    Crawlspaces or basements tend to have increased humidity levels. This is mainly because these spaces are either partially or completely underground. Once the moist air comes into these spaces, the moisture condenses on the walls or floor. This causes increased dampness.

    Powerful dehumidifier

    We have tried other brands. With our new unit, Model HDI90, it brought the rh down to 38, which we never could previously. Plus, it cycles on and off, runs as needed.
