An isolation or quarantine room is designed to isolate patients infected with organisms that spread through tiny airborne droplets. Alternatively, these cleanrooms are used to protect particularly vulnerable patients – for example, during chemotherapy or after a bone marrow transplant – from external risks.

These isolation and quarantine areas are designed according to defined requirements. Unfortunately, such rooms are quite costly and are only used for a few days each year. The technical setup of conventional systems is based on air treatment with HEPA filtration, which means the system must remain in permanent operation – even without patients. This is not a sustainable solution, especially when considering life-cycle costs. For these reasons, hospitals often have only a few central isolation and quarantine rooms available, and patients must be transferred to these specialized units when needed.
