What is the primary focus of total retention filters?

The primary focus of total retention filters is to completely capture contaminants. These filters are designed to efficiently trap particles from the air stream, ensuring that harmful or unwanted substances do not pass through. This capability is particularly important in applications where air quality is crucial, such as in cleanrooms, hospital environments, or any area where sensitive equipment is located.

Total retention filters typically have a high dust-holding capacity, which means they can retain a significant amount of contaminants without losing their effectiveness. This design not only helps in maintaining a clean environment but also protects downstream equipment from potential damage caused by particulate matter.

In contrast, options that mention minimizing airflow, allowing some contaminants to pass, or maintaining low pressure drop do not align with the primary goal of total retention filters. While managing airflow and pressure drop can be considerations in filter design overall, the main objective of these filters is to ensure comprehensive pollutant capture.
