When the surgeon takes the scalpel in the operating room, the highest hygiene standards must be ensured. This also applies to the air filtration. The same is true in isolation rooms, where patients could transmit infectious diseases via the air (airborne spreading). Again, filters must work reliably at all times to prevent microbiological contamination.

Viledon filter systems for hospitals

In essence, filter requirements for hospital applications can be summarized in three key points:

  • Protection of patients, visitors and staff from airborne contaminants
  • Protection against microorganisms in buildings
  • Reliable filtration of non-pathogenic particles, as these can serve as a vehicle for bacteria

To achieve the required indoor air quality, we combine air filters of different classes and designs into multi-stage systems. Generally, a 2-stage filtration system serves to remove coarse to fine particles. In operating theaters or isolation rooms, end-stage filters are used to remove even finer particles from the air.

These sensitive areas are subject to particularly strict requirements. To ensure the highest quality of clean air, the air is guided by low-turbulence displacement flow. In adjacent areas, the number of hourly air-change cycles is determined by the size of the room as well as by the equipment it contains and the numbers of people using the area. The supply of a sector with filtered air must be designed to ensure an effective flow while minimizing the risk of creating higher pressure than in adjacent areas, under all operational conditions.

How efficient is your filtration system?

Find the optimal filter solution for your plant with e.FFECT based on ISO 16890

Standardized systems for supply air filtration are frequently inefficient and do not make full use of their potential for optimization. The more specifically filter systems are customized to the respective ambient conditions and plant requirements, the greater performance and reliability they achieve.

Our experts work with you to develop the best filter solution for your plant on the basis of the testing standard ISO 16890. In the filter evaluation, typical urban and rural particle size distributions are considered based on the particulate matter fractions PM1, PM2,5 and PM10, and filter arrestance efficiencies are determined accordingly.

With e.FFECT, the electronic Freudenberg Filter Efficiency Calculation Tool, calculating the optimal filter solution is extremely simple. The local ambient conditions and specific process requirements enter directly into the calculation. Multi-stage filter systems can then be objectively compared. This simplifies the selection of the best filter concept for your needs.

Hygiene standards for maximum protection

Requirements for hospitals

Where the highest standards of air purity are required – for example in operating rooms in hospitals – airborne particles and germs must be reduced to an absolute minimum in order to protect the patients, visitors and hospital staff.

Test methods for EPA, HEPA and ULPA filters

EN 1822 and ISO 29463

In Europe, EPA, HEPA und ULPA filters are subject to classification according to EN 1822 for filtration efficiency and zero leakage. HEPA and ULPA filters are also subject to individual tests. The international standard ISO 29463 is based on European standard EN 1822 and will probably replace this standard in the future. Both standards are based on the latest particle counting methods.
Viledon air filters satisfy the requirements

VDI 6022

VDI Guidelines 6022 “hygiene requirements for ventilation and air-conditioning systems and units” defines clear specifications for the use in sensitive application areas, such as clean rooms. Viledon pocket and HEPA filters satisfy all VDI 6022 criteria without restrictions.
