LOWER AEROSOL CONCENTRATION IN CLOSED ROOMS
The CRT RoomGuard© is a mobile room filter whose filter system is highly effective in reducing particles and aerosols in closed rooms. RoomGuard© produces clean, germ and virus-reduced air in which the risk of disease transmission is reduced to a minimum.
No RoomGuard© leaves production in Germany without a 100 percent functional test. CleanroomTechnology’s entire know-how in engineering, design, construction, measurement and monitoring of cleanrooms has been incorporated into the development of the RoomGuard©.
Whether in waiting rooms, offices, schools, restaurants, meeting rooms or classrooms:
RoomGuard© reduces aerosols and viruses in closed rooms by up to 99,995% (behind the HEPA filter).

“THE CRT ROOMGUARD© CREATES A NEW LEVEL OF RELAXATION IN OFFICES AND RESTAURANTS.”
