FREQUENTLY ASKED QUESTION

In terms of height above the floor, where is the ideal placement for Dehne’s Cube CV1?
For optimal installation, it is recommended to position Dehne’s Cube CV1 at a height of approximately 1 to 2.5 meters from the floor. While the placement within the room is of secondary importance, we suggest placing the device in the middle for best results.

How far are hydroxyl radicals emitted in a room via the Cube CV1, and how long does it take for the protective hydroxyl radicals to be evenly distributed throughout the room?
The flow and diffusion of hydroxyl radicals can be achieved after approximately 15 minutes per Cube CV1 in a room with a maximum volume of 120 m³. However, it is recommended to activate the Cube Cv1 one hour before multiple people enter the room.

How long do the hydroxyl radicals emitted by the Cube CV1 remain active?
Hydroxyl radicals remain active for up to one hour.

How do hydroxyl radicals oxidize bacteria, fungi, and viruses?
Hydroxyl radicals oxidize the primary unsaturated fatty acids in the fats of the cell membrane of single-cell organisms, such as bacteria, fungi, and viruses. This destroys the cell membrane and denatures the virus.

Are the hydroxyl radicals emitted by the Cube CV1 dangerous to humans or other living organisms?
The cell membrane in eukaryotic cells, including plants, animals, and humans, has a different structure, meaning hydroxyl radicals have practically no negative effect on these cells, and humans are not at risk from exposure to hydroxyl radicals.

Does the Cube CV1 emit hazardous byproducts such as ozone or nitrogen oxides?
The values measured with the Cube CV1 show no change in the premises’ values during or after operation compared to measurements taken before use.

Does the Cube CV1 comply with the standard EN 14476 (Chemical disinfectants and antiseptics: Quantitative suspension test for evaluating virucidal activity in the medical area, Test method and requirements (phase 2, step 1))?
Yes, the Cube CV1 complies with standard EN 14476, whereby the basis of the effect is not a chemical process but rather an electrophysical one.

Is the Cube CV1 effective against mutations of the SARS-CoV-2 virus, which causes COVID-19?
Yes, hydroxyl radicals neutralise viruses regardless of mutation.

Why was the test bacterium Enterococcus faecium used in the expert statement?
The test bacterium Enterococcus faecium is recommended by the DGHM (German Society for Hygiene and Microbiology) and has been used for decades in disinfection analysis. It is much more resistant than a large number of known bacteria and viruses and also has a low level of human pathogenicity. Therefore, the test bacterium is regarded as representative of all enveloped viruses and bacteria in the RKI A+B* categories (Robert Koch Institute, Germany).

Why is more humid air better for the disinfection of germs by the Cube CV1?
Reactions are limited in absolutely dry air because water vapour content is necessary for the formation of hydroxyl radicals.

How does the Cube CV1 affect allergy sufferers, such as those with house dust allergies?
The Cube CV1 works not only against enveloped viruses but also against pollen and mold, making it a helpful tool for allergy sufferers to improve their quality of life.

Can the Cube CV1 eliminate unpleasant odours?
Yes, the Cube CV1 is able to eliminate unpleasant odours in a short period of time.

Can Dehne’s Cold Plasma (Cube CV1) remove volatile organic compounds (VOCs)?
Yes, the Cube CV1 is able to remove VOCs, especially formaldehyde, by neutralizing the gases.

What is the service life of the plasma tube in the Cube CV1?
The Plasma tube does not have a lifespan.

Will the performance of the plasma tube in the Cube CV1 decrease over time?
To retain performance, cleaning the Plasma Tube once every four months is advised.
