The air disinfection unit can be placed on a table in the room or on the ceiling or a wall. The ideal installation height is approx. 1 to 2.5 meters to installation level (base edge of unit). The placement within the room is of secondary importance, but we recommend positioning the device in the middle of the room to be purified – provided that the necessary safety distance of 1 m to the Cubusan can be guaranteed.

Due to the flow and diffusion of the plasma in the air, it takes around 15 minutes for the hydroxyl radicals to be evenly distributed – provided that the Cubusan air purifier is in a room of no more than 120 m³. However, the unit should always be activated one hour before multiple people enter the room.

Yes, but for rooms with high ceilings the cubic volume of the room is decisive for calculating the required number of air purifiers – for example, for the Cubusan CP-120: Room volume/120 m³ = required number of Cubusan CP-120. For large rooms with high ceilings and ventilation systems, the situation must be evaluated on a case-by-case basis. In these cases, it is essential to contact the Area Sales Manager.

No. The emitted hydroxyl radicals have no effects on people, animals, or plants. Exposure is therefore harmless. Cold atmospheric plasma, such as that produced by the Cubusan, has also been used, for example, in medical wound treatment for several years now.

No, the Cubusan air purifier should be regarded as an addition to an existing hygiene concept. All valid national government guidelines and provisions on the topic of hygiene should naturally continue to be observed. This includes sneezing hygiene, regular hand washing, distancing, ventilation, and so on.

Yes, viruses are neutralized by hydroxyl radicals regardless of mutation.

The efficiency of up to 99.9 percent can only be achieved with a room temperature of 18-24 degrees Celsius and a relative humidity of 30-60 percent. A minimum humidity of 10 percent is required for hydroxyl radicals to be formed in sufficient numbers. A room volume of maximum 70 m³ should not be exceeded for commissioning a Cubusan CP-70. For the use of a Cubusan CP-120, the room volume should be no more than 120 m³.

With its Sterex plasma technology, the Cubusan air purifier is effective against viruses and bacteria as well as molds and pollen, making it a very useful instrument for improving quality of life, including for allergy sufferers.

No, however, after 25,000 hours of operation the unit must be inspected, as the plasma source may have become contaminated and must be professionally cleaned. With daily 24-hour continuous operation, this corresponds to a running time of just under 3 years or, when used during normal office hours, a usage of approx. 7 years.

If the device is used differently than prescribed, for example in rooms with heavy soiling, insect infestation, excessive humidity, or very high dust loads, the device must be checked continuously for plasma performance.
