A dehumidification system includes an evaporator, a condenser positioned next to the evaporator, and a drain pan including a mist eliminator. The drain pan is disposed at least partially below the evaporator and the condenser. The drain pan at least includes a basin disposed at least partially below the evaporator. The basin includes a sloped bottom, a first rib disposed on the sloped bottom, a second rib parallel to the first rib and including a central gap, a third rib positioned between the first rib and the second rib, and an angled rib attached to the second rib. The third rib is parallel to and shorter than the first rib. The third rib is configured to at least partially block the central gap of the second rib. The angled rib is inclined towards the third rib and configured to change a velocity vector of the air flowing through the drain pan. The mist eliminator is configured to remove water droplets from the air.
