was created under contract number 312804 of the 7th Research & Development Program of the EU Commission (FP7). It was created and tested by a team of scientists from 10 European research institutions and universities including, among others, Universidad de Alcalá (Spain), Strathclyde University (UK), the Czech Academy of Sciences, the Bulgarian Academy of Sciences, and CIEMAT (Spain).

Fast & highly effective

It achieves really fast & massive decontamination. For instance, 99.99% effectiveness was demonstrated against Bacillae aerosols in just 1 minute of Counterfog® application. Log7-8 decontamination levels can be reached on large scale within a few minutes. This technology has demonstrated its effectiveness against chemical, biological, radiological, and nuclear toxic agents.

Both from air and surfaces

The unique dynamics generated by Counterfog® nozzles draws and aggregates particulate matter and aerosols, preventing resuspension and cleaning the air. The thin film of liquid applied on surfaces ensures decontamination with a minimal impact.

Size does matter

Counterfog® launches a dynamic fog cone made up of millions of submicron droplets (the size of viruses, bacteria, spores…). These extremely small droplets, when projected into the air, trap airborne matter (dust, aerosols, etc.). Other technologies are not effective because they use much larger droplets, which is why they only manage to displace the air in which these particles float and cannot trap them.

Versatile and easy to use

Counterfog® can be applied on a large scale to protect urban zones, sensitive and critical infrastructures. Unlike other disinfection technologies, it  does not damage electronic equipment or goods in any industry or trade, since it only uses liquid in minimal quantities. It takes only a few minutes to disinfect large areas and can be applied by untrained personnel.

Counterfog® applications

Counterfog® Products

Counterfog® Large Scale

Decontamination of toxic clouds in urban or industry areas as well as in sensitive and critical infrastructures is possible with Counterfog® Large Scale solutions.  Smoke, dust, aerosols (including microrganisms), vapours or gases can be collapsed preventing its spreading.

Counterfog disinfection barriers

Counterfog® Barriers

Nozzles barriers can be installed indoors or outdoors to remove dust or smoke or to disinfect biological aerosols from the air.  When working with potable water, they prevent volatile bioagents to be drawn in or resuspended by people.

Counterfog®’s ‘all-rounder’  are provided with the most advanced aerosol removal technology.  Manageable, comfortable, easy to use, portable & fast. Available in two powers: 1200 W and 1500 W for domestic and small retail and for heavy duty professional use.
