Our SaniDry™ dehumidifier & air systems

Even a basement with an effective waterproofing system can still develop moisture and mold problems and may feel damp. Concrete walls and floors continually absorb moisture from the soil and release it into the air in your basement, and store bought dehumidifiers simply aren't strong enough to solve the problem.

The latest generation of SaniDry™ dehumidifiers is more powerful and energy efficient than ever! Each one includes a comprehensive, written warranty upon installation. Each SaniDry™ installs with a powerful blowing motor that circulates dry air throughout the space, aggressively drying out your basement or crawl space. Collected water can be drained into a sump pump pit, a section of your perimeter drain, or away via a condensate pump. Our installers can provide you with either of these two award-winning dehumidifier systems:

  • SaniDry Sedona Dehumidifier

    SaniDry™ Sedona dehumidifier

    The SaniDry Sedona is the world's most efficient, high-performance dehumidifier and filtration system, without a bulky heat exchange core. With its small size, it takes up less space in a basement and easily fits in small crawl spaces.

    Benefits:

    • Eliminates damp, musty odors by drying and filtering air
    • Costs less to run than other dehumidifiers
    • Filters mold spores, dust mite droppings, dust and other particles
    • Set it and forget it - Sedona does the rest with automatic drainage and humidity sensing

    System features:

    • ENERGY STAR® certified
    • Removes up to 95 pints of water per day
    • Moves over 300 cubic feet of dry air per minute

  • SaniDry XP Upright Dehumidifier

    SaniDry™ XP upright dehumidifier

    System features:

    • Digital control panel
    • Ductwork compatibility for drying finished spaces
