What Reddit Says

"i would only use a cover so it covers the top grill. that will prevent debris from falling into the cabinet. leave the rest open to the elements."

"When the unit runs the whole mesh balloons out. Even though its mesh, if it causes enough resistance to balloon out like that, then it's causing a restriction of airflow."

"I would estimate it would impact efficiency by 5-10 percent"
