Calculators and checklists

  • A portable dehumidifier running next to a window covered in condensation

    Dehumidifier size calculator

    Enter the area and how damp it is (or your hygrometer reading). You get the capacity range from ENERGY STAR’s sizing chart, in pints per day.

  • Water droplets condensing on a cold metal pipe

    Dew point calculator

    Enter air temperature and humidity, and optionally a wall or pipe temperature. You get the dew point and whether that surface will condense.

  • A gloved hand scrubbing a concrete wall with a sponge

    Can I clean this mold myself?

    Five yes-or-no questions based on EPA guidance. You get one of three answers: do it yourself, call a professional, or fix the moisture first.
