1. A surgical evacuation system, comprising:
a pump;
a motor operably coupled to said pump;
a flow path fluidically coupled to said pump, wherein said flow path comprises a first filtering path and a second filtering path;
a sensor positioned along said flow path upstream of said pump, wherein said sensor is configured to detect a parameter of a fluid moving through said flow path, and wherein the parameter comprises a liquid-to-gas ratio; and
a control circuit configured to:
direct the fluid along said first filtering path until the parameter detected by said sensor exceeds a threshold parameter; and
direct the fluid along said second filtering path when the parameter detected by said sensor exceeds the threshold parameter.
