  • Product Overview

    Stop the uncomfortable and damaging effects of low indoor humidity with the Skuttle Model 86-UD Flow-Through Under-Duct Humidifier! This drum-style whole house humidifier works with your furnace to provide comfortable humidity to all the rooms of your home simultaneously. This humidifier is an excellent alternative to using a series of hard-to-maintain portable humidifiers throughout your home. With easy and quick installation and low maintenance, the Skuttle 86-UD is your one-stop solution for eliminating dry wintertime air.

    How It Works

    The Skuttle Model 86-UD Under-Duct Humidifier installs as part of your forced air heating system to distribute warm humidified air throughout your entire home. It is designed to mimic nature's process of warm air evaporation with the help of unique rotating evaporator pad or drum. As your furnace heats your home, the drum evaporator rotates continuously, wicking up moisture into the warm air stream. Warm and fresh humidified air is then propelled throughout all the rooms of your home through your air ducts. The Skuttle 86-UD Drum Humidifier is controlled by an external humidistat that makes set it and forget it operation a reality. All you have to do is set your desired humidity level. When your home's relative humidity falls below your selected humidity, the humidistat activates the humidifier, no intervention needed.

    Coverage Area

    The Skuttle 86UD Humidifier can humidify homes up to 4,048 square feet, depending on your home's insulation level. Use the guidelines below to determine whether or not this model will work for your home.

    Maximum Home Size Tight House Average House Loose House
    Total Square Feet 4,048 sq. ft. 2,576 sq. ft. 1,848 sq. ft.
    Total Cubic Feet 32,381 cu. ft. 20,606 cu. ft. 14,783 cu. ft.
    • Tight House - Tight houses have insulated walls and ceilings, vapor barriers, weather stripping on doors and windows, snug doors, snug windows, and a fireplace damper. One-half air change per hour. 
    • Average House - Average houses have insulated walls and ceilings, vapor barriers, loose doors, loose windows, and a fireplace damper. One air change per hour.
    • Loose House - Loose houses have no insulation, storm doors, storm windows, weather stripping, or vapor barriers. Two air changes per hour.

    Additional Benefits and Features

    • Output Per Day - The Skuttle 86-UD Whole House Humidifier disperses 17 gallons of comfortable moisture per day at a 120-degree F plenum temperature.
    • More Humidity - This humidifier's under duct flow-through drum design allows air to pass directly through your ductwork instead of a 6 inch bypass tube. This provides you with more humidity over whole house bypass humidifiers.
    • Mounts on Horizontal Ducts - This model is mountable on horizontal ducts as small as 12 inches wide and 8 inches high.
    • Low Energy - Electrical consumption is about the same as a 25-watt light bulb.
    • Low-Hassle Mounting Frames - The included mounting frames are easily removed when it's time for maintenance and cleaning.
    • Rust-Proof Cabinet - The humidifier features a sturdy thermoplastic cabinet that resists rust, corrosion, and warping.
    • No Impurities - As water is evaporated, common impurities, bacteria, and other pollutants are left behind, creating clean humidity.


    Use the Skuttle 86-UD Flow-Through Under-Duct Humidifier to fight dry wintry air and its uncomfortable effects throughout your home.

    What Customers Love

    • More Efficient - Drum humidifiers are generally more efficient in water usage than flow-through humidifiers. That means all water supplied to the humidifier is released into the air.
    • Lowers Heating Costs Too - Keeping your home's humidity at an optimal level can actually lower your winter heating costs, since you feel warmer in a humidified environment.

    Things To Consider

    • Consider Your Home's Size and Insulation Level - The coverage area of this humidifier depends on your home's insulation level. Use the Coverage Area guidelines above to accurately estimate how well this humidifier will treat your home. 
    • Professional Installation - Skuttle recommends that its furnace humidifiers be installed by a professional HVAC technician.
