If an air exchange basement ventilation system is not an option for you, a simple fan and dehumidifier combination can meet your basement ventilation system. A fan can expel moist air of house if ventilated properly. A portable fan box can be placed in a bulkhead or door to outside, but note that doors should be open to moist air can escape. A dehumidifier is perhaps a more effective method. This device absorbs moisture in air and trapped in a tank inside its shell.
