If you have a bathroom vent or a laundry room vent in your apartment, use the hose from the unit and attach/seal to the vent (because it goes outside). You most likely won’t need to turn on the vent fan as the air is being pushed out by the unit already. If you only do this during the summer months, and the bathroom vent fan is all you have then invest in some air freshener and flush faster. If you have a laundry room vent that pulls air to the outside, then use that.
