How long does a filter cartridge for a mask last?

This is a question we are frequently asked by users and one we can never answer immediately. The lifespan of a filter cartridge for gases, vapors, and fine dust is determined by various factors, which can differ greatly depending on the situation. Our respiratory protection specialists provide an answer based on an extensive Swedish scientific study.

Mechanical Filter Material Is Significantly Less Sensitive to Factors Than Electrostatic

For fine dust filters, the type of filter material used determines the lifespan. Is it mechanical or electrostatic? Their properties are completely different. Mechanical filter material is significantly less sensitive to factors such as humidity, ambient temperature, and age. For both types, besides efficiency, you need to consider the fine dust concentration. The airflow rate through the mask’s filter material also has a major impact on filter efficiency, especially for electrostatic filters. An electrostatic filter becomes less efficient as it becomes saturated with fine dust, whereas a mechanical filter actually becomes more efficient as it saturates.
