Counterfog® is an innovative unique technology developed in the FP7 EU Research and Development program for fast decontamination using microphysical dynamics to generate a huge  amount of submicron drops of water capable of hitting harmful air-borne particles -including ultrafine particles smaller than a micron- , enveloping them, and precipitating them onto the ground preventing breathing.  It is a universal tool to decontaminate air and surfaces.

Counterfog® disinfection and decontamination 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). Other tests have been performed by the prestigious Centre of Molecular Biology Severo Ochoa of CSIC.

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. Counterfog® is the only technology able to remove air-borne viruses and other ultrafine particles.

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.
