Filters for surgical procedures including a fluid pathway to transport fluid, such as smoke and/or gases, exhausted from a surgical site, a humidity regulating element located along the fluid pathway, and a filter element located downstream of the humidity regulating element such that the humidity regulating element and the filter element are in fluid communication with each other. The humidity regulating element is configured to remove or reduce humidity from the smoke and/or gases exhausted from the surgical site prior to the smoke and/or gases reaching the filter element. The filter element is configured to filter particulate matter from the smoke and/or gases exhausted from the surgical site.
