In general, there are no guidelines as to where the air purifier should be positioned. In order to offer high air quality, however, it must be ensured that there is air circulation. The better the air can circulate in the room, the more efficient the air purifier is.
It can and should be ventilated normally. The air purifier removes all possible pollutants from the room air, e.g. even pollen that gets into the room does not feed fresh air.
We cannot give promises or precise information regarding government aid. This point of view depends on the respective federal state.
When cleaning, the KA-520 relies on the filter function of the H14 filter, with a degree of separation of 99.995%. Additional exposure to UV-C light would have no additional benefit.
It is not necessary to kill viruses on the filter with UV-C rays, as the viruses die after a few hours on the filter (a virus cannot survive without a host).
The use of UV-C also harbors additional sources of danger, such as radiation and ozone formation. For this reason we decided against irradiation with UV-C.

We always recommend taking all protective measures. In general, the well-known AHA + L rule applies and the air purifier cannot take over the L for ventilation. The air purifier helps to clean the room air from harmful aerosols.
No, the viruses in the filter are deactivated after a few hours and are harmless. It is recommended to wear normal protective clothing. This includes a mask and gloves, as other airborne impurities (bacteria, pollen, dust) have also accumulated in the filter.
