Achim Thelen’s cleanroom know-how is the basis for the design of the RoomGuard^®. In rooms equipped with it, the air in the room can be filtered almost particle free.

Germs and viruses need particles – for example aerosols – to be transmitted through the air. If the concentration of germs and viruses falls to an absolute minimum, the risk of transmitting diseases through aerosols also falls. This can be reduced to almost zero with optimal design, set-up and positioning of the unit within the room.

The RoomGuard^® improves the quality of your stay and well-being in closed rooms. In the approaching corona autumn and winter when life, work and leisure time once again take place more indoors than outdoors, the RoomGuard can provide a relaxed atmosphere in gastronomy, hotels, healthcare institutions, waiting areas, kindergartens, schools and offices. 

Superspreading is reduced by design in the multiple-filter system. A complete functional test of each RoomGuard^® after production ensures 100% functionality. This also includes a filter integrity test of the H14 filter according to DIN 14644-3. The set-up and adaptation of the unit to local conditions is carried out by specialists.
