DOP testing and particle measurement for clean rooms and facilities with high air quality requirements

HRS Luftteknik performs DOP testing, particle measurement, and integrity testing for companies working in environments with high air quality requirements, including cleanroom facilities, e.g., in the pharmaceutical industry and pharma, food production, and hospitals. The tests document the air quality, filtration capacity, and tightness of HEPA filters so that the facility can be kept in compliance with applicable requirements and standards.

Professional tests carried out by specialists give our customers peace of mind and documentation that the installations are working as they should – while also ensuring operational reliability and economic value.

What is a DOP test (integrity test)?

A DOP test – also known as an integrity test – is used to check whether a HEPA filter is completely sealed and filters correctly. The certificate from the test documents both the filtration capacity and the overall tightness, which is crucial in clean rooms and areas with requirements for documented clean air.

HRS performs integrity testing of HEPA filters as part of its quality assurance of air handling systems. The testing is essential to ensure that the systems meet standards for clean rooms, air filtration, and operational reliability.

Particle measurement – documentation of actual air quality

A particle measurement or particle measurement test shows whether the desired air quality has been achieved in an area. In clean rooms, the measurement is used to check whether the installation meets the requirements, and in other process areas, the measurement can be used to assess the need for ventilation or filtration.
Particle counting documents the level of particles in the air and provides a clear basis for any improvements. We perform particle measurements in production environments, hospitals, laboratories, and other facilities with controlled air quality requirements.
