Properly designing operating rooms and intensive care units according to DIN 1946/4 and other standards is essential. Selecting the right filtration system ensures optimal indoor air quality, protecting patients, staff, and visitors.

Hospital ventilation systems are more complex and high-risk than standard air conditioning. Besides temperature and humidity control, key factors include pollutants, fresh air intake, exhaust air, airflow direction, and air pressure. The primary goal is to deliver clean, particle-free air based on Clean Room Classifications. While general areas require standard air quality, operating rooms and ICUs demand advanced filtration to maintain the highest purity levels.

Filtration Standards

Critical hospital areas follow DIN 1946/4, ISO 14644/1, and ISO 14644/3 standards. Additionally, the NAFA Guide to Air Filtration provides guidelines for selecting the right filters.

OP Room Classifications (DIN 1946/4-2008):

  • Class Ia – Very high bacteria reduction
  • Class Ib – High bacteria reduction
  • Class II – Standard air conditioning with bacterial control

Importance of Proper Filtration

Effective filter selection impacts air quality, energy efficiency, and operational costs. Factors such as filtration capacity, surface area, pre-filters, and airflow speed directly affect filter performance and longevity.
