This is a two-part moisture control kit: the AlorAir Helios MP35 crawl space dehumidifier paired with the VentirMax 570SD ventilator fan. The dehumidifier pulls damp air down to a set humidity level, while the ventilator brings in outside air to flush stale, humid air out of the crawl space. It suits homeowners fighting musty smells, condensation and wood rot under the house. Against buying either unit alone, the combo covers both drying and air exchange, which is the usual fix for a sealed or poorly vented crawl space.
