The filter is manufactured as a F7 filter under EN 779 - this classification is based on the average efficiency of the filter in capturing 0.4μm particles. MERV 13 is the ASHRAE approximate classification for F7 filters.

MERV 13-16 provides filtration efficiencies near HEPA while not sacrificing the airflow/process rate. This captures the vast majority of particulates and it allows a focus on VOC & gaseous contaminant removal. We will release HEPA filters soon for applications sensitive to particulates.

It is recommended to replace the MERV 13 filter every 2-3 months. The activated carbon should be replaced every 2-3 months. For higher-load applications the carbon should be replaced upon the reemergence of odors as the lifetime is highly dependent on filament/print settings.
