The FC-2002 is a good choice if you regularly use your M2 for engraving and cutting and want a dedicated solution for smoke and odor filtration.
If you frequently run the M2 for extended periods, cut thicker materials, or operate multiple laser machines, a higher-capacity system such as the FumeClear FC-350 or XL Series may be a better fit.
For everyday xTool M2 users, however, the FC-2002 offers a practical balance of airflow, filtration, and compact size.
