Care and Maintenance of Filters in Cleanrooms and Air Handling Units

Contamination control depends on a reliable filter and ventilation system. A malfunctioning or faulty filter can introduce contaminants into a controlled environment resulting in significant risks or damages. Filters need to remove impurities from the process stream but avoid transferring impurities that could settle on a device or products surface and a well-designed system with suitably selected filters should be relatively hassle free if properly maintained.

Gas Phase Filtration

Gas phase filtration is a way of removing gaseous contaminants from the breathing air in the laboratory space. The possible first step in achieving standard compliant clean laboratory air is to remove the source of gaseous contaminants but sources are created by processes that may be key processes carried out in the laboratories or occur naturally which can only be modulated and not eliminated completely1, leading to a need to install a gas filtration system that is properly designed for the air cleaning needs of the laboratory on a case-by-case basis.
