Cold plasma is an ionized gas consisting of various ions. Some of these have a disinfecting effect. They have been shown to dry out the cell walls of native bacteria and enveloped viruses (such as SARS-CoV-2). Only ambient air and electricity are needed to generate cold plasma. The cold plasma is generated in our devices using a special and patented cold plasma source.

The microbiological efficacy tests and field trials show that cold plasma eliminates native bacteria, enveloped viruses (e.g. influenza, SARS-CoV-2, monkeypox) and fungi. The germ load is reduced to such an extent that the remaining germs no longer pose a danger. Cold plasma also has the significant effect of reducing unpleasant odors, plant pollen and animal epithelia.

The effectiveness of the products has been confirmed by German accredited laboratories. Furthermore, tests regarding electromagnetic compatibility (EMC) as well as electrical safety were performed by German accredited laboratories. Detailed test reports and certificates are available for this.

Yes, there are worldwide patents.

Yes, the tests were carried out by a German accredited laboratory.

No. German accredited laboratories have tested and confirmed that the devices are demonstrably harmless to health.


PLASMO®HAND is supplied fully equipped (incl. air filter, reusable water bottle with 500 ml operating water, valve closure and power supply). All that is needed is a power outlet and a suitable place. In addition, we offer a rolling base or wall mount for an additional charge.

First, the air filter must be inserted on the underside of the unit. Then the valve cap is screwed onto the bottle instead of the normal cap. The bottle can then be placed vertically in the device with the blue valve cap facing down. Before the device is started, the cover cap must be placed on the device. The device can be switched on using the on/off button. The device is now ready for use. The disinfection process starts automatically as soon as the user puts his hands into the device. Detailed assembly instructions can be found on our YouTube channel.

PLASMO®HAND is available in the Basic Edition with white-blue housing and bilingual instructions in German/English. Alternatively, for a more exclusive ambience, there is the Black & Gold Edition with a matt black and gold enclosure.

When the device is switched on, the device buzzes briefly and the on/off button lights up orange. As soon as this lights up green, the device is in standby mode and only starts the disinfection process when activated by the built-in sensors in the two openings. If the hands or any objects (e.g., mobile phone) are held in at least one of the two openings, the process starts automatically. A fine mist appears.

PLASMO®HAND only requires ambient air, electricity and operating water. The power consumption in standby is approx. 2.3 W. In operation, this is a maximum of 43 W. With a usage time of 8 s, this corresponds to approx. 0.09 Wh per application. More than 2,000 applications can already be realized with 500 ml of operating water.

The orange LED flashes when water needs to be refilled.

Basically, the use of our operating water prevents calcification of the device. In addition, this is stabilized and thus storable.

PLASMO®HAND basically works for approx. 5 years. In order to extend the service life of the device, we recommend changing the filter on the bottom of the device every six months. The filters are available from WK-MedTec.

The water should be discharged from the unit via the water outlet beforehand (see operating instructions).

In this case, please contact us or the authorized service partner (see operating instructions), we will immediately take care of a proper repair or a replacement device.

The examinations are based on certain medical standards (EN 60601-1:2006 +A1:2013 and EN60601-1-2:2015). Furthermore, the EU directives 2014/35/EU (about electromagnetic compatibility) and 2014/30/EU (about electrical equipment for use within certain voltage limits) are met.

The unique blend of cold plasma with nebulized water increases effectiveness on hands and other objects. Even on wet hands after hand washing, the disinfection performance is guaranteed. The fine mist reaches every little spot and even gets under jewelry and fingernails. Objects such as mobile phones, keys and jewelry are not damaged. In addition, the automatic and easy handling ensures higher process reliability. Our patented technology eliminates pathogens and does not affect the skin’s own flora. The hands remain soft and healthy. Did you know that plasma technology is also used to heal wounds? This means that it is also beneficial for damaged and injured skin. Alcohol-based agents cause an unpleasant burning sensation, long-term destruction of the important skin flora and thus dry, cracked and irritated skin. The durability and easy maintenance of PLASMO®HAND further saves money in the long run.

PLASMO®HAND was developed before the outbreak of the global Corona pandemic and was therefore designed from the outset to rethink hand hygiene and make it more sustainable. We generally recommend placing PLASMO®HAND wherever strangers gather, for example in entrance, passage and waiting areas. In addition, our recommendation is aimed at the food sector, care facilities, doctors and physiotherapists. Other possible uses include hotels, restaurants, event venues, cultural institutions, massage and beauty salons, educational institutions, airports, retail, offices and more. The number of necessary devices depends on the spatial conditions and visitor frequency. We would be happy to discuss this with you individually.

PLASMO®AIR eliminates up to 99.99% of native bacteria, enveloped viruses and fungi. In addition, PLASMOAIR reduces plant pollen, animal epithelia as well as odors in real time, whisper quiet and maintenance free.

PLASMO®AIR is shipped together with the power supply and securely packaged. Only electricity is required. The smaller version for 40 m² can be easily mounted on the wall with common tools.

PLASMO®AIR only needs to be connected to the power supply using the power supply unit. The device can be switched on and off using the touch control.

PLASMO®AIR is available in the Basic and Pro versions. Both require a standard 240 V (50/60 Hz) power supply and have touch controls. The devices differ as follows:

PLASMO®AIR (basic): 21 x 21.5 x 14 cm / 2.0 kg / 6 W / 22dB / for rooms up to 40 m²

PLASMO®AIR Pro: 27 x 21.5 x 65 cm / 5.0 kg / 10 W / 32dB / for rooms up to 90 m²

As soon as the device is on, the control panel lights up. The cold plasma itself is not felt and is distributed almost silently. If you hold your hand a few centimeters in front of the device, you can feel a minimal draft.

An oxidative process takes place during the elimination of existing viruses, bacteria and odor molecules. This produces a “clinical” odor. This odor can develop, especially in the first few hours. The smell will go away after a few days. The great advantage of PLASMO®AIR is that other unpleasant odors are greatly reduced, e.g. from cooking. Likewise, pleasant air is provided in rooms that are difficult to ventilate or in premises of old buildings.

PLASMO®AIR is completely maintenance-free. We recommend vacuuming the ventilation slots with a standard vacuum cleaner approximately every three months. PLASMO®AIR lasts approximately five years.

In this case, please contact us or our service partner (see operating instructions). We will immediately take care of a replacement device or a proper repair.

PLASMO®AIR is designed to make people feel safe again in enclosed spaces – even without a mask. We want to make indoor air hygiene more sustainable. We generally recommend placing PLASMO®AIR wherever many people, especially strangers, come together, e.g. in offices, waiting areas, hotels, restaurants, event locations, cultural facilities, massage and beauty salons, educational institutions, retail stores, and many more. At the same time, PLASMO®AIR is particularly well suited for public restrooms and restaurant kitchens, especially due to its odor elimination properties. Private customers can also make their own homes a little bit safer. The number of devices required depends on the spatial conditions. We would be happy to discuss this with you individually.

PLASMO®AIR continuously disinfects indoor air and surfaces in real time. No waste products are generated. PLASMO®AIR is completely maintenance-free. They are also mobile and lightweight. The barely noticeable hum does not affect learning, working or sleeping.
